How can I revert to an earlier, less memory-hungry version?

I get an "excessive memory usage" warning every time I use the computer --and it points to Firefox needing 405 meg to run; other warnings have said 700+ megs.

Hi ejoeblow,

Have you looked at the Knowledge Base article Firefox uses too much memory or CPU resources - How to fix or Firefox uses too much memory or CPU resources - How to fix? There is a lot of great information in there.

If you still want to roll back to a previous version of Firefox, just take a look at the Knowledge Base article Install an older version of Firefox.

Hopefully this helps!
