Topic title covers most of it.
A few days ago, Firefox started running extremely slowly. Tabs take considerably longer to load, the browser becomes laggy when it tries to load anything, and attempting to open multiple tabs at once leads to Firefox becoming completely unresponsive for some time.
Attempting to refresh had no effect. Safe mode made it run at full speed, but disabling all add-ons did nothing under normal circumstances. Disabling hardware acceleration caused Firefox to go from "unusable" to "frustratingly slow". Disabling WebGL had no appreciable effect. Installing new drivers for my processor and graphics card had no effect. Restarting my computer had no effect. Removing cookies had no effect. Clearing the cache had no effect. Disabling Sync had no effect. Reinstalling Firefox by renaming the old install to "Old Firefox" had no effect.
I'm using Firefox 46.0.1, 64 bit.
I can't provide info on my plugins right now, as I'm posting this in Chrome because of how slow Firefox has become.
