The apparent source of my Firefox memory bloat problems
I recently took another shot at trying to get rid of my long-running Firefox performance problems, which I had narrowed down to garbage collection stalls resulting from memory bloat. The good news is that I seem to have found what was causing my memory problems. The bad news is that it's in extensions that I more or less care about.
(While I haven't seen memory bloat with Status-4-Evar, having it active seems to make Firefox's scrolling somewhat less snappy for me. Without GreaseMoneky and Stylish, the status bar is relatively empty anyways so I've currently experimenting with disabling S4E.)
Although I called GreaseMonkey and Stylish essential extensions back here, I can in practice live without them. Having mangled Google search results and various badly formatted websites irritates me, but I can sort of live with them (and the cure for the latter is to stop visiting those websites). I wish I didn't have to, so I keep hoping that Firefox will come up with a better solution for whatever is causing these leaks.
