Firefox extensions spiking CPU and hanging browser
Firefox extensions stopped working for me tonight. If I click on any in the toolbar the little triangle appears but not the extension's actual menu. And the browser is hanging, not loading anything.
Also there is a huge cpu spike for the WebExtensions process. If I kill it, suddenly the web pages that were hanging start to load.
I'm using Firefox 79.0 on Ubuntu.

Thanks for the pointer in the right direction. After doing what you recommended, though, I would fall back into the corrupted state whenever I installed uBlock Origin.
After doing a Firefox refresh, everything works.
Well done. Contact uBlock support for more help. Please keep us posted.
