FireFox: does it have a memory leak?

FF has been pretty sluggish lately and then i pulled up the task manager and noticed it was using 190MB of ram??? for having one page up?? i am not near peaked ram wise but it is running slow....any ideas?

and this is just a basic install of FF - i haven't installed any addition to it all...
 
And how does memory usage change over time if:
you do nothing?
you surf around then return to just the single page open?
 
I've noticed the same problem. I'm getting pretty sick of FF's lousy performance, but I just don't like using IE7 very much either 🙁
 
i shut it down and now it is @ 45MB . i will leave it open and see what happens, but everytime i have it open, it always gets sluggish and ram usage is always high after i browse for some time. i don't know if it is trying to keep pages cached in the ram?

It is probably doing some caching. However, it shouldn't be making FF sluggish (unless you're totally out of system RAM). You can disable caching or change the maximum size under Tools->Options...->Advanced->Network (...not sure why it's under 'Network', but it is).

Is there a particular page that seems to be using a lot of memory when it's open? Some Flash animations or complex JavaScript entities can eat up a lot of memory (usually due to a programming error).

i still have 1.4-1.5GB of free ram - had ps, illustrator open and some other background stuff and then FF. my machine runs fine and is quick but FF slows down to the point that sometimes when i am typing i am typing much faster than what is showing up on screen. this only happens in FF and seems to be getting worse as they put out new updates. i think i have ~15days set to save content and use up to 50MB of disk space for cache - hell it could use 50MB of ram if it wanted to, but i found this under privacy, not advanced...i am running 1.50.11, but just looked and see there is a V 2.0.0.3...i have hit "check for updates" and it comes back ok. is V 2.x a beta version? maybe this is the problem - running an old version?
 
now it is back to 70MB since the last re-start...???

and mathias99 - the pages are not heavy in flash or java, usually google, some specialty forums, cnn, fox, weather, google mail, yahoo...that's about it

2.X is the 'new' FF. They're still maintaining 1.X, but I don't think it's getting all the new updates or quite as much attention. I'd upgrade unless you have some pressing reason to still be using the old one. You need to explicitly download the new v2.0 client; 1.X won't auto-update to 2.X (so that people who do need to stick with 1.X for some reason can still use auto-update).

Also, with the way FF works internally -- memory usages of 75+MB for 'normal' browsing (especially with lots of tabs open) don't necessarily indicate anything wrong. I've definitely seen FF get affected by what I assume are poorly-written flash or JS-based ads; maybe try using an ad blocker plugin and see if it fixes the issue?

Opera ftw!

No Stumble Upon for Opera (that I know of) 🙁

I like Opera. The addons are what make me stick with Firefox.
 
7 tabs open with 7 different websites in ff, 42mb usage... cause i don't have any addons installed, not even flash, i found most of them poorly written, even Flash player, either that or websites use too many flash ads. the big downside is of course very inconvenient on many websites
 
well updated to 2.x (whatever the newest version is) and that damn thing crashes a lot. at least 3-4x/day 🙁
 
24 tabs 150mb
course i've had it go up to 350mb with just a few more tabs open...sometimes less, depends on the pages i guess. i also have 2gb
 
now at 199mb 23 tabs😛 go figure. its caching is based on your ram, so it might be grabbing more at the start?
