Thanks for sharing your concerns.

The extension is actually recommended by Mozilla, so they do not consider it harmful or dangerous.

RYD hasn’t changed how it handles your data. What changed is Mozilla’s wording for these permissions - not what the extension does with your data.

The extension uses only the data needed to show dislikes and count votes.

Its site permissions cover YouTube and its own API at returnyoutubedislikeapi.com. RYD doesn’t read other websites, and these site permissions cannot be used to access them.

Here’s what those permission labels mean:

Personally identifiable information - RYD’s randomly generated, anonymous user ID, used to count votes. This isn’t your Google or YouTube account.

Browsing activity - opening the next YouTube video, so the extension can send its video ID and fetch the new dislike count.

Website content - things like the visible like count, which helps calculate dislike estimates.

Website activity - clicking Like or Dislike.

Again, this refers to activity on YouTube. The extension isn’t watching everything you do across the internet - it simply can’t do that with these site permissions.

The new labels may sound scary, but they don’t let the extension access more websites.

RYD is open source, so you can see how it works: https://github.com/Anarios/return-youtube-dislike
