Why am I asked for a password when trying to use about;config, where is the password set and can I change/delete this?
I tried to use about:config, but I was asked for a password. I don't remember entering a password and have never used the master password function. Where has this come from, and how can I change the password or get rid of the need for a password?

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
- Don't make any changes on the Safe mode start window.

Thanks cor-el. You were correct; it was a password protected extension trying to prevent any changes. I have deleted the extension and everything works fine now
