A great extension. People, please wait for the addon to be updated, it's mozilla you're waiting on as this is a "Recommended" addon and has to be approved by them. There's already and update that you can grab from the github and it works perfectly. The dev has already published the update, they've done all they can on their end.

Doesn't work anymore

This addon no longer works anymore on Firefox.

1 star until it doesn't work.

Please stop downvoting because it stopped working. You can read. Youtube broke it-
Please wait till the author makes an update (if possible).

stopped working. YT must have changed its approach.

It's been working great until few days ago thanks to yt/goog. Hope the author would update this handy extension soon.

Solid, no-frills extension that returns what should still be a basic feature to YouTube.
Currently doesn't work, but that's because YouTube did yet another update trying to break stuff like this.
Hope this extension gets updated soon, but appreciate all you do either way.

please doit update. not work

This plugin did exactly what it says on the tin, but it no longer seems to, and it doesn't seem to be the author's fault. It needs an update as soon as possible.

Currently doesn't work :(

Never worked for me on Firefox.

Love this plugin. It's been working without any issue until youtube ruined it all with a stupid update :L
