- Rated 1 out of 5by Firefox user 12964980, 8 days agoThe add-on no longer works in private windows, so it is completely useless to me.
Developer response
posted 8 days agoYeah, it will be addressed later. Mozilla forbids data collection in private windows - which means you can't submit likes\dislikes in a private window. It isn't a problem, but requires additional coding, which I didn't have time for. - Rated 1 out of 5by Firefox user 18924088, 8 days agoRemoved this extension when out of nowhere it tried forcing me to agree to invasive data collection. There is no need for this.

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.
Ajay, the author of SponsorBlock and DeArrow, has also raised this issue with Mozilla. He explains how the new wording can make an existing extension look like it suddenly started collecting new data, without making clear which websites it can access. You can read his post on Mozilla’s forum here: https://discourse.mozilla.org/t/the-new-data-transmission-permissions-seem-to-be-misleading-to-users/149410
The extension only uses the data it needs 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.
Let me explain 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 sound scary, but they don’t give the extension access to more websites.

Handling YouTube-scale traffic and storing dozens of terabytes of like/dislike data on a school-lunch budget ain’t that easy. The funding from these features is what keeps RYD’s servers running.

I was scared and skeptical at first, when I noticed what it was asking for seemed like invasive permissions. After taking literally seconds to research why/what had changed, I found out what was going on — nothing more than Mozilla just changing the wording of their policies.
This add-on is still safe to use and does not collect any sensitive/personal information about you or your browsing.
P.S. If you think this review was written with AI because of the em-dash, there's no hope for you :-)Developer response

Like many others I was curious what the new permissions popup means, so I came to check. Easy 5 stars not just because it's a fantastic extension, but also because of the fantastic transparency and clarifications of the dev. Definitely would recommend this one!
