I am one of that users that surt the web during too many hours, and i've noticed, after opening and closing lots of tabs, and especially, new windows, Firefox eats too much GDI resources, and even it does not free an ammout of it. For example: browse during 3-4 hours, open some windows, and you will get 40-45% of GDI heap (or even less, <30%) free, EVEN WITHOUT RUNNING ANOTHER APPLICATIONS!. Close Firefox, and GDI heap will return only to 50-55% (normal free GDI on my system is ~70-75%). And there are not only GDI resources waste, some times, when opening pages on tabs or new windows after some hours results in slowdowns, and Firefox locks by 2-3 seconds, with 95% of CPU usage. I see a BIG memory leak, especially with the GDI heap
I have the same problem running: Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0 with 512Mb RAM on Win98Se (IE6 updates installed) I can run my resources down by simply refreshing a webpage with a lot of flash content such as macromedia's page or some game pages. Once the resources drop to less than 50% the system gets unstable and FF either crashes or if I manage to close it down and restart it, the resrouces do not come back up to 80%+, often just 55%. A reboot is needed to clear it up. Somestimes the system won't reboot and crashes then.
