New Unpatched Firefox Flaw

There is a new unpatched memory corruption flaw in the latest version of Firefox.  What this means is that hackers could drop malware onto vulnerable systems.

Chances are this will be fixed sooner, rather than later – here is a little more about the story from The Register:

Security notification firm Secunia reports that the security bug (which it describes as extremely critical) stems from errors in handling JavaScript code. The flaw has been confirmed in the latest 3.5 version of Firefox, released in late June.

Older versions of the popular alternative browser might also be affected, Secunia warns.

Exploit code has been uploaded onto recently revived security exploit website milw0rm, a factor that could hasten the development of more attack code.

Secunia advises Firefox users to avoid browsing untrusted websites or following untrusted links pending the availability of a fix from Mozilla (there’s nothing in the pipeline just yet).

Best advice I can give to you is to browse safely, don’t go to web sites you don’t trust, and be sure to keep your security programs up to date.

UPDATE:

Found this via Mashable:

Until Mozilla addresses this vulnerability, here’s a temporary fix: Type about:config in Firefox address bar, and set “javascript.options.jit.content” to “false.”

So there is your fix for now.  Thanks to everybody who sent this in!

UPDATE #2:

This problem was fixed in Firefox 3.5.1, so the above hack from Mashable is no longer needed.  To check for updates, be sure to go to Help > “Check for Updates…” in Firefox.

Speed Up Firefox 3.5 Start up Times on Windows

Speed up Start Times in Firefox 3.5 Does it seem that Firefox 3.5 is a little sluggish when it starts on your Windows-powered machine?

Due to some unknown reason, Firefox on Windows pulls certain file locations for security reasons.  In turn, having too many temporary, history or recent document files will slow down Firefox 3.5’s data generation process.  A bug has been filed about this, but in the mean time – the best thing you can do to help fix it is to do a little house cleaning.

The fix here is to browse through and clear both Internet Explorer’s history and cache and Firefox’s history and cache as much as you can.  You can find more help with this process at these resources:

I had not noticed this problem too much – then again, I have my Firefox temp files set to clear every time I close the browser and I hardly ever use Internet Explorer.  How about you?

UPDATE:

This problem was fixed in Firefox 3.5.1.  To check for updates, be sure to go to Help > “Check for Updates…” in Firefox.  Thanks to the Firefox development team for the speedy update!

Firefox Turns Deviously Green

new green theme for firefox There are not many green themes for Firefox that I would consider using – however Devious Green might be one of the few I add to my list of themes you have to at least try – if you love browsing in the shade of money, grass and ummm… other green things.

The theme is based off the look and feel of the web site DeviantART – and pulls off it’s style very well.  One place where some might have problems is the icons are a little jagged – because, they are on DeviantART’s web site too.  As the author says, “Toolbar icons are in the DA .gif emoticon styles, jagged edges on purpose, so please don’t complain about that.”

You can pick up the Devious Green theme for Firefox via the Firefox add-ons site.

Disable and Undo Tab Tearing in Firefox 3.5

Disable Tab Tearing in Firefox 3.5 One of the new features coming to Firefox 3.5 was tab tearing.  What has become a nuisance for some, it lets you drag a tab outside of Firefox and launch in a new window.  I kind of like the feature, however if you do not – there is an add-on that will help sooth your pain.

You will want to pickup the bug489729 add-on for Firefox.  This oddly named extension comes with two main controls. You can:

  • Disable Detach Tab – use this to disable tab tearing
  • Enable Drop URL – use this to be able to drag a tab to your desktop to create a shortcut.

Now, what if you want to keep tab tearing, however you would like the ability to undo a tab detachment?  Then you need to pick up the Undo Detach Tab add-on for Firefox.  As the name says, it will add a context menu option where you can undo your tab tearing.

Hide the Tab Bar When Only One Page is Open

Turn off "Always show the tab bar" in Firefox 3.5

When your only looking at one single page in Firefox 3.5, for some reason – they still show you the tab bar.  If you would like to disable this feature, it is an easy thing to do.

Via the contact page, I got asked an interesting question.  How can you make Firefox hide the tab bar in Firefox 3.5 when you only have one page open?  From within Firefox, go to Tools, and then Options.  Now, got to the Tabs menu, and un-check the “Always show the tab bar” selection, and hit the OK button.

