Great add-on, but having issues after FF13 update Rated 5 out of 5 stars

Love this add-on, use it on my laptop and desktop, very easy to use. However this evening my FF rolled up to 13.0, and now when I try to edit a Stylish style, I can't see the code. This is happening on both my boxes, and also on a Win8 preview release VM I built to test Win8, which also has FF 13.0. BTW, I did try uninstalling and reinstalling on my desktop just in case, but no joy. Hope there's a patch for Stylish on FF13 soon, love the ability to customize any webpage.

Update: I loaded the Stylish-Custom helper ( https://addons.mozilla.org/en-US/firefox/addon/stylish-custom/ ) and now I can edit my styles again.

This review is for a previous version of the add-on (1.2.6.1-signed).
