How To Resume Download in Mozilla Firefox After Our Computer Shutted Off Suddenly

Sometime, when we were downloading something using Firefox, because of electricity and another unknown causes, our computer was suddenly shutted off and our download was also stopped. It is OK if the file size of the download is small, but how does if the file size is big (1 GB maybe) and we have done download 600 MB size ? Oh My God that must be crazy -_- And so what to do ?

Hey don't be mad, happily I've found the solution. Here are the solution :

1. Turn on your computer

2. DON'T EVER RUN FIREFOX or YOU WILL LOSE YOUR FILE

3. Go to Download folder

4. You will find two files that you are downloading

   For example : Video.mp4 and Video.mp4.part

5. Copy the file Video.mp4.part to another place whatever you like (e.g. Desktop)

6. Now, open Firefox and open Downloads dialog box.

7. Our previous unfinished download process will be resumed FROM ZERO :D

8. Pause the download.

9. Go to Download folder and now you will find only one new file Video.mp4, delete it and replace it with the the previous backed up file Video.mp4.part that we stored at Desktop. Rename it as Video.mp4

10. Go to the Firefox Download dialog, and resume the Download.

11. Now, you will see, the Download will be resumed from last Download that we have reached before our computer shutted down suddenly (hurrayy!).

That's it, hope it will be useful for you. Happy penguin forever ^_^

How To Easily Install Latest Adobe Flash Player Plugin in Ubuntu / Debian / BlankOn / Any Other Linux Distro Linux Using Offline Installer

Flashplayer works well
[click to enlarge]

Today, video tutorial or video preview is became trend, since internet access has became more cheap and more fast. The format that used is Adobe Flash Video with .flv file format. It is small and so portable to be included in our website. One successful internet website that using this technology is Youtube, a personal video broadcasting owned by today biggest internet king maker Google.

To access Flash Video, we need flashplayer plugin and if we has good internet connection, we could install it in Ubuntu very simply by Ubuntu Software Center. But, many of us have not good connection yet so installing flash plugin by this way is a trouble. Or, we need offline installer so in other times if we need to clean install our Ubuntu system, we don't have to get online again to just install a plugin.

One thing to do is very simple. Go to Adobe Flashplayer Download Page, and install flashplayer plugin package and install it manually to our Ubuntu system. At Adobe page, choose the latest flashplayer plugin, and at "select version to download" dropdown menu, choose the .tar.gz for other Linux (not APT for Ubuntu 10.04+).

Then we will get flashplayer-bla-bla.tar.gz package and the next steps to do are :

1. Extract it by right click in nautilus/file manager and Extract Here

2. We will get one file and one folder : libflashplayer.so (the main file) and usr folder (consists Adobe Flash Player Configuration. This folder is just optional).

3. Move libflashplayer.so to the directory /usr/lib/mozilla/plugins by terminal

   sudo mv libflashplayer.so /usr/lib/mozilla/plugins -v

4. Then, move the usr folder into usr directory in our Ubuntu system (this is optional, we don't have to do this if we don't need it) by terminal :

   go to usr directory we have extracted (ex : we put it in home or wherever we like to maybe /home/Downloads)

   cd usr

   then move it into /usr folder in our system

   sudo cp -rf ./* /usr -v

5. (Re)start Firefox and go to any site that using flash medias and we will get the latest flashplayer plugin work well in our Ubuntu system. Now, since Flashplayer version 11.x, will also get Adobe Flash Player Preferences to do some things about flashplayer configuration.

6. Just repeat the steps if we have to reinstall our Ubuntu System (maybe for the newer Ubuntu release).

System Specification :

Lubuntu 11.10 Oneiric Ocelot

Flashplayer 11.2.r2

Mozilla Firefox 13 (Aurora build)

Researchers discovers keylogging threats in Mozilla

Security researcher Mario Heiderich reported to the maker of Firefox last year that he had found an unusual vulnerability in the browser and two other Mozilla products that run on the Gecko engine, Thunderbird, and SeaMonkey. Based in the relatively new technology that allows for animated complex vector graphics in the browser, called SVG animation, the vulnerability allowed for a malware writer to detect key strokes even when JavaScript was disabled.

Basically, he found a way to turn innocuous Web pages into keyloggers. Mozilla patched the vulnerability in Firefox 9, Thunderbird 9, and SeaMonkey 2.6. Then, as is standard operating procedure, they announced to the public what the threat was and that it had been fixed. But the real threat may lie in what the threat wasn't: it wasn't based in JavaScript.

