FireFox 4 and RAM usage

[Bateluer]

I pretty much leave FF open all the time, with multiple tabs open 24/7. RAM usage in FF has always been a bit on the high side, but its never really bothered me as my desktop has 8GB of RAM. But I've been noticing a lot of text lag, delay between my hitting the key and when it shows up in the browser. While looking into something else, I happened to have Task Manager up last night. The Firefox process was using 2.4GB of RAM. WTF!? I only had a few tabs open, AT, XDA, the Phoenix ComiCon site, Homedepot.com, nothing fancy. I closed it out completely, and restarted it and it dropped to ~200MB with my usual tabs.

Just looked now, and its at 1.4GB RAM usage. Are there serious memory leaks in FF4 or is it just that crappy?

Chrome doesn't quite have all the extensions/addons I have in FireFox yet, so I can't exactly switch browsers.

I was getting some bad memory leaks with the earlier Minefield builds, and it seemed confined to one or 2 sites, but I never tracked it down. It's been fine for me running the latest Minefield, as well as Firefox proper. I suspected Flash was the issue. Make sure that's updated, as well as any addons that interact with the webpage.

Mozilla usually blames Firefox memory leaks on bad extensions.

Firefox does have memory leaks, but that sounds a bit more severe than most.

I used to do that, leave FF open all of the time, and accumulated 100s of tabs across multiple windows, eventually I hit the per-process memory limit of 2GB of virtual memory, and the app crashed. Or I would run out of GDI resources, and stuff would stop redrawing properly.

Some of the anti-Facebook extensions I wanted are on Chrome now, so I'm test driving that. Shame though, I like FireFox 4. Maybe I'll uninstall it, wipe all directories, caches, etc, and reinstall.

Just make a new profile?

I still have memory leak issues on OS X, but not on Windows (even with the latest Firefox 4 version). Which OS are you on?
