Watching a CNN video on YouTube Firefox suddenly freezes and does not accept any further actions. Even shutting down it will block the process and I need to use the "Shut down anyway" function. Similarly, Thunderbird will lock up in the middle of writing a response, but here it is just the window and I lose what I typed, but I can go back and push "reply" again and retype the answer. Whether these are down to similar issues I don't know. Obviously, this sounds like a graphics driver, so I made sure all updates are installed and there is no further update available for both, Firefox and Thunderbird as well as the system drivers.

Any pointer is appreciated as this is really annoying. Thanks
