"FIrefox Account"! How do I permanently change language?
How do I change the language for the Firefox Account pages (Monitor, Sync etc.)?
I am not asking about changing the default language for the webpages! Living in Germany I had to set locale Germany, but I did set the language to English. But oddly it would display all Ff's account pages in German..
There is a solution from a previous problem which I assume is the problem you are encountering.
