Help with Javascript Error


I already made about 4 games, all which work fine, but recently I started a new one. When I want I try to open with Firefox, it says Javascript error. Whats wrong?


I just changed the title of the thread to be a little less misleading.
If there’s no additional detail given could you post a screenshot of the error?


Thanks and I dont need any help, I fixed it.