"The basic premise of my research currently is scriptless attacks, meaning attack vectors working in a post-XSS world," Heiderich said in an e-mail. He defined a "post-XSS" world as one where the cross-site scripting attack had been more or less minimized by technologies like sandboxed iFrames, Mozilla's e-mail client Thunderbird and Firefox's Content Security Policy, the JavaScript blocking browser add-on NoScript, and Windows 8.

"The desired goal was to do keystroke logging in the browser, doing so without necessitating JavaScript, so even if you turned off JavaScript it would work," said Jeremiah Grossman, Chief Technical Officer at computer security research firm White Hat Security. "All the browser developers are fixing cross-site scripting. What half a dozen researchers are exploring is what you can do attack-wise in a browser without JavaScript. They're discovering that there's still quite a lot you can do in the browser."

This particular SVG keylogging attack was quite nasty, said Chris Eng, vice president of research at Veracode, a computer security research firm. "The way [it] works is that [the bad guy] binds the letter "a" to an action that causes the browser to sliently issue a request for http://evil.com/?a. Pressing "b" would trigger the browser to silently issue a request for http://evil.com/?b. By "silently" I mean that there's no visual cues to the user that anything is happening--if you were monitoring the network you would see the requests. As long as the attacker controls evil.com and can access the web server logs, he can piece together what the victim is typing, one character at a time."

Eng noted that this kind of problem always erupts whenever new standards are rolled out, especially with "extremely detailed and sometimes difficult to understand" attributes. You don't have to go far to find evidence of this, either. Both Mozilla and Google offer hefty bounties for bug-hunters. Eng both cautioned against screaming that the sky was falling and said that this kind of attack was inherently more interesting to researchers.

As unlikely as Eng said it is for an average browser user to fall victim to these atypical but hard to implement attacks, Heiderich warned that it's not anomalous. "The SVG keylogger is just one example of many, and by far not the most impact ridden one," said Heiderich.

Another factor is that the major browser makers, including Google, Mozilla, Microsoft, Apple, and Opera, are all fairly responsive to fixing these threat vectors when discovered, said Grossman. But that doesn't mean that there aren't steps for the home user to take.

One way to minimize the risk from this kind of modern threat is to compartmentalize your risk, he said. "The best way [to protect yourself] is behavior, not product. Whether in Firefox, IE, or Chrome, I would use any one of the major browsers for secure browsing, such as banking or Facebook. For promiscuous browsing, such as news surfing, I use a different browser.

Eng concurred and said that there aren't many defenses against attacks that don't rely on JavaScript. "You usually have to just wait for the browser bugs to be fixed. So my options are more limited--either don't use that browser at all, use a completely separate browser for trusted sites versus untrusted ones, [or] stay off the Internet."

5 Superb Mozilla Firefox Secrets !!!

While Firefox might be your chosen browser for its speed, useful add-ons, and open-source culture, it's also packed with many useful built-in features.

I've tried to dug through Firefox's endless list of features to find you the best, little-known secrets you can start using right now.

1. Customize search with Smart Keywords
A little-known Firefox feature lets you run searches within any given Web site from the browser's address bar. For example, to search for "TouchPad" within Amazon.com, all you'd have to do is type "amazon touchpad" in the Firefox bar.

To create a smart keyword, head to a Web site and locate the search field. Then, right-click the search field and select "Add Keyword for this search...". Create the bookmark, store it in a folder, and your smart keyword is now enabled. Try it with reference sites like Wikipedia and IMDB for quick access to answers.

2. Open multiple Web sites at launch
Who says you can have only one home page? You can set Firefox to open all your favorite Web sites at launch. For example, I'd like Prohackingtricks, Facebook, and Twitter to launch every time I open my browser.

In Firefox, go to Options > General. In the home page field, enter URLs separated by pipes. For example "http://www.prohackingtricks.blogspot.com | http://www.facebook.com | http://...." and so on. Then, hit "OK" and relaunch your browser to see the magic happen.

3. Bookmark an RSS feed
If you check certain Web sites frequently, especially news sites, you can create a bookmark that automatically updates with new stories from that feed. For example, Firefox stocks your toolbar with a "Latest Headlines" bookmark, but you can create your own.

