This ext has become soo useful over time, indispensable even.
Thx Dr. N for updating so it works again! 😄

works again, and is absolutely indispensible.

It went down today following the recent firefox update

rly good work, thx for update!
without it I felt blind on YouTube ;-)

Thanks for the update, now works perfectly on Firefox again.

Thank you for the update!

youtube watchmaker stopped working, but found a solution for me,, firefox,, updated my k-lite codec pack, and weeeee,,best addon by far,, tanx snikluas

Finally it has been updated and working again!, thank you!

Love the extension - extremely useful, but as of last Windows update, no longer working?

Exactly what I needed. Really clearly labels watched vids. Import from ff history and youtube then good to go. So good, i'm going to see if I can throw a donation at the author

This extension is great because you never click on a video that you have already seen. One thing that is not true is that it only works with the new YouTube user interface. Since YouTube changed the user interface, I've been using the YouTube Redux extension to get the old user interface back. I just don't like the fact that the comments are now on the right and there are suggestions for other videos below the video. The Watchmaker extension works perfectly with the YouTube Redux extension and everything runs smoothly, and I haven't noticed any problems. The YouTube Redux extension forces the previous user interface.

Great stuff!

Could you add support for shorts as well?

Works fantastic

It marks clearly watched videos. It's easy to export and import watched videos from a browser to another.

I can't even remember what Youtube is like without this addon. Incredible work.

One of my favorite add-ons on YouTube. I watch 100s of videos weekly and this helps me out a lot in tracking what I've seen and what I haven't. really fantastic add-on!!
