Hi. I recently noticed this problem, but don't know why it's happening. When I visit certain websites, the language of that particular site gets changed. For example, I visited the Spotify site yesterday, and the language was changed to Swedish. This isn't to do with my IP; that's reported correctly, and the language in the Preferences panel is also set as it should be. I've also checked the general.useragent setting in the about:config dialog, which is also correct. Does anyone have any ideas as to why this could be happening? I've tried this with a portable installation of FF, and the pages display as they should. I've also tested them in IE. Thanks. Elliott.