Right-click the Firefox toolbar and select "Customize...". Then, drag and drop the RSS logo to the toolbar. Now, head to the site you want to subscribe to and click the RSS button in the toolbar. Then, enter the name of the bookmark and click "Add".

4. Take your settings on the go
Instead of re-adjusting Firefox--bookmarks, passwords, etc.--every time you use a new computer, take all your accounts and settings on the go. This is done by simply installing Firefox on a portable USB drive, and inserting into any computer you use.


5. Master keyboard shortcuts and mouse gestures
Firefox has built-in shortcuts to help you browse a lot faster. For example, there are shortcuts for rotating through tabs, re-opening a closed tab, and toggling Private Browsing. View the full list here.

Firefox has mouse gestures, too. Although they're not as elegant as Mac OS X gestures, they'll become second-nature after some practice. For example, Shift + scroll down sends you back, and alt+scroll lets you scroll by line.

For advanced gestures--like reloading a page by drawing a circle with your mouse--check out the FireGestures add-on.

I am definitely sure there are still great tips you might know that I've omitted, please do share them in the comments below.

Mozilla Releases Firefox 6 for Coders

Mozilla has officially released Firefox 6, offering a new JavaScript editor and several other tools aimed at web developers.

Over the weekend, the open source outfit posted the latest stable version of Firefox to its FTP servers, but the browser wasn't formally released on the web until Tuesday.

Firefox 6 is the second incarnation of the browser released under Mozilla's new quarterly development cycle. Previously, the organization rolled out a new Firefox every eighteen months or so, but then Google upped the ante.

With the latest version, Mozilla says, it has improved the startup time of Panorma, a means of organizing your browser tabs, and it has tweaked the "Awesome Bar" – the Firefox address bar – to make it easier to identify exactly where you are on the web. But the biggest changes are for developers.

Mozilla has added a text editor called Scratchpad that lets developers enter, execute, test, and tweak JavaScript code. The idea to offer an alternative to Firefox's Web Console or the Firebug command line, which are designed around a single-line interface. "Interaction with Scratchpad is quite different. It throws away the 'one line of input gives you a line of output' interaction in favor of a text editor that knows how to run JavaScript," Mozilla says.

But if you prefer the Web Console, Mozilla has updated it as well, improving the auto-complete tool and letting you change where the console is located. In the past, the console was anchored to the top of the browser window, but you can now move it to the bottom or open it in a separate window.

The open source outfit has also added a "Window.matchMedia" API to help developers optimize their site or web app across disparate platforms, and "Prefixed WebSockets" and "server-sent event" APIs, designed to facilitate communication between Firefox and back-end web servers.

Packed with all sorts of additional security and bug fixes, Firefox is available for Windows, Mac, and Linux. You can download it here.

Mozilla also released a new version of Firefox for Android on Tuesday, adding a new welcome screen designed to provide quicker access to various tools, working to improve image rendering, and rolling in a few tools for those building mobile web apps. This includes a "single touch events" API, for detecting screen touches and gestures, and IndexedDB API, which provides local database storage for apps that need to work offline.

The new Firefox for Android is now available from Google's Android Market.

Firefox 5 Now Available for Download

Just three months after the release of Firefox 4, Mozilla has pushed out Firefox 5 for the desktop and Android devices.

That’s a big change from the two years it took to move from Firefox 3.5 to Firefox 4. Firefox 5 is part of Mozilla’s new rapid release development cycle. This cycle, which is more akin to what Google does with its Chrome browser, promises faster, more iterative updates. With any luck, Mozilla expects Firefox to hit version 7 by the end of the year.

Visually, Firefox 5 looks identical to Firefox 4. Everything we said in our Firefox 4 review applies to this release.

Rather than reinventing the wheel, Mozilla has added better support for web standards, fixed some bugs, made performance enhancements and added a few additional code touches.

The big new features, courtesy of the release notes include:

• Support for CSS animations


• Better visibility for the Do-Not-Track header preference


• Improved canvas and JavaScript support


• Better standards support for canvas, HTML5, XHR, MathML and SMIL


• Better tuned HTTP idle connection logic

In another move that mimics what Google does with Chrome, Mozilla now has more options for users who want to partake in the beta and testing process. In addition to nightly and beta channel releases, users can also opt to use the new Aurora channel, which will give users access to features before they hit beta, but with limited QA testing that you don’t get with nightly releases. This is akin to Chrome’s developer channel.

