Bug 40024: Rip out remnants of Torbutton's internal version check
Since Tor Browser 9.0 (when the Onion Button was removed), Torbutton's
internal browser version check is no longer hooked up to any UI. But it
was still chugging along - making requests and logging to the Browser
Console.
Delete it, along with some now unnecessary support code.
