Every Firefox action works, but brings up a window saying "A javascript error has occurred."

for several months now, every Firefox action works but brings up an error message, "A Java script error has occurred." I cancel out the error messages (two identical error messages show up each time) and Firefox continues to work normally.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
