FIrefox betrayed by its own "developers"? Memory Leak Work Around at Bottom
Firefox SUCKS memory and holds onto it. Try this test: Open it, leave ONE tab, open and sit back and and watch the damn thing crash.
Funny, as soon as the project people started getting so much money from Google that they had to restructure to avoid losing its non-profit status Firefox developed an insatiable thirst for RAM that has only gotten worse in the YEARS since. They won't fix the problem, they won't acknowledge the problem, the ignore every post about it . . . . So, is killing FF's user base the price for the continued Google money that they so quickly whored themselves out for? Has FF been run by Google these last few years? They certainly couldn't wreck any better.

"Using ADD-ons to remove memory leak. Mozilla says to remove add-ons to fix leak. Firefox sucks memory. it always has and always will. Nobody wants to admit it exsists on the Mozilla side must less fix it. Firewalls , etc do not cause the leak. You can remove all your ad-ons and leave firefox open and it will suck memory. Every tab you open drains your memory and continues to climb without opening any more. You can then close all your tabs and Firefox will not release the memory. Just fix it guys, it cant be that difficult "

"There is a way to stay on top of the memory usage:
Go to about:memory and scroll to the bottom. There are buttons there for garbage collection and minimizing memory usage. "

Lost this part somehow:
"BTW, they're conveniently at the top now. I added them to my homepage; maybe that will work"
Please try this two minute test.
Create a new Firefox profile
A new profile will have your system-installed plugins (e.g., Flash) and extensions (e.g., security suite toolbars), but no themes, other extensions, or other customizations. It also should have completely fresh settings databases and a fresh cache folder.
Exit Firefox and start up in the Profile Manager using Start > search box (or Run):
firefox.exe -P
Any time you want to switch profiles, exit Firefox and return to this dialog.
You'll click the Create Profile button. I recommend using the default location suggested, and to avoid data loss, not re-using any existing folder. Then start Firefox in the new profile you created.
What happens with memory usage with the two default tabs open, or another tab of your choice?
When returning to the Profile Manager, you might be tempted to use the Delete Profile button. But... it's a bit too easy to accidentally delete your "real" profile, so I recommend resisting the temptation. If you do want to clean up later, I suggest making a backup of all your profiles first in case something were to go wrong.
