This mod need to be updated to the new design of Youtube website. Without the addon "YouTube Classic" this one isn't working, but it's ugly to use this mod ...

Doesn't work at all on Mozilla Firefox

Doesn't work at all with Firefox, even WITH the YouTube Classic addon. UPDATE IT ALREADY!

does nothing

used to work. Now doesn't. probably because of google changing code in Youtube or something. But as it stands it doens't work anymore. needs to be updated

Have used it for a long time. Used to work perfectly, but now it's broken with no word of an update...

not working

Works well in Chrome, but is broken here in Firefox. Sad.

not working now...

I managed to skip the update last year that was actually a rollback to a previous build that broke the extension, but now the working version that I had for the past couple of years no longer works. It would be great if you updated this...

Broken. Doesn't work anymore. Last update was 3 years ago. It's dead Jim.

Simplesmente parou de funcionar

Do not Install this Crapware....it should be removed from FIREFOX!

does nothing

You click 'Block videos from this channel' option, but it does nothing.

For Mozilla users;

Works great. All you need to do is just clicking the "X" that appears on the video thumbnail.

Does absolutely nothing in Firefox.
