Fixes YouTube scrobbling on Firefox. Since Firefox 153, the check that asks YouTube Music whether a video is music was failing on every video, and the extension treated that failure as "this isn't music" — silently blocking every YouTube scrobble. The check now runs from the extension's background script, an unreachable check no longer blocks scrobbling, and videos YouTube itself categorises as Music are always scrobbled. The "Scrobble only videos recognized by YouTube Music" setting is also visible in options again.

New in 3.20.7
• Sign in with Google — you can now scrobble without a Hive account or
Keychain. Just sign in with Google at scrobble.life and your listening
history saves to your profile.
• Settings → Accounts now shows your Google sign-in (and shows both if you
also connect Hive Keychain).

v3.20.6
• Better music-vs-video detection on YouTube. Videos that YouTube itself recognizes as music recordings — including official audio / "art
tracks" and re-uploads on channels that aren't VEVO — are now scrobbled as music instead of being miscounted as video.
