On desktop version of Tor, I want to change the user agent in the configuration, just to be able to visit mobile sites. If it's safe, could you tell me how to choose One? (It seems I can choose general.useragent.override, but when I choose it and hit enter, nothing happens.)
Sorry, safe against ... I don't even know, but when I go to about:config, it gives me a warning "you could void warranty = conpromise security?"
