I downloaded Firefox a while ago then never used it. I uninstalled too. Then today I decided I wanted to use Firefox so I installed it again. Only I cant remember ever setting a user name or any password. It sometimes asks for a master password too which I have no idea what it could me. Whats my best course of action?

Firefox doesn't use a password to start or use it.

The Master Password locks the Password Manager. https://support.mozilla.org/en-US/search?esab=a&w=1&q=Master%20Password

What is your homepage? That may be asking for a password. Are you using a proxy?

Are you using Sync?

Create a new profile to test if your current profile is causing the problem.

See "Creating a profile":

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.
