this plugin tracks your internet traffic. This cannot be tolerated

According to this article the Stylish browser extension violates your privacy by sending your browser history to foreign servers

This cannot be tolerated and breaks trust. No more Stylish for me.

Not working in Firefox 61.0

Слепящие ночью страницы Файрфокса и Гугла, так и продолжат ослеплять. Зятемняет то-же что и другие псевдо-затемнители - не то что надо.

Puts items in the context menu without asking or having an option to turn it off.

動作が重たくなるし、設定通り正しく動かない時がある。
最も重要なのが、バックグラウンドで通信している。

It doesn't work: "Возникла ошибка доступа к базе данных Stylish"

database error!

causes high cpu usage for no reason and has questionable data collection
will move on to another plugin

This addon seemed to work on the past months but now! IT DIDN'T !! rather it gives me like a database error though... reinstalled then it's still same rip stylish... well i'm actually done and would never look again

v3 は v2 とは似ても似つかない、偽物という言葉がピッタリくる。v2 からの移行ができないだけでなく、多くの劣化点があり、使い物にならない。

・極端に重くなる（v2 では問題なかった）。
・スタイルが反映されないことが多い。
・エディタは指摘するのが大変なくらいバグだらけで、まったくの役立たず。

"An error has occurred using the Stylish database. Would you like to visit a web page with possible solutions?"
What is going on here?!!? Add on can't be opened anymore :(

Error!

useless with Quantum

I've downloaded Firefox. Cannot find the button to add to Google Chrome. Very frustrating!
