Hello, each time firefox is updated, the browser language is reset to English, despite the fact that each time it is manually configured to Russian (my native language). Though, in windows my language is also set to Russian. With each update of firefox, I have to go into the settings, select "find and add language", search my Russian language in the list, and select it. Every time, until a new firefox update. p.s. Search engine keywords are also reset by default every update. Example: for Wikipedia i set keyword "wi", and every firefox update it resets to nothing.
