Firefox 3.6 tweaks

Problem?: I was happily using the features of Firefox 3.5 and below, then changing to 3.6 somehow changed some of my favorite features.....

Why can't my firefox work on Windows 64 bit OS??

There has been widespread reports on problematic memory issues with Firefox 3.* on Windows 64-bit systems, but the problem doesn't seem to occur for every system.

Here's the link to get our good old Firefox in pure 64bit versions. Note that it doesn't run on 32bit Windows even if your hardware supports it.
