I'm trying to reduce firefox memory usage. Even though I have 4gb of ram I still would like to reduce firefox's usage. I did a few tweaks but it does not look like they work on the latest firefox versions anymore because they had no effect.

what is your average memory usage at any given time and also how many extensions do you have and how many tabs open at any given time?

I have 9 tabs open, using 113 megs. I'm not sure about extensions? I have google toolbar though.

firefox does love memory,the more you have the more it wants,also having excess plugins can increase it also java can increase it and you dont need the google toolbar as you already have google in firefox,also is it the newest version?

Firefox is known to have some memory leak problems anyway...

Only reason I have google toolbar is for autofill, other wise I would use the built in search. Theres tons of memory leak fix tricks, I just wanted to know what someone is using on the latest ver of firefox.

Minimize your tab usage and enabled extensions could help memory a bit.

RAM is designed to be used.
You have 2 Gigs of ram so no need to complain, with just windows running an firefox you still probably have over 60% of your ram free anyway.

FF is a must for me, even if its memory management system is a very ****.
The only solution I have found is the extension "Restart Firefox". On a 512Mb ram pc, it is able to free even 200Mb at a time.

Look for and download Firefox Ultimate Optimizer. Keeps Firefox running at a cool 10mb for me.

Disable useless plugins, i bet that is the problem

He has 4GB, which is even sillier.

Anyway, if you really want to lower memory usage, enable the trim_on_minimize setting, it will slow it down but reduce memory, which is all anybody seems to care about.

If you have 4 gig RAM then there isnt much point of reducing Firefox memory usage if its only about 113MB unless your using the rest of your RAM.

Normally, my firefox uses about 150M of memory, and I use a very handy extension StatusbarEx to monitor the memory usage, it can display the memory firefox used, and the system memory available in the status bar.

So when I notify that the memory firefox used beyond, say, 200M, I just restart it, hope this could be useful :-)

Does that really make it down to 10MB or does it fake it? Ive had my system running at 20MB according to task manager even though the real usage was 1.4GB but that only happens when programs use too much memory.
