I have gotten "Unable to connect. An error occurred during a connection" error message on EVERY. SINGLE. WEBSITE.
This problem started just last night. Other browsers work, my internet works, I have used everything on this support website to try to fix the problem and NOTHING has worked. I have even refreshed and completely reinstalled Firefox and that hasn't worked either. What can I do? I can't even take a screenshot, ask for help, or load back into my Firefox account!

What version of Firefox? What OS?
There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.

Some problems occur when your Internet security program was set to trust the previous version of Firefox, but no longer recognizes your updated version as trusted. Now how to fix the problem: To allow Firefox to connect to the Internet again;
- Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
- Remove Firefox from your program's list of trusted or recognized programs. For detailed instructions, see
