Add-on summary

Sample Use Case ‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾ Suppose a YouTube video is an album of 5 songs and you only want to listen to the 1st and the 3rd songs in it. Using this extension, you can specify the intervals (ranges) of those songs, and only those portions will be played.

Specifying Multiple Intervals ‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾ An input box appears just below the video. There, you should specify the intervals as a comma separated list. Example: "00:00-00:30, 5:00-5:30" (without quotes) specifies two intervals, namely, the first 30 seconds and then the 30 seconds after the 5-minute mark. On clicking 'Apply', these intervals are played one after another.

To make it easier to specify the intervals, two buttons 'Start' and 'End' are provided. This is how you should use them: Click 'Start' at time xx:xx. Then click 'End' at time yy:yy. This will automatically copy the interval "xx:xx - yy:yy" into the input box. Repeat this to add several intervals.

Bookmarking ‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾ You can also 'bookmark' the intervals that you have just applied (by clicking the 'Bookmark!' button). Next time you play the same video, those intervals are automatically loaded from bookmarks and only the corresponding portions are played. You can use this feature to essentially create a whole playlist of video segments (by first creating the playlist on YouTube, and then bookmarking the desired portions for individual videos in it).

Clicking the button 'All B.s' opens up a side pane where all the previously bookmarked interval lists are shown. If there are multiple lists for the same video, then the most recently added interval-list will load automatically. Here, you can also manually delete a bookmark.

I've been waiting years for a video bookmarks extension for FF, and this is exactly what I've been looking for, with one exception - I'm looking for one that works on any HTML5 video, not just YouTube. I don't suppose that it could be modified to support HTML5 video across the board, could it? IDK what all it would entail, but I ask because the Chrome extension that first introduced me to the video bookmarking concept (called Video Bookmarks Controller. Technically, Video Speed Controller was my first intro, but it only allows 1 non-persistent "jump to" marker per video, which is great but limited), ultimately leading to my complete dependence on it 😂 was also created specifically with YouTube in mind and to this day still has a few extra features/perks exclusive to YT, but at some point the developer added support for any video site using HTML5. Your extension and it are very similar. In fact, without having used yours extensively yet, the only pronounced difference I spot is that you utilize local device storage while it uses a dedicated site/server that also allows for managing the saved bookmarks hosted there. Anyway, obviously you should do what you wish, but I'd be beyond appreciative if you did something similar with this add-on, i.e., chose to add support for any HTML5 video.

This is incredibly useful for learning guitar and better than the chrome equivalent. Thank you!
