Vydaná 31. máj 2025 - 102,21 kBFunguje s: firefox verzia 58.0 a novšia[v3.7.5 May 31st, 2025]
Enhanced Ad Experience: Your custom fast-forward/rewind buttons and keyboard shortcuts will now remain active and functional even when YouTube advertisements are playing.
Smart Ad Skipping: The fast-forward button and the right-arrow keyboard shortcut will now attempt to skip ads. This works by: Trying to click YouTube's native "Skip Ad" button if available. If no skip button is found, attempting to fast-forward the ad to its end.
Enhanced YouTube Navigation Stability: Resolved a bug where the extension's buttons and keyboard shortcuts could become unresponsive after navigating to a new video from a channel page or other internal YouTube links (improving behavior with YouTube's dynamic page loading).Zdrojový kód je k dispozícii v rámci licencie YouTube Fast Forward & Rewind License

Vydaná 24. máj 2025 - 101,77 kBFunguje s: firefox verzia 58.0 a novšia[v3.7.3 May 14th, 2025]Smoother Buttons: I've improved how the fast-forward and rewind buttons load on YouTube. They should now appear more smoothly when you start a video or click to a new one, with less of an abrupt "pop-in." This makes them feel more integrated with the player.
Code Organization: I've reorganized some of the extension's code "under the hood." I moved the styling rules for the popup settings window out of the popup.html file and into the main style.css file. This doesn't change how the popup looks to you, but it makes the code neater and easier for me to manage for future updates.
