A request: if you intend to link to this entry, please link to http://blog.codefront.net/mozilla/unreadtabs/ instead.
As requested (by 2 people) in my previous entry, here's the Unread Tabs extension for Firefox:
Also available from the Firefox Add-ons site.
This extension italicizes the title of tabs that you have not yet read so that you can keep track of what youï¿½ve read and what you havenï¿½t.
I claim no credit for the extension: CSS comes from the Change the style of tab markers entry in the MozillaZine Knowledge Base. Thanks to an anonymous commentor, the CSS is just a single rule (rather than the 3 in the Knowledge Base entry linked to above):
font-style: italic !important;
This has to be the world's simplest extension with some boilerplate XUL, an empty stub JS file, and a single CSS rule. I simply stripped almost everything out of another extension that I was working on (I've hit a snag on that one though) and did some run-of-the-mill search and replace.
