It somehow got force installed, I was holding off until it was working properly, and now every script is practically busted for reasons that are impossible to figure out because of lacking proper error reporting of cause. At this moment, it has become utterly useless. I have faith in the developer but this has been a truly bad update and now trying to figure out how to revert without losing everything.

GreaseMonkey 4.1 doesn't work (and / or has a compatibility trouble with Ghostery V 5.4.10 - latest fine version) specially under Waterfox latest edition (Seven Pro 64 bits french). Seems to don't have the trouble under FF latest ESR and Cyberfox latest ESR version

The webextensions rewrite is absolutely terrible. Important features, such as automatic scripts update, are missing. Many scripts are broken, such as "facebook unsponsored". Downgraded to older version for now.

This update (4.1) broke all of my scripts. I don't know what you did, but don't do that. Hopefully I can install the previous version to get it working again. I do NOT like the change in the UI, and I REALLY do NOT like that you've made all of my scripts not work. Don't fix what isn't broken.

completely useless

新版火狐浏览器无法使用，功能缺失，连装了什么脚本也看不到

Deleted

自从Firefox更新到57.0.2以后，脚本都不能用了。

In het verleden werkte het goed, nu krijg ik zelfs geen user.js pagina script toegevoegd. Hij zou het uit zichzelf moeten melden met de vraag: install, maar dat werkt dus van geen kant meer.

Het was heel luek, een 5*, nu is het waardeloos geworden voor mijn GC little helper

何もできん。スクリプト生成できん。何も始められん。オワットル。
