I have not noticed that, However I noticed that it keeps crashing I will monitor memory usage from now.

Yup. Mine hit ~850Mb on friday. Now this can happen when I've been working across a lot of WebUIs but in this case there were only 3-4 tabs active. Closing and reopening with the same sessions dropped it to ~350.

I haven't used it yet, and based on the limited feedback I've received I should stay away. Apparently the interface has changed a lot and isn't liked much. This just ends the debate.

I don't mind the interface so much, I kinda like it. But it crashes all the time.

Check your add-ons. There are quite a few add-ons that worked fine with 3 but kill 4 with their memory usage such as McAfee's SiteAdvisor. It's always best to just run Firefox with the bare minimum of extensions and plug-ins that you need but a lot of people just pile on the stuff until it's unstable because they don't know otherwise.

Under what O/S? I did not notice any problems with it when I loaded it on Ubuntu 10.10. It likes to crash randomly on Ubuntu 11.04 though. I always have a lot of browsers open with several tabs each, so its memory usage is always on the high side for me.

A little off-topic but I have found that Firefox 4 tends to freeze up when clearing history (under Windows 7.)

No real issues here on my Mac. It just works (har har har).

Actually the only real thing that might be an issue is my Java plugin giving me fits every so often.

Firefox was always memory hungry if you ask me, not just since FF4

IE is too. But some of that is just my usage. Having 3-5 windows open with 3-6 tabs each is a lot. Especially if you leave these open over night or two, it can cripple a system.

About the only thing that "just works"...

Firefox 5 seems to be significantly better. Very snappy browser too but most of my add-ons are now disabled due to compatibility check though none of them were anything that you would consider to be essential to daily use.

No problems here. The FF4 Beta crashed a lot for me but the later RCs and actual release of FF4 has been fine.

Just to update this, I left the browser open for over a day with over a dozen tabs open and it's sitting at around 700 MB of memory usage at this time. Not bad but still pretty funky.

I'm just guessing on this, but perhaps memory usage is dependent on how much RAM you have on your system. Mine has been staying around 1/2 GB (~450-500K in Task Manager); I have several tabs open. The number of and what add-ons you have, number of tabs/windows open, etc can all affect memory usage. The hardware acceleration may also affect it, but idk.

I do love Firefox though. The memory usage for me doesn't affect the other applications that I have running. I love the customization, speed, interface, and all that also.
