What is your computer system and Firefox?


Open the Norton program and have it check for updates. Do the same with the computer system.


Type about:addons<enter> in the address bar to open your Add-ons Manager. Hot key; <Control>(Mac=<Command>)<Shift> A)

In the Add-ons Manager, on the left, select Extensions. For now, disable Norton.

Boot the computer in Windows Safe mode with network support to see if that has effect in case security software is causing problems.
