Several weeks ago I started getting a message saying "Firefox is unable to connect to Twitter." At least one upgrade later, it's still saying the same thing. I've tried everything I can think of. I've even "refreshed" Firefox (never again!). I've disabled everything, reenabled it. Uninstalled it, reinstalled it. I'm now down to basics only and it still doesn't work. And now, since the upgrade to 47.0, Facebook share doesn't work, either. Either I get some extra page that says "data" something or other, or if I am able to share one page, then that's the page that will keep coming up to share forevermore, regardless of the page I actually do want to share. And yes, I have cleared my cache, cookies, history, etc., in an attempt to fix it. I used to use Firefox share all the time with no problems - and all without ever clearing cache, cookies, history, etc. I'm befuddled. A friend of mine said it has something to do with the way the code is written and it's an internal Mozilla problem that isn't being addressed. Anyone else having the same problem? Anyone have a solution? I really miss the share button!
