NO ME DEJA PONER NINGUN TEMA

No funciona

The owner of userstyles.org incorrectly configured his website. To protect your information from theft, Firefox did not connect to this website.

This site uses HTTP Strict Transport Security (HSTS) to indicate that Firefox should connect to it only through a secure connection. As a result, you can not add an exception for this certificate.

The new CSSLint feature is beyond annoying and looks stupid. It shows warning like "Don't use IDs in selectors." and "Use of !important". How is it possible to change the style without using "!important"?

There should be a way to disable it or fine tune those warnings. Or better, just completely remove it and save some CPU resources and developers' brain cells.
