For all of those leaving bad reviews about Greasemonkey 4, it only works properly with FF57+. If you are using FF56 or lower, use version 3.17 and do not update. If you got automatically updated and things got broken, you can reinstall the old version by following this link: https://addons.mozilla.org/firefox/downloads/file/736199/greasemonkey-3.17-fx.xpi?src=version-history . Once back on 3.17, make sure you go immediately into the add-ons manager and turn off automatic updates for this extension. Anthony, you may want to put this info up front on AMO.

fk 4.1

New version is completely broken. Use Tampermonkey instead.

hh

Scripts are no longer listed under addons in 4.1
I do not know how to keep scripts updated now

The new version is absolute garbage. It updated on me just now and I lost all of my scripts. The exact same thing happened to Stylish!

So, I turned off automatic updates for Greasemonkey and installed version 3.17 and now everything is fine. I did a very similar thing for Stylish and that worked as well.

I will be avoiding all new versions of Greasemonkey.

All I think is its just amazing app..

4.x is as useless as Firefox 57.

thanks for the new awesome force-uninstall-gm feature. its great!!

I appreciated GM for a long time. Thank you for all the free work. I've to leave because GM does not fit to my needs anymore.

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

自从Firefox更新到57.0.2以后，脚本都不能用了。
