Has hidden Google Analytics and is close-source - no thanks. An extension of this privilege level needs to be fully transparent. It also begs for donations at an abnormally high rate.

Use ViolentMonkey instead.

数ヶ月前の更新の際、これまで作ってきたユーザースクリプトのデータが全て消滅しました。
あらゆるデータベースファイル、削除されたデータ等を探しても残っておらず、途方もない損失に嘆きましたが、少しずつ復旧させてきました。

そして今日、Firefoxを再起動した際、再び何かのトラブルで全てのユーザースクリプトが消滅しました。
もうこれ以上信頼を預けることはできません。ViolentMonkey等への移行を速やかに行います。

Apparently it is not only a mess, it's also bloated, closed source now, and has fucking Google Analytics.

Closed source, bloated, uses google analytics, and did I mention it's closed source and uses google analytics. I would suggest users not use this extension, and use FireMonkey or ViolentMonkey instead.

ts updated and deleted all my installed userscripts 😩

Latest release has broken Firefox. When starting Firefox it no longer allows any network connectivity. Unable to even open google.com. Totally and utterly broke in latest update. When it does open it takes over 5 minutes sometimes before I can browse.

Use “Greasemonkey” or “Violentmonkey”, both open‑source, whereas “Tampermonkey” is closed‑source.

Well-designed addon, but I find that it's a shame for it to have gone closed-source 10 years ago. No thanks, I'll switch to ViolentMonkey, which I can read the code of and modify as I please.

Nice add-on, awful privacy policy.

It does not work

not work

The latest update makes every page, regardless of whether I have scripts enabled for them or not, completely unable to load
