How to troubleshoot script errors, slow speeds and unresponsive FF

more options

On a daily basis I get these errors: A web page is slowing your browser - Server not found - Firefox not responding - Stop script or continue

None of these worked. I have 2 plugins installed but set to Never Activate.

Although I uninstalled Flash Player, I still see it in my files. See screenshot

If there is a pattern of particular sites causing problems, that may be useful to know. There's also this general article: Quick fixes if your Firefox slows down.

But for right now: have you considered reducing the amount of stuff Firefox loads/processes by using an ad blocker or tracking blocker? These are some popular choices:
