Experimental Features

ok thanks, everything looks normal there so i'd recommend a clean reinstall:

• download the full firefox setup file from https://www.mozilla.org/firefox/all/
• uninstall firefox through the windows control panel
• manually delete any remaining files in the firefox program folder, which usually resides in C:\Program Files (x86)\Mozilla Firefox\
• reinstall firefox

That worked, thank you very much!! I had reinstalled before trying to correct, but did not do the "clean" install. All is good now.
