Rated 4 out of 5 stars

Tip: Stylish can edit your Chrome settings, too! With no @-moz... pieces, try something like this: menu[label="Help"] { display:none; } The advantage here is that you can edit your Chrome without restarting FF.

Gripe 1: Greasemonkey allows 3rd-party editors, but Stylish is stuck using a basic XUL text entry box. ... This is mostly solved by the "It's All Text!" add-on.

Gripe 2: Great integration with the userstyles.org site, but the site isn't as featureful as userscripts.org, and while you can submit and import, there is no auto-update mechanism. How do I know when something is updated? I'd propose: upon loading an imported style, if Stylish hasn't checked for updates on that style in the past week, check for updates and prompt the user if there is one. An option should be available to stop the prompts (and not install), auto-install instead of prompt, or never check. Another option should allow checking all of them when prompted, or on a schedule. One must also be able to disable updates on a per-style basis.

These gripes are minor. Stylish is a great boon to the web.

This review is for a previous version of the add-on (0.5.7).
