I love Firefox and Firebug, but Firefox seem to have some problem with the memory. Both mine and 2 co-workers at the office have the same problem - Firefox makes or PC/Vista or MacBook Pro sweat like a polarbear in Afrika.
Anyone else have this problem? And is there some solution for those of us who sell or kidneys before working without Firebug? :-)
I'd like to solve this because Firefox is one of the tools I use frequently when I code CSS, meaning I consider it programming/code-related.
I run firefox on vista/XP and a macbook pro regularly, and aside from taking a while longer than safari or chrome to start up, it's fine, and seems to use less RAM than either.
So the question is, what is wrong with your firefox? Do you have some broken extensions or something? Try deleting your firefox user profile (back it up first!) and see if the problem goes away. It lives in %APPDATA%\Mozilla\Firefox\Profiles.
Also, a "problem" that happens on the mac is if you load webpages with Adobe Flash in them. Adobe did a shoddy job on the mac port of flash and it uses way more CPU than the windows version, so that may be causing some of the problems.
