How to troubleshoot script errors, slow speeds and unresponsive FF
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

These could be part of the same set of symptoms, or they might be unrelated.
- A web page is slowing your browser + Stop script or continue. As a starting point, see: Warning Unresponsive script - What it means and how to fix it
- Server not found. Does this persist after a reload? or if you reload (using the button in the address bar or Ctrl+r) does the page load?
- Firefox not responding. As a starting point, see: Firefox hangs or is not responding - How to fix.
Regarding Flash, as long as it is set to Never Activate in Firefox, I don't think you have to worry about the leftover files.
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.
Ive tried all suggestions above and nothing has changed. What else can I do?
I really need to solve this soon.

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:
