- Rated 2 out of 5by Judas, 30 minutes agomy browser has been taking a whole lot more memory since this got updated...
- Rated 1 out of 5by Firefox user 13927441, 43 minutes agoThe developer claims that Mozilla changed the labeling system, but I have a lot of extensions installed, and none of them asked for additional permissions to collect my data. Why do I smell bs?
If you are a scammer, say: "Thanks for taking the time to leave a review.
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."Developer response
posted 20 minutes agoOther extenions haven't requested it because they haven't gone throught the "data disclosure" process yet (check Sponsorblock's response in my discord server). This extension is just among the first few unlucky ones. - Rated 1 out of 5by Firefox user 20155068, an hour agoNew permission requirements make this an automatic hard pass - recommendation should be revoked.
Edit in response to the developer:
I think you're missing the point.
The issue isn't that Mozilla suddenly gave RYD access to the whole internet. It's that Mozilla has now made explicit data collection that was apparently already happening, but wasn't previously disclosed.
And "anonymous user ID" doesn't really solve that. It's a persistent identifier tied to YouTube activity. That's pseudonymous, not meaningfully anonymous.
More importantly, the extension being open source only tells us what gets sent. The RYD backend is still a black box. Once that data leaves the browser, we're being asked to trust RYD not to retain, correlate, profile, monetize, or sell it — particularly after we've learned the collection was previously undeclared.
The fact that the data is useful to RYD doesn't mean it's necessary for the extension's basic advertised function. Showing a dislike count doesn't inherently require building a persistent record of users' YouTube activity.
And the Chrome and Firefox stores don't even have identical data-collection declarations, so "Mozilla just changed the labels" doesn't really explain everything away.
That's why I find the response a bit tone deaf. The concern isn't "OMG, RYD can now read every website." It's "why does a simple dislike-count extension need to collect this much information about my YouTube activity, and why was that collection not clearly disclosed before?"Developer response
posted an hour ago"why simple dislike-count extension need to collect this much information about my YouTube activity" - it's explained under every review here. Try reading the response, please. I literally list every point, and why it is there. They are trivial, like detecting what video is playing (to show dislikes for that video) and detecting that like or dislike button was clicked.
I'll copy-paste it once more
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. - Rated 5 out of 5by User, an hour agoThank you so much for making this extension that helps us to not get scammed on YouTube, among other things.

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 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.

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.

Developer response
posted 2 hours agoDanke für dein Feedback. Es tut mir leid, dass du wegen der Erweiterung ein ungutes Gefühl hast.
RYD hat den Umgang mit deinen Daten nicht geändert. Geändert hat sich, wie Mozilla diese Berechtigungen bezeichnet - nicht, was die Erweiterung mit deinen Daten macht.
Die Erweiterung nutzt nur die Daten, die sie braucht, um Dislikes anzuzeigen und Stimmen zu zählen.
Ihre Website-Berechtigungen gelten für YouTube und ihre eigene API unter returnyoutubedislikeapi.com. RYD liest keine anderen Websites aus, und diese Website-Berechtigungen können nicht genutzt werden, um auf sie zuzugreifen.
Personenbezogene Daten - die von RYD zufällig generierte, anonyme Benutzer-ID, mit der Stimmen gezählt werden. Das ist nicht dein Google- oder YouTube-Konto.
Surfaktivität - das Öffnen des nächsten YouTube-Videos, damit die Erweiterung dessen Video-ID senden und die neue Dislike-Anzahl abrufen kann.
Website-Inhalte - zum Beispiel die sichtbare Like-Anzahl, die bei der Berechnung der geschätzten Dislike-Zahlen hilft.
Website-Aktivität - das Klicken auf Like oder Dislike.
Noch einmal: Hier geht es um Aktivitäten auf YouTube. Die Erweiterung verfolgt nicht alles, was du im Internet machst - mit diesen Website-Berechtigungen kann sie das schlicht nicht.
Die neuen Bezeichnungen klingen beunruhigend, geben der Erweiterung aber keinen Zugriff auf weitere Websites.

It's still sad that we even need an extension like this, but it's not doing what the 1-star reviews will have you think it does.Developer response

Developer response
posted 5 hours 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, 5 hours agoRemoved this extension when out of nowhere it tried forcing me to agree to invasive data collection.

posted 5 hours agoSorry the message about new features bothered you. It’s shown only once during the lifetime of the extension, and it’s timed to appear after a browser restart - hopefully the least disruptive moment.
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.
