Hi all,
Here's a site with everything you wanted to know about Firefox 2.0.0.11 and includes some advanced tweaks and instructions on how to implement them.
WWW Link I tweaked past versions of FF but haven't done any of these ones yet because this new version is running well.
This site is pretty long and in depth but I found the 'Advanced Tweaking pages, 6, 7, & 8 most informative. Hope some of you find this helpful. Check for '*Create' entries in about:config where these entries are not included by default and have to be created in about:config. I thought the browser.cache.memory.capacity entry might help some of the memory leak problems I've heard about.
Happy FF tweaking,
Cheers,
