Stumbled across this neat little entry (courtesy of a blog entry on javablogs.com), which allows you to modify the userChrome.css file to have your unread tabs italicised (and/or colour). Simple and effective. The details can be found here. The easiest way is to grab a copy of the ChromEdit extension and edit the userChrome.css file. Scroll to the end of the file and paste in the following code to italicise unread tabs: [code] /* Italicise the title of unread tabs */ #content tab { font-style: italic !important; } /* Normalise the title of selected tab */ #content tab[selected=”true”] { font-style: normal !important; } /* Normalise the title of read unselected tabs */ #content tab[selected=”false”] { font-style: normal !important; }[/code] Note you’ll need to re-start FireFox once to load the ChromEdit extension and another time to have the style sheet take effect. And over at DevNulled there is a good post on how to speed up FireFox. Be warned though: it really does increase the load of the server you are trying to connect to, which strictly speaking isn’t very polite.
