Did Mozilla Fix The Memory Leaks With Firefox 1.5.0.2

Mozilla has officially released Firefox 1.5.0.2 today and it is actually quite exciting. I have been using this build for a little over a month (since it was a Tinderbox build) and the memory leaks seem to be minimal compared to Firefox 1.5.0.1! With having a constant 8 or so tabs open I normally max out at 60-70MB, and this is the case on multiple computers! Yay Firefox!




There are some other things that I follow to help minimize Firefox’s memory usage, such as the list of extensions with memory leaks or a tweak to save some RAM when you minimize Firefox. I currently only use the Tab Mix Plus extension because that seems to solve all my needs and the additional RAM usage is minimal (even with the built-in SessionSaver features).

For those of you that didn’t look at the build date on Firefox 1.5.0.2 you will notice that it is March 8, 2006 which is just one day after I posted my article on the ‘release’ of 1.5.0.2! At that time it was just a Tinderbox build, but often times these builds do not get changed much just like in this case. Here is the list of changes for this build:


Firefox 1.5.0.2 provides native support for Macintosh with Intel Core processors, and stability and security enhancements that are part of our ongoing program to provide a safer Internet experience for our users. We recommend that all Firefox users upgrade to this latest version.

Here’s what’s new in Firefox 1.5.0.2:

  • Universal Binary support for Mac OS X which provides native support for Macintosh with Intel Core processors. Firefox supports the enhancements to performance introduced by the new MacIntel chipsets.
  • Improvements to product stability.
  • Several security fixes.

There are many links listed below. You can download the regular Firefox 1.5.0.2 or there is also a portable version that I put together for this build. There is also release notes if you want to see the nitty gritty on the new build.

For those people that want the portable verison, all you have to do is download the Portable Firefox 1.5.0.2 file below. Then you unzip the file and browse for the file PortableFirefox.exe. Just execute that file and you will be running Portable Firefox 1.5.0.2! It may be more convenient if you make a shortcut to PortableFirefox.exe and place it on your Desktop or in your Start Menu.

I hope everyone enjoys this release because it appears that Mozilla did a really good job on it. I can’t wait for Firefox 2.0 Alpha 2 on May 9th!
