Is Firefox Becoming a Memory Hog?

Over the past few weeks, Firefox has automatically downloaded several upgrades to my PC. At this time, I am on version 2.0.0.11, which seems to use an inordinate amount of memory. For example, with only one pane open, the browser requires 88MB of RAM.

Has anyone else noticed this?

Thanks,

Roy

I have the same version, and just one copy open with just one window browsing to google.com, mine was using about 46 megs

I also have the following installed:
ColorZilla 1.0
Firebug 1.05
FlashGot 0.6.9.3
Image Zoom 0.3
MeasureIt 0.3.6
Password Exporter 1.0.6
UnPlug 1.6.06
Web Developer 1.1.4

Yes, I have also noticed that firefox is taking up more and more RAM with each release. Not to mention creeping file size.

However, I found that memory usage is also to do with the sites you visit.

It became a memory hog quite some time ago. There's a problem where Firefox caches far more Web pages than required, the Mozilla devs said it's a feature, whilst the community argued it's a memory leak. So there was a huge flameware for several years. Smiling

It's being fixed now, you can look forward to a much leaner memory footprint in Firefox 3. Naturally Opera beats everything in terms of speed and memory usage (might have some competition from Safari though). Wink

That makes sense. Sometimes after I've shut down Firefox completely, I check in the Windows Task Manager, and it will show Firefox still running.

Actually, that's what Task Manager shows, after I've just opened Firefox. However, after a few hours, the memory use increases considerably, even after I've opened and closed several different panes. It's as if the browser is keeping something else open as well, or running some additional process behind the scenes.

OK. I am now viewing this page through Opera 9.24 and Task Manager reads just 28,690K of RAM being used. I'll test this out for a few days.

I haven't noticed this issue before, but looks like firefox uses to much ram indeed. I got 127mb used now:(

I've known about this before, but no problem for me since I do use a lot of plugins. And yes FF had the memory leak problem long ago up until today. But I have resolved this issue by occasionally closing down firefox and then restart it... (I do however open about 15 tabs simultaneously almost all the time)...

Yes, this is an issue with Firefox 2 and they are denying it exists. However, having said that, this has been fixed in Firefox 3 Wink

haha, i think it is a bit of a memory hog, mine sometimes runs up to 75 megs, but that is not enough to make me stop using it, also I always have at least 5 to 6 tabs open

I have recently added some more plugins and now GMail runs slower. I searched on this and it so happens that the Firebug extension is responsible for this. It just so happens that I use firebug quite often so i'm going to have to put up with it.

Would disabling Firebug for the GMail domain help with the speed problem? Am pretty sure it can be disabled for certain domains.

On a seperate note Firefox 3 is in Beta now, apparently it has been somewhat slimlined.
