Firefox problems


For some reason Firefox, which I have been using for a very long time in my development work without any problems, to day told me that I should reset Firefox.

Now Firefox is not working at all anymore. Just as an example, the page looks like this when I try to access How do I fix that and get Firefox "back on track"?

This message always received from google server whenever browser does not connect to through secure channel which is HTTPS.
 It allows web servers to declare that web browsers i.e. firefox and others should only interact with it using secure HTTPS connections, and never via the insecure HTTP protocol.
just try google with other browser.

I have reinstalled and refreshed several times. Same result.
This is not a problem with Google's sites. It does the same with Mozilla's own pages and all other pages:
