Thanks guys! I simply deleted the whole ~/.mozilla directory, which seemed to do the trick for me. Now I'm running desktop-effects as normal and haven't experienced the bug since. This is what I did:
1) export firefox bookmarks
2) quit firefox
3) go to the home directory and delete the ~/.mozilla directory (don't worry, firefox recreates it later)
