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.

active but not working in firefox quantum

This is madnes!

Besides questionable decision to go with incompatible changes, was it really necessary to make WebExtension version FF 57+ only??
With current FF mess the only reasonable option is to keep FF 56 while slowly upgrading extensions or searching for replacements.

Since Firefox Quantum is released, your extension no longer automatically updates scripts.

Im playing grepolis. since upgrade, i cannot zoom in/out in the game end the wall isnt counting for losses

The new version is bad, some scripts are not working, others are so slow to be executed.. i wish you can just port the old version to Firefox Quantum.. i switched back to Firefox 56 just for the old version of Greasmonkey.

Userscript addon that forgot the ability to add custom userscripts? Added breaking changes to API but in order to modify my userscript to make it work again, I had to download someone else's userscript from a website then edit it and paste my script over it because there is no "Add script" button anymore. I'll fix the changes but be asking all of my users to switch to TM.

This addon is not working correctly with Firefox Quantum. There is no way to edit and save and I can not see how to add my own scripts. :(

Greasemonkey is not compatible to itself since ported to webextension (FF57).

Your argument "We have to do it this way becasue of webextension" is useless, tampermonkey and USI had it done without breaking th API!

Sorry guys but you I went over to tampermonkey and USI to keep my scripts running!

Doesn't install a single script as of the update. How to install manually is nowhere to be found. This script is useless. Using latest Greasemonkey with Firefox Quantum.

Раньше он работал идеально, но новая версия для WebExtensions просто не работает, её не нужно было выпускать, лучше бы доработали, ждем обновлений, а пока буду сидеть на Violentmonkey

Well this is just STUPID. This new version broke pretty much all my scripts. Is there even a point to this addon anymore? Why use this and have a bunch of broken scripts when I can just download Tampermonkey which also works with FF57 AND doesn't break all my old scripts? Give me one good reason.

Spent half an hour trying to find how to install a script I've been using for years and it is now no longer working.

Developer is a lier! Yes it launches in FF 57, but there not a single script working!

pas moyen de l'installer a cause d'une perte de connexion ou un truc comme ça ...
