With features like export and import, Watchmarker for Youtube ensures your watch history database is safely backed up and never lost. Users can manually initiate a complete synchronization to incorporate all historical data, ensuring maximum accuracy.

User reviews

Watchmarker for YouTube is valued for accurately marking watched videos and greying thumbnails, helping users keep track effectively—something YouTube's default lacks. It has been reliable and well-supported over years, making it an indispensable addon. However, recent Chrome updates, especially Manifest V3, have caused functionality issues, including failure to mark YouTube Shorts as watched, frustrating many users. The extension also lacks some management features like bulk deletion and occasionally misorders watched videos. Despite challenges, users highly appreciate its usefulness and hope for updates to fix current problems.

Pros

Effectively marks watched YouTube videos and greys out thumbnails for easy identification
Highly useful and indispensable for users to track which videos they've watched
Works better than YouTube's basic functionality and Order of watched videos is mostly correct
Has been maintained with responsive developer support over years
Free with continuous improvements and frequent fixes

Cons

Stops working properly after Chrome updates, especially due to Manifest V3 enforcement
No longer properly marks YouTube Shorts as watched, which diminishes its usefulness
Lacks bulk management features like deleting multiple entries at once
Some issues with synchronization causing watched videos to appear out of order
Can interfere with new YouTube layouts requiring temporary disabling

Since the Watchmarker is seemingly no more, how do I extract the information in the .database file, and import it to other "watched" type add-ons? For example, the "YouTube Watched Marker" has an option to import a txt file, but can't import the .database file. This was an indispensable add-on for me. Now looking at other options.

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Watchmarker for Youtube requires a lot of sensitive permissions. Exercise caution before installing.
