I seem to be having a lot of problems with my Firefox install. One of these is that it uses a lot of memory, but I'm not sure if it's normal or not.
After a few hours of browsing it can go up to 800MB of RAM. I watch a fair amount of videos on youtube and play the occasional Flash game. In combination with the "plugin-containers" it can even reach 1.1-1.2GB of RAM.
I'm using Waterfox, a 64bit mod of Firefox 7, but even when using Firefox 4 I've had this issue. It runs on a 64bit Windows 7 PC.
I usually have 3-5 tabs open, sometimes up to 10. But once i close those, it'll still use about the same amount of memory. Installed plug-ins are only Greasemonkey and Downloadhelper.
Is this normal or not? Can I do anything about it?
