Release notes for 3.16.0
  • Rework for more standardized fetch calls with better error checking. Should prevent errors and fix potential issues with ratings not appearing
  • Firefox now uses sync storage instead of local, allowing for settings to be stored with your Firefox account if enabled. Existing settings will be converted on update. (FYI FF android does not sync with your account. This is a FF limitation, not he add-on)
  • Adjustments to WikiData date query which should allow it to always respond, as it was not working in all scenarios.
  • Adjusted the WikiData calls to be able to lookup using the Letterboxd, IMDb, and TMDB IDs all at once. While I did not find a scenario where just one was not finding a match, this should theoretically allow for improved matching.
  • Fixed issue with Metacritic critic scores actually pulling one critic's rating when no average is available yet.
  • Fixed issue with Metacritic tooltip when rating is tbd.
