Simple and easy. Works as expected.

Works like a charm! Thank you!

I have tried everything I can think of for changing the accept-language of Firefox, but it seems to be stuck on en-GB. I've changed the locale of my system to en-US but Firefox still sends out en-GB. I tried your addon to fix it and it still wont change. I will be willing to give higher marks if you can show that your addon is fine and that it's something else.

Yeah your addon is just fine I think. I'm blaming this one on MOZILLA FF. the addon wasn't changing anything in the accept-language field until I changed "en-US,en" to just "en-US"

FF is kinda shoddy like that.
