Update causes freeze.

I updated sometime around last Sunday and noticed a different look on Firefox. Also the screen settings seemed different. Does Magea automatically resize my setting if it doesn't like them?
I am running Privacy Badger, Ghostery and Noscript.
My problem now is that if I manage to find a site that Firefox doesn't like, the whole system freezes. I have to pull the plug on it if I want immediate action. Ctrl+Q is inert.
Also when I reboot, every update since my installation shows up on the screen. That's been happening since I can recall. Similarly when I reboot. I also have to catch the memory check, can't seem to find out how to switch that off in BIOS.
Any help will be appreciated.
