Hi #Twitter, this âbrowserâ is the current Thunderbird release, a mail and RSS client. Its capabilities are no different from Firefox 78. How about you detect Gecko rather than detecting Firefox?
Better yet, do feature detection instead of UA sniffing: https://developer.mozilla.org/en-US/docs/Web/HTTP/Browser_detection_using_the_user_agent

Just realized that the Twitter server responds with â400 Bad Requestâ here. Thatâs IMHO a very unconventional way of saying: âYour request is fine but I donât like the client you are using.â
