Firefox does not load websites right.
I have Firefox the last version. My Antivirus Avast (Free)
I have these problems with my Firefox, sometimes the website does not load right. This happens mainly in ebay, hotmail, and some other websites.
I uploaded a picture of it, after this happens I need to refresh the website 1 or 2 times, in order to see it normal.
I scanned my computer, but no virus. Somebody said a spyware could be the problem, but my computer (AV) does not detect any.
I wonder what the problem could be
I hope someone can help me, thank you!
