Fixes
- Fixed a startup issue that prevented the skipper from running on supported video sites
- Fixed skipping on ad formats where the ad is stitched directly into the video stream
- Skip requests no longer depend on a single button style, so skipping keeps working when YouTube updates its player

Improvements
- Ads on YouTube are now muted and fast-forwarded so they finish in about a second, even when no skip button is offered
- Playback speed and sound settings are restored automatically the moment an ad ends
- Better detection of the newest YouTube skip button designs, with a smart fallback that finds the button by its label
