User Reviews

Users broadly praise YTBlock for effectively blocking unwanted YouTube content—videos, comments, channels, and playlists—and for flexible blocking options (keywords, category restrictions, and per-item blocking) that tailor what appears. The extension is seen as a major improvement to the YouTube experience, reducing toxicity and clickbait. However, recurring issues include reliability after updates, browser slowdown, and inconsistent blocking on the homepage versus video pages. Some users note that blocking may depend on an overlay, and homepage coverage remains incomplete. Overall, it works well when it functions but maintenance and reliability concerns persist.
Pros
  • Effective filtering of unwanted YouTube content (videos, comments, channels, and playlists).
  • Flexible blocking options including keyword-based blocking, category restrictions, and per-item blocking.
  • Improves the YouTube experience by reducing toxicity and clickbait.
  • Works on search results and in private windows (coverage beyond the homepage).
Cons
  • Reliability issues after updates; some users report it no longer works.
  • Notable browser slowdown and CPU usage impacting performance.
  • Blocking is inconsistent on the YouTube homepage/main page versus video pages.
  • Blocking sometimes depends on an overlay and may not occur if the overlay is disabled.

It was hard to figure out how to do what I wanted, but it works. Though it's the only extension of mine that causes firefox to show "this extension is slowing down the page" message
