Extreme memory-hog on Firefox 3.6.6

English Applications

Hi!
I just installed OS11.3 64bits with Firefox 3.6.6

I see an extreme memory-hog after only a day running.
Now Firefox har been running for 4hours and is using over 800MB and growing with only one page up(Lotus iNotes Web-mail).

I mostly use Opera web-browser (10.70 Beta) and have 4 page up and it only use 600MB stable.

If Firefox is running for 24hours the memory-usage will pass 2GB by doing nothing and OS begin to feel slow.
This happens after last upgrade of Firefox.

Anyone else that see this?

I sitt and look at System Monitor! Firefox is using 1MB more each minute and is counting :-S
