- So I found out what the issue is. I seemed to have gotten a piece of software installed on my computer called scorpion services. If you go into control panel and add remove programs you will see two things that are both related to this. Delete them, and than run a scan on your comp to make sure you did not miss anything. It seems this program is what is messing with the launcher, because as soon as I removed it my FF is working fine.

So there's a few things to try out, hope it helps.