By default, Firefox 3.5 has this feature turned on – however if you want to have it go back to hiding the tab bar each time you only have one tab open, now you have an easy way to fix it. 

10 Popular Themes That Are Firefox 3.5 Ready

One of the negative side effects of a new version of Firefox rolling out is the fact that some Firefox theme creators neglect to update their themes to the newest versions.  So, when updating our browser, that leaves some of us in the dark, when it comes to using the themes we know and love.  However, this time around many more popular themes have been updated to support Firefox 3.5 and here are my favorite ten for you to choose from.

Love (or Disable) the New Tab Button

New Tab Button in Firefox

Love it, or hate it – Firefox got one more addition to it’s browser that seems to have gotten a mixed reaction from the fans. The open new tab button rests at the end of your tab bar in Firefox 3.5 giving you an easier user interface to open a new tab.

Clicking on the little “+” icon at the end of your open tabs, opens a new tab.  Seems simple enough, and I do like the fact that it gives one more clean way for new users to instantly figure it out.

How do I remove the new tab button? Well, if you are handy with editing your userChrome.css file – this should be an easy customization to put in place.  Just add this line:

.tabs-newtab-button {display: none;}

To edit your userChrome.css file, you must first locate it inside of your profile folder.  Depending on your operating system of choice, that location might differ.  Check out “where is my Firefox profile folder?” for more information.

So how do you feel, love the new icon or is it in your way?

Make HTML 5 Videos Go Full Screen

Full Screen HTML 5 Videos The talk about Firefox 3.5 supporting the HTML 5 support for playing videos without the need of a player was pretty sweet.  Seeing it in action, now that I have Firefox 3.5 installed is even sweeter.  You know what would put the icing on the cake?  If I could make those videos go to full screen resolutions.

The Full Screen Video add-on for Firefox does that.  Once installed, it adds a “Full Screen” menu option, when you right-click on any HTML5 powered video.  As of right now the only two known issues with this awesome extension are:

  • When switching to full screen, the video will load and play from the start.
  • Full screen is really only implemented on Windows at this point. On other operating systems, it’s merely a maximized window.

Other than that Full Screen Video gives you a simple addition to an already awesome feature of Firefox.  You can pickup this add-on via the Firefox Add-ons web site or check out the official web site for more information on the project.

Firefox Private Browsing Mode Help and FAQ

Private Browsing Mode in Firefox

Want to increase your privacy on your PC?  With the release of Firefox 3.5, our favorite browser now has a Private Browsing mode.  Usually your browser remembers the web sites you have visited, your user names and passwords, your browsing history and more.  However, with this newest addition to the Firefox 3.5 feature list, you can now go incognito on the Internet.

To turn on Private Browsing mode, go to Tools (in the menu bar) and then select Start Private Browsing.  You will then get a popup menu asking you if you would really like to start Private Browsing mode.  Hit the “Start Private Browsing” button to continue.

To be able to tell that you are in Private Browsing mode, the Firefox window title will show (Private Browsing) after the page title you are looking at.  When you are privately browsing, the browser will not remember:

  • Visited pages
  • Form and Search Bar entries
  • Passwords
  • Download List entries
  • Cookies
  • Cached files

If you create a new bookmark while in Private Browsing mode, you will keep it after turning Private Browsing mode off.  Also, if you save or download any files to your PC, those files will not be removed when you stop Private Browsing mode either (they will not though show up in the Downloads window).

To turn Private Browsing mode off, you will want to click on Tools in the menu bar, and the select Stop Private Browsing.  To confirm you have done this correctly, check the Firefox window’s title bar to make sure (Private Browsing) is no longer showing.

Quickly Turn Private Browsing On (or Off)

One tweak or suggestion for this new mode is to give the user a toolbar button to turn it on or off.  The Toggle Private Browsing add-on for Firefox does that.  It gives you the ability to switch between private browsing and regular browsing by adding a button to either the toolbar or status bar.

Private Browsing in Firefox I hope that helps when it comes to learning the basics about the Private Browsing mode in Firefox.  How do you like it thus far, and how do you think this benefits the browser?
