Well since submitting this I find I can't surf either. I can only access firefox addresses. And practically every page I visit says if I have a problem the first thing I should do is 'refresh." You have got to be kidding. Please remove that suggestion it is what got me in this mess in the first place.

Update: now I can't close tabs either!

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

• Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
• Do NOT click the Reset button on the Safe Mode start window

• https://support.mozilla.org/kb/Safe+Mode
• https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes

Boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.
