;__;

I did something regrettable earlier. I set a master password for firefox. And now I can't get it right. >__<

It was something along the lines of "I can't believe that this isn't butter!11". Unfortunately, I don't remember if "can't" was a contraction or "can not", as with "isn't". I'm also reasonably sure that the word "really" was somewhere in there too. With all the possibilites for wording, I don't think I'll be figuring out the password anytime soon.

So my question is: Will a simple re-install of Firefox fix the problem? Is there anything I can do, really? (Aside from never making passwords like this again.)

Wouldn't hurt to try, not like theres another option unless theres a way to take off the password without remembering it, but that would ruin the point of the password to begin with.

You don't need to reinstall, you need FIREMASTER™.

It runs from a command prompt, and bruteforces your Firefox password.
It will also crack non-alphanumeric passwords, so it should work fine for you.
