This is becoming a very annoying issues anymore. When I have like anything over 10 tabs open FF makes windows go crazy and it locks up my entire PC.

      i have 2348 tabs open on my 8gb ram mac as well as uBlock Origin and it's running fine, I wouldn't bet on it.

      If you check task manager, what is the name of the processes hogging the most RAM? if it's FirefoxCP WebExtensions it may be your extensions.

      If the problem persists after reinstalling ublock then you can try resetting firefox to default settings:

      Unlikely, I've never had a problem with ublock but you could try removing it and reinstalling, make sure it's ublock origin from the official source
