So, your Mozilla Firefox is not working, and you cant live without it?

This error usually happens on interrupted upgrades or power offs, the resolution is very easy you had to go to the program files folder, and after the mozilla folder.

And just delete the xpicleanup.dat file. That´s it.. No more troubles, finito…
And you can enjoy the best browser…
