I only had one issue today with the update and it was my fault I have a part time habit of clicking on things I notice I clicked all the PT icon down in the right corner today and somehow my twitter became a blank white page.
What I did was close out of FF run CCleaner that didn't do anything I logged out and back in still nothing then I clicked the settings icon bottom right clicked clear cache and clicked Authenticate and is now working.
Maybe this will help someone else.
