I didn't catch anything wrong with your configuration, but have you tried to see if a addon is causing a issue in Firefox Safe Mode?

SEE: Diagnose Firefox issues using Troubleshoot Mode

Thank you. It works in safe mode. When I reset FF to factory do I lose all my logins, bookmarks and auto forms?

If you reset it keeps, passwords, bookmarks, etc.

OMG. It worked. Thank you so much.

If it happens again:

If you use extensions (Firefox/Tools > Add-ons > Extensions) that can block content (e.g. Adblock Plus, NoScript, Flash Block, Ghostery) then make sure that such extensions aren't blocking content.

If it works in Safe Mode and in normal mode with all extensions (Firefox/Tools > Add-ons > Extensions) disabled then try to find which extension is causing it by enabling one extension at a time until the problem reappears.

Close and restart Firefox after each change via "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: Firefox > Quit Firefox; Linux: Firefox/File > Quit)

OMG, thanks so much for this info. I've had problems so many times with Flash updates and Firefox I can't believe how simple this was to solve.
