Version 4.1 is incompatible with Firefox 52.5 ESR.

I've downgraded back to the one which is compatible.

great addon !

4.x version broke the scripts.

Time to uninstall and change to working addon.

With the installation of 4.1, all my user scripts are gone, and there is no way to add a new one from the backups I had because the new user script button doesn't work 90% of the time (you have to click and wait up to 30 seconds to get it to pop up, and most of the time, it never does) and when it does, I can't save anything. This is on 57.

Where is the quality checking before breaking our web experience? Moving on to another scripting engine. Good grief.

all my scripts disappeared after updating to version 4.++

if this happened to you a fix is to reinstall the old version again

you will find your scripts back :)

for developer you need to test you addon before releasing a major update

嗯，上周反馈 API 的兼容性问题，非常高效率的修复了。
知错能改善莫大焉。

One of the best addons I have ever used. Tired of too many intrusive "disable adblock" boxes such as on the sims resource? There's a script for that. Tired of youtube constantly replacing youtube with the new layout no matter how many flipping times you tell it to keep restoring the old youtube? There's a script for that. Those are the only two I use, but many others have used it far more extensively with positive results.

Do not use THIS. Use Tampermonkey - it's much better!!

Не используйте ЭТО. Используйте Tampermonkey - он гораздо лучше!!

i'm very statisfied using this addon

好用，自己修改的脚本不知道怎么保存啊

I was forced to upgrade to GreaseMonkey 4.x with Firefox 56.0. My scripts stopped working. I wrote them, so I looked into fixing. I looked at the GreaseMonkey web site. I saw the general notice about the changes but could not find specifics. Didn't trust what I saw when I saw notes like "this script" hasn't been updated in years.

Fix up documentation. Provided example scripts with before and after changes.

Give warning if it doesn't work in Firefox 56. I tried Firefox 57, but that caused other problems for me.

Was able to turn off auto updated of GreasMonkey before downloading 3.17 version of GreaseMonkey. add ons > GreaseMonkey entry > more > click on off selector. See below for the link by Anonymous user e7bdbb to the download.

PS. There is snow on the ground as I write this :-(
PSS. FYI. Tampermonkey gave me a compile error on "for (var elmForm, i=0; elmForm=document.forms[i]; ++i)".

В один прекрасный день все сломалось. Непонятно, какие скрипты активны на какой странице, нет кнопки manage scripts, ни один скрипт не работает. Верните все, как было!!!
It was a dark and snowy night. The day couldn't get any worse, right? Where is my Manage scripts... button? Nothing works anymore! I can't get no heads, nor tails about which of my scripts are supposed to run on any particular site. All of them are displayed as active. The scripts that used to work just fine, they all stopped working. All of these damn ads are popping up EVERYWHERE! I'm close to a nervous breakdown, can't visit any of my favourite sites anymore without my eyes bleeding out. Damn it all and merry Christmas to ye all.

很优秀的插件，感谢作者！
