I've always been able to share pages with the Firefox "Share this Page" icon. The last week or so, I've not been able to share pages to Twitter, though. I just get a message saying Firefox can't connect to Twitter at this time. I have removed Twitter from the add-on, and then re-added it several times, to no avail. I have disabled it and then enabled it several times, as well. I have no problem tweeting or sharing tweets from the actual article I'm trying to share - the problem only exists with the Share this Page add-on in Firefox. I'm using Firefox version 46.0.1. I'm just befuddled as to how to fix this. Help!
