After Firefox 17 installed itself I began having problems with some web site graphics not loading properly such as Wikipedia and Facebook. It is hard to describe without showing a picture but if it happened to you as well you will know what I mean.
Go to Solution.
Update back up to Firefox 17 (using older versions is very insecure) and then read Websites look wrong or appear differently than they should
I have Moz Backup so it is not to dangerous. None of those topics seems to fit and I already tried some of them to no avail
Yes it is dangerous, as Firefox 12 has dozens of known security holes that are being publicly exploited. Did you even try updating and trying the steps in the article?
I reinstalled 17 and that fixed the problem for now. Thanks!
