Can't get to Charter.net email, videos won't run
Yesterday morning all was fine until the Update manager indicated I lacked several updates. After loading them I could no longer get to my Charter.net email nor could I see videos (youtube, embedded in news websites, etc.)
I have Firefox as the browser. I am new to both Firefox and Ubuntu and am getting the hang of it but this is not a user error nor is the Charter.net email system down (I can get to it on a friend's windows system).
How do I restore my system to yesterday morning without having to try typing code? I thinking 'point/click' type of actions are more my speed.
