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

I tried the following: Start Firefox in Safe Mode | Refresh Firefox | Uninstalled/reinstalled Firefox | Uninstalled Flash Player

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.
