Many users seem to have the feeling that the memory consumption of Firefox seems to get out of hand after a certain period of continued web browsing. It is however not that easy to determine the exact cause that seems to slow down Firefox after a while. I try to give some insights in possible solutions to those slow downs - they might help in some cases but could change nothing in others.
The first and most important aspect is to consider removing themes and extensions which can really consume lots of memory. Before you start removing extensions you should do the following to see if it is possible to determine which extension or theme is responsible for the memory consumption.
All the following tweaks can be achieved by typing in about:config in the Firefox address bar and entering (part of) the bolded parameter into the filter field.
Update: Mozilla has improved the browser's memory consumption significantly in newer versions. The preferences are however all still working.
