If you are using Firefox 3.7 Alpha (properly Firefox 3.7a4 pre) and have been noticing your system slowing or choking, there are a few sub-processes or properly Out-of-process plug-ins (OOPP) that may be leaking memory. Active OOPPs will be listed in Windows Task Manager > Processes as mozilla-runtime.exe.
In my testing I found that three plug-ins
- Macromedia Shockwave for Director Netscape v10.1.1.16
- RealPlayer Version Plug-in 220.127.116.118
- RealPlayer G2 LiveConnect-enabled Plug-in (32-bit) 18.104.22.1680.
were guilty. Shockwave Flash would also run as an OOPP when you opened a Flash-enabled site. However once you done visiting such a site you can safely terminate this sub-process without messing up Firefox.
And if you haven’t used Firefox 3.7 Alpha yet, I hope you will test it soon. Instead of installing it use the latest Firefox 3.7 Alpha Portable edition. And make sure to allow it to update at least once a week instead of installing a copy.
Despite the odd version number, its way closer in features and spirit to the much-awaited Firefox 4. There are lost of improvements including an awesome page rendering speed, page rendering speed is awesome and this build despite its quirk is more polished than the official ‘n stable Firefox 3.6.x releases.
Windows 7 users will view the new clean interface with window transparency and Aero Peek support. If you use a previous version of Windows you may want to install the Strata 40 theme. To make sure you can install stuff on cutting edge versions, make sure to first install the Nightly Tester Tools extension. This let’s you bypass Firefox extension installer built-in version checking.
