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

The addon is OK overall.
But recent update required a new "Block content on any page" permission. I can't understand, why it's needed?
It'd be nice from the developer to at least add explanation for each permission in the description. This is a common practice for addons.

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!

Unfortunately, the viewing date for many videos is set to the date of installation of the extension. Secondly, if you enter a word in the YouTube history search, the viewing dates of all the videos that appear in the search will be updated to the current date, even if they were viewed 10 years ago.

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

Honestly it more often doesn't work than it does.
as of today it adds videos I didn't watch to watched list. I deleted the video with app refreshed and it shows i just watched it (a minute ago) when i didn't

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

As of 2/4/25 it's currently not marking videos on the main youtube page as watched even if I've watched them. It's working on the subscription page and in search.

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 concept, but ultimately too many false positives for watched videos, even after adjusting the settings a few times. An in-browser "mark un-played" button would be helpful, as it is removing play marks from a text-only list is more work than it's worth for me.

Edit to add: Actually an option to have the extension mark a video as played only when the progress bar hits a certain threshold (100%, 95%, etc) would be ideal

Great stuff!

Could you add support for shorts as well?

Works fantastic
