Hi All,

Every time I go onto any website I get this: http://gyazo.com/918da196e05ea2220c54b7c23b37e688

I really can't work out the problem. It's only on Firefox and I've been having to use Chrome lately. I'm a web developer and I need my tools/add-ons from Firefox. I've tried reinstalling Firefox and removed all files beforehand. I also tried running it in safe mode and I've tried to flush my DNS and I've also tried it on another computer where Firefox works fine. It's just here. I've been using Firefox for over 7 years and I've never had this before.

Any help is greatly appreciated.

Thanks!
