...Firefox's insatiable memory appetite...

I'm not sure I see that. I've had Firefox 2.0.0.1 running continuously now for about 4 weeks on my 64-bit Gentoo system, I currently have 6 windows and 11 tabs open, and it's using about 360MiB of RAM. Is that bad?

Oh my, yes (IMHO)... Mine's been running close to 9 weeks, has 4 regular windows open (closed two or three earlier today) plus the bookmark manager, has a total of 9 tabs, and it's using 100MB (RSS). I consider even that rather hefty, though I've definitely seen worse. (A Netscape 4.x instance hit 950MB once... That was after running for 4-6 months, but still--it wasn't a pretty sight, particularly when it locked up. NN4 never liked big tables...)

Btw, I have a parallel instance of Moz 1.7.10 running: same uptime, 3 windows + bookmark mangler, 8 tabs, 65MB (RSS). That's much more reasonable, but then again, I don't work it quite as hard, either.

That's impossible! On my 64 bit system running 2.0.0.1 it only takes me about 1/2 day of browsing to hit 900 MB. If I forget to kill & restart Firefox every few hours (thank goodness for session saving), my machine goes into deep swap and I have to either wait 20 minutes for the OOM killer to save me or punch the reset button.

And, once it cruises past 600 MB, Firefox gets unbelievably slow. Click on a tab, wait for 1 second of 100% CPU before it responds, stuff like that. I don't know what's different between your 2.0.0.1 and mine, ldo, but I envy you.

I wonder if it has to do with the types of sites one visits.

Do you have nspluginwrapper installed to enable the Adobe Flash plug-in? When I did, my Firefox would only run for a couple of days at a time before I started incurring major disk thrashing and slowness. Since I removed nspluginwrapper, Firefox has stayed up non-stop. At least 4 weeks, like I said.

Darn--there doesn't seem to be any easy way to get the exact date and time my Firefox process started--all ps is showing is "2006" ...

Heh...I had the same problem initially, but I found you can use either -o bsdstart or -o start=WIDE-START-COLUMN to get the day and month, at least.
