I'm not exactly sure what's going on with my browser, but it seems to be visiting Netflix-related websites as if I'm based in the US. I am, however, based in the UK. For example, heading to either netflix.co.uk or netflix.com just shows me the US catalogue. Also, whenever I try and visit websites that list what films are listed in each a Netflix region (e.g. http://netflix.maft.uk/catalogue), I get an error screen (see attached screenshot). However, I can visit other sites like Amazon and it'll correctly detect I'm in the UK. In the past I had proxy add-ons installed (like Hola!) in order to access other Netflix regions, but I uninstalled all these. Other browsers all work properly, so this is a Firefox issue. Any help would be much appreciated. Thank you!
