1) HTML5 Videos published with the JWPlayer can't be played (JWPlayer error code 224003),
2) would be nice to have further presets, e.g. enhancing spoken words.

I would give four stars when there is no interference with JWPLAYER.

Не проигрываются видео-тизеры на страницах магазина Стим (и на некоторых других сайтах). Помогает только полное отключение дополнения в настройках браузера (НЕ в настройках дополнения) и перезапуск браузера. 3/5

Video teasers are not played on the Steam store pages (and on some other sites). Only disabling the add-on completely in the browser settings (not in the add-on settings) and restarting the browser helps. 3/5

Not working on NETFLIX videos, please check...

it works well but has "side effects" as written by others on various player. On bandcamp for example prevents playing a song, on youtube doesn't work the change of playback speed. So, if you need it works very well but keep in mind those bugs

It breaks some websites and video players

The plugin works very well at what its supposed to do, but unfortunately it has a major side affect.
It prevents video thumbnails from previewing videos across all sites and even prevents videos from playing on some sites.
So even though its a good equalizer its unusable because of its major side affect.

The only EQ that works for me, and it does a good job.
