Received the following complaint:

I was talking about working set memory on Twitter. Firefox 4 is using 774MB tonight, with no more heavy use than I put Firefox 3 under and never saw this kind of usage after half a day.

That's after running since 8am, with no more than 5 tabs running at a time. Mostly from Newsvine.com (regular posting and interaction), Gmail (as an "app" tab), and a few other transient tabs (HuffPost, NYTimes, Google News, etc).

If you'd like more detailed information, let me know what you need and I'll get it.

The current profile is not new, it was created when I built this machine on 2009-06-26. Whatever the latest version of Firefox 3 was on that date, that's the version that created this profile.

Here's the output of about:memory:

It's lower than the 700MB+ that it was a few hours ago because I restarted the browser, but it's only been running three hours.

If you'd like me to disable any or all of those extensions and see what happens, I'd be happy to. Just let me know.
