I've been extremely frustrated the last few days, as since the day I updated to FF40 I've had problems with the Twitter web app, TweetDeck. There are errors in the site which may or may not be caused by something on their end or an updated feature on FF40's end. Basically, there are some JS functions that are being called that aren't working. There's also a warning that appears several times that SHA-1 isn't the best encryption. Here are the errors I get in the console: JQMIGRATE: Logging is active default.0712cf5a58.js:5:12874 e.after/<@https://ton.twimg.com/tweetdeck-web/web/scripts/swift/app/main.084897b117.js:1:7818
