This morning, after I did an update for Mozilla, two things are creating problems. 1. When I open a page, and want to exit, when I click on the X in the upper right corner, nothing happens, To close a page, I have to click on the X on the tab. 2. All videos on my Face Book page, whether in timeline or otherwise, will not play. When I click on the Play button, a new window opens, full page, with the right pointing play arrow. When I click on it, all it does is recycle back to the beginning. Had no problems prior to the update. Can someone tell me how to fix this. If not, I'll uninstall Firefox and go back to IE.
