In firefox most of my clickable button links appear as strange little boxes with numbers in them (see the screenshot). They still function normally but just don't appear as they should. I tried to disable the "no script" add on and change some browser settings but nothing works. My chrome doesn't have this problem so it's only an issue with firefox. Also many videos don't work. They do on youtube, and similar websites but not on yahoo, or veehd(divx) etc. I don't know if these issues are related. Huge thanks if anyone can help.
