I recently installed version Firefox 3.6.16 and 4.0 on a few machines. I find it starts out using about 120 MB of RAM. This grows to anywhere in the range of 175 MB to 250 MB within an hour or so. This happens both on Windows XP 32-bit and Windows 7 64-bit machines. It also happens in Firefox Safe mode, which seems to suggest it is Firefox and not the add-ons or extensions.
This seems excessive. Firefox also slows down with the increased memory consumption. The users rarely have more than about five tabs open.
I've seen an untested (by Mozilla) add-on called Memory Fox that promises to reduce memory consumption.
* Is this memory usage abnormal in your experience?
* Do you have any suggestions for reducing it?
* Do you have any knowledge and recommendations regarding Memory Fox?
