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

user styus website does not work

Slowpoke... Takes about 5 minutes for it to understand that the ONLY style actually DOES exist. Until that it strongly believes that there is absolutely NO styles.

been using this a long time and it is such an excellent extension that, given its syntax highlighting, checking and auto-complete, can help one learn css in addition to applying it

and here i'm adding a 6th star just because of it perfect privacy policy...

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

It does the job.

I appreciate this addon however, where and how do people get styles now? The userstyles.org page has been completely effed up for a long time now, it's unbelieveably slow or it just doesn't load. I didn't know it was possible for a website to run that badly in 2020.
If anyone could reply, it would be greatly appreciated. I am not the best with computers but I at least figured out this addon.

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.
