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.

Firefox 3 Solves the Memory Problems?

This is a ‘bit of news that might have been missed by some. It looks like Firefox 3 continues to gain praise for having a significant reduction in the amount of memory it uses over Firefox 2.

Over at Ars Technica this is what they are saying:

During intensive browsing with approximately 50 tabs, I have found that Firefox 3 generally consumes less than half of the memory used by Firefox 2.0.0.12. Firefox 3 is also snappier and more responsive when switching between tabs and performing other operations that typically lag in Firefox 2.0.0.12 when the browser is experiencing heavy load.

This is great news for any Firefox fans out there. Over the recent years the memory problems seem to be the big sticking point for a lot of people. Has this mountain of an issue finally been solved?

Firefox 3 Beta 4 in the Wild

Firefox 3 Beta 4 is ready for download. Well there was some confusion yesterday on if it was out or not, so I decided to hold off on this till today. Yet again, Mozilla continues to surprise and amaze with improvements to the core product. Two of the biggest updates I would say would be:

  • Speed:
    Improvements to our JavaScript engine as well as profile guided optimizations have resulted in significant improvements. Compared to Firefox 2, web applications like Google Mail and Zoho Office run twice as fast in Firefox 3 Beta 4, and the popular SunSpider test from Apple shows improvements over previous releases.
  • Memory usage:
    Some new technologies work together to reduce the amount of memory used by Firefox 3 Beta 4 over a web browsing session. Memory cycles are broken and collected by an automated cycle collector, a new memory allocator reduces fragmentation, hundreds of leaks have been fixed, and caching strategies have been tuned.

You can check out the full list of improvements and updates on the release notes and as always, Mozilla Links has an awesome in-depth review of this newest Firefox beta release.

Firefox 3 – More Beta 2 Goodies

Firefox 3 Beta 2 just rolled out and I have to say things just keep looking better and better. I mean, I’m not really all that disappointed with Firefox now but with what is being done there are tons of improvements on the way.

This recent release includes approximately 900 improvements over the previous beta, including fixes for stability, performance, memory usage, platform enhancements and user interface improvements. Awesome news all around.

Here are a few more details worth mentioning:

Star button: quickly add bookmarks from the location bar with a single click; a second click lets you file and tag them.

Places Organizer: view, organize and search through all of your bookmarks, tags, and browsing history with multiple views and smart folders to store your frequent searches.

New Download Manager: the revised download manager makes it much easier to locate downloaded files, and displays where a file came from.

Are we we excited yet? How about the news that 300 individual memory leaks have been plugged, and a new XPCOM cycle collector completely eliminates many more.

Fix for Firefox Memory Problems?

firefoxlogo.jpg Firefox uses a lot of RAM. It is the number one complaint about this otherwise awesome web browser. So what can you do to solve this issue? Well there are a few rumored fixed out there in the wild.

Here is the nitty-gritty about:config solution to the problem:

  • Open up about:config by typing it into your Firefox address bar.
  • Right-click, go to new and then integer and name it this: browser.cache.memory.capacity
  • For the integer value, enter in 15000 if you have 512MB to 1GB of RAM. For those with less (between 128MB to 512MB), try a value of 5000.  You’re done!

Then all you should need to restart Firefox for it to take effect.
