About this extension

This is a tiny addon that evolved from my userscript.
It simply updates your URL when you're watching a YouTube or a Twitch video so that it always contains a timecode at the position you're watching the video.

This makes it a bit simpler to share videos with timecodes, but the main reason is to store the position at which you stopped watching the video in the browser history.

You may look into addon preferences for the offset - by default it is -1 so the timecode lags behind the actual video for one second, it can be any number - even positive if that is needed for whatever reason. Also the preferences allow you to specify the timecode format - there are two interchangeable formats supported by both YouTube and Twitch at the moment.

Addon icon was made by Freepik from www.flaticon.com

Developer comments

This addon requires history permissions and access data for youtube and twitch sites.

History permission is needed for the workaround where it removed excess history items, so that URL changes do not clutter the history - this addon actually uses the 'history.replaceState' call which should not clutter history by itself, but Firefox has a long-standing bug of this not being the case.

Access data is because the addon subscribes to video time updates on the video page and updates the URL accordingly. It does not access ANY data except video time.

Release notes for 1.3.0

Fixed addon not working with dynamically added video tags - such as when you open a YouTube video in the current tab instead of opening it in the new one. This is a big fix actually.
