That’s a hell of alot of ram usage on just firefox, the most mine has every used is around 150-200mb of ram which i can live with.

I see the user is running Firefox in Windows. We all know that Windows is kinda lacking when it comes to memory management, so rather than jumping to conclusions that Firefox is at fault. We must consider it could be a Windows memory management issue.

Next, the user does not complain of any problems such as slow operation or a low memory error. He only complains that Task Manager is reporting that Firefox is using 910,525KB of memory…. so what! Idle memory in a computer is of no use. I think a lot of users read these numbers and do not understand what they mean or how memory works.

It seems to me that firefox just leaks ram continuously. AFAIK, it’s ALWAYS done that. It’s never been a problem for me; because, as you said, I just close and re-open firefox whenever it becomes a problem (which is rare). I put a custom re-start button on the toolbar just for that purpose; so it automatically re-opens the pages I was viewing.

But… but… but… FF3 is supposed to be SOOO much better than FF2! Not.

FF3 might use 20% less memory to open two tabs on simple websites, but it still leaks like a sieve. After an hours of use I frequently see it using 400 MB of RAM after closing all the tabs. The leaks use up 50 MB to 80 MB even after quitting the program and going into and back out of Hibernation to try and clear out the crap.

And two years after the first reports of problems they *STILL* have not fixed the Download Manager freezing if you let it get too many items.

How about disabling your add-ons first to see how Firefox itself is using memory?

I’ve been using FF3 for months now and have never had memory issues but then I also don’t load up add-ons either. I think I have 2 or 3 running like PDF download and forecaster but that’s it. There’s little need for many others and if you want to run them then memory is the price.

FF3 is definitely better at memory management because I used to see FF2 just gobble it up by the hour…

FF3 works fine for me…I still think you need to check your extensions first then try some of the well-know tweaks for memory and network management (if they are needed) and then determine the cause…

just my 02

how many tabs did you open

Ehm… he’s probably using FF2 instead of FF3. Get real and install FF3!

I’ve never had that problem with Firefox. But then again I’ve been using third party memory management utilities for years (mainly Cacheman).

Non-issue on Ubuntu. No probs with ff2, and now still no probs with ff3.

Short of widespread reports of this problem, I’m inclined to think it’s something to do with the way this computer is set up, not inherently with firefox.

Personally, I find my firefox memory leaks have pretty much gone away with FF3; and I’m very bad for running firefox for a week or more with ridculous numbers of tabs open and constant reloads as I develop and test websites. If FF3 had a serious memory leak problem, I’d probably be the first one to notice.

Mind you I have very few plug-ins installed, a couple of web development things and one or two others.

I have the same problem. Try deleting the Skype Extension.

ditto on the Skype extension.. after I installed the Skype extension, FF started using around 35-40% CPU, and the Mem usage continually increases from 500m to over 1G, then drops down to 500 again.
After disabling the Skype extension, it stopped doing it.

Aye, Skype extension seemed to make to problem even worse, with it installed, RAM usage was up to 1.5G.

After removing it stays steady under 200k with all the crapons and tabs I normally used open.
