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。

In the past, great, but now unworkable. When i'm set the derective @grand none, i still can not see objects in the DOM, i can only access them through unsafeWindows. This crashed all my scripts

Nach dem Update vom heute funktioniert es gar nicht mehr. Wird gar nicht mehr getestet, bevor man ein Addon aktualisiert?

Wait. How do I *write a new script* with this extension? What a thoughtless omission (besides so many others)! Once the most powerful extension of the web, the author's "I don't care if it breaks everything before" attitude has really done very very bad to it. Not usable anymore, going to TamperMonkey. It was good while it lasted, GreaseMonkey, may be we'll meet again some day.

火狐57之後都無法正常運作

it's already activity but doesn't work on firefox 57

Hope the dev port this to the forks of "gecko" browser instead.

I add to the chorus of users who say Greasemonkey doesn't work anymore in Firefox 57.

Ne fonctionne pas avec Firefox 57.0
Probablement un problème avec la fonction xml.httprequest

It was great until Firefox 57 and version 5. Now I can't install any new scripts whatsoever and every single one of mine is broken. I've spent the past several hours trying to get them work and they don't anymore. I've moved to TamperMonkey now which works like a charm.

Greasemonkey 4 is a piece of crap that I would HIGHLY recommend avoiding.

Greasemokey was great... until they seem to have decided that "Less is More" when it comes to their program. The new updates roll in and suddenly I can't do half of what I used to, and half of my scripts are gone and can't return. I can't even manually write scripts into it anymore, they have to be put on their download site and pulled from there. Yeah, no thanks, Mozilla is already spying on us enough already, I don't care to invite more.

It was a good run, but it's over. Sorry to see you fall, Greasemonkey.

Installation following the information provided was not successful.

Everything was good until the authors decided to go with backwards incompatible changes for v4. There are lots of user scripts which are not going to be updated in a timely manner (or even ever). Personally I can not support a decision to be progressive at the expense of the end users. And considering the presence of mature and steady alternatives to Greasemonkey I don't see any reason to stay here.

Все было в порядке до тех пор, пока разработчики не приняли решение сделать версию 4 обратно несовместивой. Существует множество пользовательских скриптов, которые не будут обновлены своевременно (или вообще когда либо). Лично я не поддерживаю решение быть прогрессивными за счет пользователей, и, с учетом существования надежных альтернатив, не вижу причин оставаться на Greasemonkey.
