What is the update error (can't access lexical declaration "metaParset" before initialization)?

It used to work great but the functionality to search for existing themes for the site you're on takes a very long time to search, and for some sites just doesn't ever return any results.

Simple and "easy" to use.
The 3rd party website containing the userstyles is awfully slow. (This didn't influence my rating)

Great addon, but has it's limits. Also userstyles.org page works very poor, so getting styles is very hard.

I've been using this extension since the privacy problems caused by Stylish and I find it very good. I appreciate the editing capability and I started learning CSS by tinkering with the code.
The connection problems encountered on userstyles.org make me lower my score but Stylus is not responsible for this defect so 4 stars for them. Thank you for your work.

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.
