A great extension, period.

However, with today's upgrade (v.2.0.117.1) the possibility of hiding comments & chat + hiding related videos (both a HUGE source of distraction, at least for me) does no longer seem to work.

Is it an "infantile dentition" problem of this new version (developed, as I've read in the "News" message appeared after it has upgraded, along new coding guidelines by the Mozilla Foundation), or is Google actively sabotaging that functionality because it is considered a hindrance to their main business (i.e. that of ADVERTISING)?

Let's hope for the first one to be true...

P.S.: I add that in Chromium the same v.2.0.117.1 of the extension seems to work as usual 🤔

P.S.2: today (October 22, 2022) the extension (v.2.0.117.3) has started to work again even in Firefox. Great job 👏👏👏👏👏👍👍👍

Spectacular add-on. YouTube is infinitely better with it. Excellent work from the developer and hope this keeps being maintained forever. I install it in all browsers that I use.

Очень полезное расширение.
С помощью него я ускоряю/замедляю видео; отключаю автовоспроизведение, меняю темы оформления. Есть полезные функции вроде громкости по умолчанию и автоматического выбора нужного кач-ва воспроизведения.

Отличная работа

Five stars for one of my top five add-ons I can't live without.

excelente extension, funciona bien

I just want to express my feelings of gratitude for this extension! :)
