Firefox uses all my memory with 30/40 tabs open but only reads 200mb total in about:performance
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.

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or userChrome.css is causing the problem.
- switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
- do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window
