Good afternoon, I have been trying to figure out a reason to why my firefox web browser keeps jumbling into a slanted page and blurred type when I roll my mouse over anything. I have upgraded the software and reset it twice, turned off and on my computer multiple times. And every time I re-open firefox the slanting page begins. My initial thought was that our internet was down. But that seems not to be true. Then I thought I had a virus, but I work on a mac, so I don't know what else to do. Do you have any solutions I could try to use to fix this problem. I have a screen shot if you need a visual of the problem.

Let me know if you need any other information. Thank you and I hope you can help. :)
