Review summary

Users find the add-on useful for viewing Reddit comments on videos and generally report it works well. Multiple reviewers warn it triggers Reddit rate-limiting (error 429), which can block Reddit browsing; disabling the add-on fixes this. Users also want it to be passive/by-request and have raised maintenance/update concerns.
Pros
  • Adds Reddit comments directly to YouTube and other webpages, making it easy to see discussions alongside content
  • Reported to work well and function reliably by multiple users
  • Helps surface Reddit discussions that some users find saner or more thoughtful than native YouTube comments
Cons
  • Triggers Reddit rate-limiting / error 429 (too many requests), blocking Reddit access when multiple tabs are opened — reported by several users
  • Runs/acts by default and can be intrusive; users say disabling the add-on stops the problem (suggesting it shouldn’t be always-active)
  • Maintenance concerns noted (users reported long periods without updates)

2025-10-07 Sk***** As of recent, it prevents YouTube comments from displaying, and it does not display reddit threads either, needs to be fixed ASAP!

2025-09-26 Fi***** Since now, the addon is not working and will disable both youtube comments and reddit comments - they are not visible anymore.

2025-08-30 Fi***** I've been occasionally noticing that youtube comments don't appear at all on some videos and narrowed the issue down to this extension. Came here to check if others had the same issue and realize that this extension is what's causing the constant 404 errors on reddit as well! I haven't even opened reddit in hours and I'll still be rate limited leading to constant frustration and having to delete cookies. Plugin still kinda works though! Can't recommend.

2025-08-15 Ve***** Installed this because the previous extension I was using got taken down, and within an hour I was blocked from opening any Reddit links due to error 429: too many requests. I've switched between many extensions which add Reddit comments on YouTube over the years, and haven't had this problem with any of the others.

2025-05-01 Fi***** This addon should be passive by default and only work when user wants. As is, it's triggering Reddit's rate limiting and making it impossible to browse when you open a few youtube videos.

2024-07-05 de***** This add-on has been working without issue since installation. However, in the last few weeks there is now an issue. The issue seems to be that this add-on seems to be triggering some sort of rate limiting from Reddit's servers. It has nothing to do with YouTube. When on Reddit, if I open several tabs the website will refuse to load unless I come back after a 5-10 minute break, activate a VPN, change DNS servers, etc. Disabling this add-on has completely fixed the issue of Reddit not loading. Hopefully this will be fixed in an update. I believe that if this add-on was updated (as of this writing it has been about 8.5 months without an update).
