It could be in your registry as there is a wack of Mozilla entries in there to be cleaned out when you rip Firefox out and try to go fresh. If you are comfortable working in the registry I would uninstall and clean that up as best you can then reboot. Then re-install.

Also there was a big Windows 10 update today that I got so make sure you have rebooted regardless.

As well today there was a major interruption with more sites down do to a new round of ransomware. Fedex was down today for 1 day 2 hours ago Last Down: that is not at all clear...it was down, now yesterday about the time you posted.

I would say clear the cache and dump your cookies but if deleted the folders under c:/users/local/apdata/mozilla then you have.

Plug along with us and let us know what is going on, best to make it in point form if multiple issues. Thanks

Well did the above this morning. Worked fine for a few hours. Then got the insecure connection junk all over again. Closed and reopened FF still have the problem. Reboot the computer and had it working for 5 minutes then insecure connection on any website all over again. I'm at a loss here. I have no idea what keeps causing this issue other then I know FF updated before all this started happening and it wasn't doing this prior to the update.

On the insecure connection page, can you find an Advanced button? That usually reveals more detailed information about the problem including a CODE in all caps separated with _ characters. If you could copy/paste that section into a reply, it may help get to the bottom of it.

One of the most common codes is covered by this article: How to troubleshoot security error codes on secure websites. Does that help?

Also, since Firefox shouldn't develop connection issues at random, could you scan for common malware problems? Our support article lists free cleaners (completely free or free trial) users have found helpful: Troubleshoot Firefox issues caused by malware. Since they have different lists and techniques, you probably should run several of them.

There was an advanced button but was unhelpful. There was some error and because of frustration I neglected to copy the error.

Now something new I'm trying is not connectng to the windscribe vpn firefox plugin but still staying connected to the actual windscripe app. So far so good. When I signed out of the plugin the pages started loading again without ff refresh so hopefully that was the issue. Although doesn't explain why it was happening in the first place.

Please let us know if this solved your issue or if need further assistance.

Seems to be fixed as I haven't been having any other problems.
