Here is something I have never ran into, for some reason suddenly today, I am only able to load about half the websites I try to load. A blank page loads that says "Hmm we're having trouble finding that site". But the tab says "Server not found". Again it's only some pages that won't load. It does not matter if I click the bookmark, or type in the address,it's always the same pages every time. I tried 19 sites, (10 bookmarks, and 9 typed), plus typing in some of the bookmarks also. If I change over to Chrome, or any other browser those pages will load. If I use Firefox Mobile, those pages load. Something has gotten messed up in my PC settings, or something. I have tried clearing the cache, the history, and the cookies, no luck. I restarted into safe mode, and had the same problem. It's been forever since I had any problems with FIrefox, and must admit I have forgotten most of the troubleshooting tips, that I used to know. But I did remember those, unfortunately none of those are the problem. What else can I try? Thanks in advance. BTW: I am submitting this on my phone because this is one site that won't load. If it did I would, I would click the "Share Data" button.
