FF4 however seems to have no difference between hardware and software mode so no effect, just 23FPS on 20 fish not worth trying 1000 :)

I've not got FF4 installed to test on my computer but the latest Nightly (6.0a1) build I'm running manages 60FPS on FishIE Tank from settings 1 - 100 after going to 250 it drops to approx. 45-50FPS, this is with HW Acceleration enabled though, without it it's pretty sluggish, so yeah, what I'm saying is HWA does make a massive difference in these builds :)

Getting 60 fps for 1000 on my machine. It's awesome to watch FWIW

I don;t get the bashin. FF runs great on all of my machine.s I occasionaly use chrome, but FF is my main browser for work and play,

ok I got ff5b2 running alongside ff4

same tabs loaded in each both no plugins/addons.

after approx 9 hours uptime

ff5 start usage - 224 meg
ff5 current usage - 538 meg
ff4 start usage - 275 meg
ff4 current usage - 1224meg (1.2gig)

both are leaking memory, ff5 just seems more contained as if they partially fixed the problem. If they partially fixed it then it suggests they know the problem exists in ff4 and continue to distribute it as a stable version.

here is a link of 100s of users.
Firefox 4, ok... memory leak? More like hemorrhage... | Firefox Support Forum | Firefox Help
many more at other posts on same site.

bartab has little affect as the memory leak is not on site data, it seems to be related to the display, if I do any of the following the usage goes down.

refresh focused tab, yep simply refreshing the tab in the foreground, doesnt matter which tab I have in the foreground all same behaviour will recover the memory.
open a new tab.
close current tab.

it seems basically doing some sort of activity recovers the memory so if I were to guess they have made GC not run at all when idle and as a result memory can go out of control, users who dont leave their pc's or firefox running for long periods of time idle probably wont notice this issue. Given that FF3 has problems with excessive GC causing the app to become unresponsive especially on flash videos then I will guess they reduced when GC is run to mitigate that problem (rather than doing proper fix making GC its own process) and as a result memory usage is not maintained when idle. My guess in FF5 they either changed something to reduce the rate memory is leaking or they have made GC more agressive than in FF4.
