This extension updates a youtube video's URL to include the "t=" parameter with wherever you currently are in the video.
This could be useful when a youtube video is stalled and you want to easily reload the page without losing your place, or when firefox crashes or restarts or updates.
Unfortunately I couldn't find a way for it not to spam the browser history with a new entry every second. This is apparently a long-running issue with browsers and history.replaceState(). I hope this isn't a dealbreaker.
Does the same thing as this other chrome plugin of the same name, to which this has no relation:
