Add-On Problem?
After installing Windows 10 Enterprise, Firefox behaves well only in Safe Mode.
If I start it regularly, all of the text and icons on a page or even on a tab's label are "fuzzy."
I have tried disabling/turning off all extensions and plug-ins myself, but it still happens. If I start in Safe Mode, everything looks OK.

Type about:preferences#advanced<Enter> in the address bar. Under Advanced, Select General. Look for and turn off Use Hardware Acceleration.
Type about:addons<enter> in the address bar to open the Add-ons Manager. Hot key; <Control>(Mac=<Command>) <Shift> A)
On the left side of the page, select Appearance. Then select Default.
Now restart Firefox.

Thank you FredMcD!
Turning off 'Use Hardware Acceleration seems to have done the job.
