How to ditch a fantastic add-on... 3.0.1 screwed up (again) my styles!

Did you guys took into consideration that there are people still using Firefox 52.4.0 ESR?

PLEASE DO SOMETHING!

vi segnalo che l'estensione è buggata

sia nella versione per chrome che per firefox

l'aggiornamento degli stili non funziona correttamente

primo quando vai nella ricerca degli aggiornamenti e fai "installa aggiornamento"

e clicchi su "update style" nella pagina dello stile

su firefox non succede nulla e non si apre nessun popup

e quando rifai la ricerca degli stessi risulta non installato

quando invece lo è

e ti richiede l'aggiornamento

dopo questo update

mentre su chrome su alcuni stili lo da ogni volta anche se successivamente dice "style installed"

spero che fixate questi bug

3.0.1 Addon is broken, Styles disappeared after update today.
button does not work, will lead to nonexisting help site or similar, failes...
something with database wrong.
perfect how to destroy a working addon.
switched back to old 2.1.1
does anybody test this before release?

Stylus exists, that's what Stylish 3.0 supposed to be

Since WE version It doesn't always implement styles properly when loading multiple tabs simultaneously. I have to reload them one by one manually every time - please, fix it! BTW, Stylus works fine - just a fact.

The new version is buggy as hell. In Firefox for Android, I can't access my installed styles anymore from the Add-On tab and the new Stylish menu entry doesn't do anything at all. Every now and then Stylish seems to forget the installed styles (which were all gone after the update and had to be reinstalled in the first place). Even if it does remember the styles, they're only getting applied after the page has been drawn. Not good. What, exactly, is the 'up' in this so called update? For the time being I've reverted back to 2.1.1.

Зачем сломали расширение которое работало идеально?!!!
Как вернуть старую версию расширения?!!

Update was a disaster, should have known not to fix what wasn't broken. Pls give instructions for restoring old version from a backup profile. EDIT: Found the link for restoring my previous version (just above release notes towards the bottom left, in case anyone else needs to do the same) - thanks for keeping it available.

1.- The first webextension is not working properly for me. Firefox freezes from time to time and I need to kill firefox.exe process.

2.- I can´t open preferences window, because clicking on "create a new style" or "manager styles" options, does not doing nothing, I need to click on "edit" option on some installed addons to open addon preferences.

3.- I installed some style like https://userstyles.org/styles/25811/amo-dark-theme but sylish is not aplying the style. The style is properly applied by using latest Legacy version.

I imported manually an own style, and the style has been applied properly.

4.- There is no option to apply style as preview or I can´t find it, it is very useful to test style code modifications before saving code changes.

4.- I personally, I don´t like anymore the new Stylish style, splitted by sections.

I like the old stylish style , where you can see the whole style code while editing, making some modifications and preview changes before saving changes.

Please, can you add some option to use the old Stylish style, to create/see/edit/paste the style code as the legacy style versions?
