Not great, when I try open the extension it says, ' Firefox doesn't allow you to open this extension ' and other things.

This goes straight to the box of essential extensions! Very well done, with all the necessary options for creating and managing CSS to overwrite and override those pesky Pages that use grey characters over white background or that decide that we would all live better with blinking buttons or whatever.

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

AWESOME

Thank you for this amazing add-on! I used Stylish years ago, but now it's a malware! I'm so happy that this fork Stylus exists as the good old community driven the other one used to be.

PRO TIP: Use the Developer Tools (Inspect Element) to change your styles interactively, then go to the Changes tab, click on Copy All Changes, then paste that into the Stylus editor!

Thank you!

very nice and fast
