TLDR: Random user id used for counting votes is personal data by law and by mozillas rules. that's why this warning appears.

I understand why the permission labels changed how you felt about the extension.

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

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

RYD only uses the data needed to display 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 permissions 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 is about YouTube activity. The extension isn’t watching everything you do across the internet - it simply can’t do that with these site permissions.

The new labels can sound worrying, but they don’t give the extension access to any more websites.

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