I-Firefox Community Forum

I have removed Firefox and installed fresh the latest version 137.0.1 to address the issue of not being able to start a new tab or a new window. I am writing this from the initial window that opens when Firefox is launched. If I try to open a new tab it will hang with the blue circle displaying. If I click anywhere on the window if will grey out the background and display the error message :

Firefox is not responding

if you close the program, you might lose information

-> Close the program -> Wait for the program to respond

Tried waiting and it never comes back. Only option is to close the program. After that there is a message that is reporting the issue to Microsoft.

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.
