Hi, I've had a problem for about a year now where Firefox takes up too much physical memory. Recently it's been getting so bad that my RAM (6GB) usage is at 95% or higher and the freezing and lagging from Firefox gets so bad that I can't even close the program properly... I heard recent news that an add-on extension I had was to blame for this, and now that I've gotten rid of it, it should be better, right? Well, it isn't; and I even looked at my about:memory. As it turns out: vsize, resident, private, and heap-mapped are taking up over 1000MB each. Any way I can reduce this? notes: I've already tried "Minimize memory usage". the browser crashed for ten minutes to do this and it went down by about 200k, but it was momentary. It's still building memory.
