I use Firefox as my default broswer i have extensions enabled not sure if one is causing the problem i will be addressing. When I am in Facebook i often get a yellow script bar across the top in the address bar that says a script error on the page that says temporarily dis able stop it or wait > i hve disabled most if not all my extensions. have run Firefox in safe mode and still get it. I get it mostly in Facebook. Some one mentioned that perhaps the extension Font contrast may be doing it. I lile this extension because it darkens the font and makes it readable. I have not found any other extension that do this. Is there a way to remove or disable this script bar