In my tests, Firefox 5 is fast — even faster than Firefox 4. I also love the more frequent update cycle, because it means that the browser will be more able to support the latest and greatest browser features.

To update to the latest Firefox, click on the “check for updates” button in the “About Firefox” menu. In the comments, let me know your thoughts of the new Firefox and its more frequent release cycle.

Firefox 5 Around the Corner: To Be Release Soon

The official release date of Firefox 5 has been set to June 21, which is three days from today. If you do not want to wait until then to play around with the latest stable release of the popular web browser, you can go ahead and download the browser for your language and operating system from the official Mozilla ftp site. As with all releases that appear there, there is a slim chance of last minute bugs that could force Mozilla to pull the release and replace it with another one. If you want to be on the safe side, or want to upgrade or install Firefox 5 in a productive environment, it is better to wait until the official release announcement.

So what’s new in Firefox 5? The release notes list the following new features and changes:

• Added support for CSS animations
• The Do-Not-Track header preference has been moved to increase discoverability
• Improved canvas, JavaScript, memory, and networking performance
• Improved standards support for HTML5, XHR, MathML, SMIL, and canvas
• Improved spell checking for some locales
• Improved desktop environment integration for Linux users
• WebGL content can no longer load cross-domain textures
• Background tabs have setTimeout and setInterval clamped to 1000ms to improve performance
• The Firefox development channel switcher introduced in previous Firefox Beta updates has been removed

Those are almost exclusively under the hood changes, some may be noticeable on day to day like the improved performance.

It should be noted that Firefox 5 introduces HTTP Transaction sorting by CWND which can improve page loading times considerably. See Firefox 5 Gets Faster Connections, Up Next: Memory Improvements for an in depths review and explanation of that feature.

The do not head tracker preference has been moved to the Privacy tab to get more exposure. Users can activate it to send a “do not track” request to each website they open in Firefox.

Interested users can access the complete list of bugs fixed in Firefox 5 here. Each entry links to Bugzilla where additional information can be found.

The latest version of Firefox 5 can be downloaded from the official Mozilla ftp server. It is likely that most Firefox release mirrors will offer the new version on their servers as well.

Next in line is Firefox 6, which will be released in about three months time.

Firefox 5 Gets Faster Connections, Up Next: Memory Improvements

Firefox 5 is a week away from being released as a final version. The browser is expected to be released as final on June 21. When you look at the changelog you will notice quite a few under the hood improvements that have not been talked about yet. HTTP Transactions sorted by CWND is one of those features. Most users probably wouldn’t associate a faster browser with that feature in particular, but the explanation on the Bugzilla site might change that.

What really distinguishes different connections to the same server is the size of the sending congestion window (CWND) on the server. If the window is large enough to support the next response document then it can all be transferred (by definition) in 1 RTT.

It basically means that Firefox may load resources faster if connection handling and priorities are changed.

I’ve done an experiment to show the best case – a link to a 25KB resource off of a page that contains a mixture of small and large content. In both cases the 25KB resource is loaded with an idle persistent connection. In the historic case it reuses a connection that had loaded a small image previously and it takes 3RTT (793ms) to transfer it.. in the case of sorting by cwnd the window is large enough to accommodate the entire resource and it is all complete in 1 RTT (363ms). Cool!

Even better, the worst case scenario is the status quo of Firefox 4. Users who are interested in a longer, more technical explanation, can visit the Bitsup blog for a taste of that.

Firefox 4 transfer

Firefox 5 transfer

The guys over at HTTPWatch have tested the new feature and found the “the performance benefit [to be] substantial”.

In other news: Firefox has a bad reputation for excessive memory usage, and related to this slow downs especially on startup or when closing the browser window. While that is certainly not the perception of all Firefox users, many perceive Firefox as a browser that uses to much memory.

The MemShrink project aims to optimize Firefox’s memory consumption. The developers list speed, stability and perception as the three core benefits of optimizing the memory usage of the Mozilla Firefox web browser.

The project members will analyze memory leak reports and prioritize them based on numbers of affected users and their default priority.

The developers have created a new website called Are We Slim Yet which tracks the process of cutting down on Firefox’s memory usage.

If things go forward as planned, we might see considerable memory footprint reductions in coming versions of the browser.
