Hi all, Every day for the past month or two, Firefox has been gradually using up memory until my computer freezes and I have to restart the program. I'll admit I can have 80 or 90 tabs open sometimes, but using chrome on my laptop this really isn't a problem in the way of memory. Firefox on the other hand will gradually open more processes and use up to 11gb of memory before I have to close it. I've checked the built-in performance graph (image attached) and it doesn't show any of my tabs using anywhere near that amount of memory. However, when I open the Windows Task Manager (image also attached) Firefox is using a baffling amount of system resources. I can't simply close a few tabs, either. If I close all but three tabs the memory usage will hardly drop, only when I fully restart the program does it return to a 'normal' state for a while. Would appreciate any help anybody can provide. Thanks.
