Watchmarker for Youtube Extension

Youtube keeps track of your watch history and automatically marks videos that you have already watched. They however only mark recently seen videos, which is kind of disappointing. This addon fixes this issue and keeps track of your entire watch history, such that not only the recently seen videos are being marked.

***Does this work with the old Youtube theme?*** I am afraid that only the new theme is supported. If you do not know which theme you are currently using then it is very likely the new one.

***How can the persistence of the database be ensured?*** There is an export and import feature, which makes it easy to create a backup of the history. This backup can easily be archived such that you can ensure that you never lose your history.

***How can I make sure that the database is complete?*** The automatic synchronization only considers the recent activity. You are thus encouraged to manually initiate a complete synchronization in the settings, which incorporates as much of your history as possible.

***Something is broken, I demand a fix!*** Please be considerate when leaving a review, this is a free extension that I invest my spare time in. If there is something that does not work then please file an issue on Github where it is easier for me to track.

Martin Wagoner (ID: 000000c053cd9195) Voted 4 ★ - Updated 11/15/2024 I really like this extension, and think everyone should download it. The only problem I've noticed is that sometimes the synchronization doesn't get the watch order correct. For example, one Let's Play that I have is shown as having been watched in the order of episode 60, followed by episodes 59, 63, 62, 61. It's not a big issue, especially considering it's listed correctly on the YouTube history page, but it does make me a little annoyed when stuff is out of order like that. And there is no way to delete multiple entries at once, only individually. Maybe adding the ability to manually move the videos around after they've been logged to fix this. Still download it, and you won't regret it.

Gaurav (ID: 0000003c0036ea0b) Voted 5 ★ - Updated 10/12/2023 I love that the watch-date can be appended on the thumbnail text now. As long as this remains good enough to track 99% of watches across different history sources, I very much appreciate this feature update. One nice to have would probably be able to sort the list column-wise in the extension details, and perhaps filter by month/year etc.

Andario Andrada (ID: 00000022605068a7) Voted 1 ★ - Updated 10/11/2023 Easily one of my FAVORITE addons, but you totally screwd it with today´s update. As such, my latest database entry says July 2023, even though I´ve watched HUNDREDS of videos ever since, all of them GONE, including the ones I watched yesterday. Please let me know if there´s any way for you to fix this, or I should try to revert to the latest version, because it´s truly a catastrophe, for me. I´ll update the rating as soon as you let us know. Thanks.
