It's a great extra but currently the inline style picker isn't working.

good addon, although i feel its a bit too bloated. itd be nice to trim additional resources like extra styles, keymaps, prefer bundling min js/css to help keep size down.

Is there a hope to port this great add-on to Thunderbird 68.0+ ?

Удобно, стабильно, отличный редактор и система обновлений.
Слабое место не в самом дополнении, а в используемой базе от Stylish. Сайт userstyles .org кривой и тупой: ни сортировки, ни нормального поиска по полю, это ад. Встроенный в дополнение поиск по нему этого тоже не дает, а поддержки альтернатив нет - только копипаст стиля вручную.

seems to load styles slower on FF, like in Google Search, Chrome version does not have this issue.

Needs a "dark mode" (like on Windows)

no se deja instalar

There should be a link to popular CSS repositories. I'm not a web developer so I'd rather use high quality content others created.

after 1.5.2, sometimes the addon failed to load the page, need multiple hard refreshes to get it working.

Since Stylish did stupid things, I appreciate that this addon was released earlier

By the way, as for the question, which is the profile directory or the file where the setting contents of this add-on are saved?

And, to say, I want to use the software called Allway Sync to match the contents of Stylus from any PC
