Thanks for explaining your concerns about the permissions.

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 how Mozilla labels these permissions - not what the extension does with your data.

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 such as the visible like count, used to help 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.

Those new labels can sound scary, but they don’t let the extension access any more websites.

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