Firefox Community Forum

Firefox has been running incredibly slow. I currently only have this window open, but if I open my task manger it shows 10 Firefox windows running. If I right click and end task, it will end the task, but shortly there after a new one will pop up. 1 of the is running in efficiency mode. I assume this is what is slowing down performance, but I do not know how to fix.

When trying to do a search for a video in YouTube Studio, the search seems to freeze. Doing a similar search in Microsoft Edge works OK. This problem started happening several months ago. I've tried clearing the cache for YouTube pages.
