Preview Tabs With This Mozilla Extension
This is just a quick plug for a Firefox extension I don't hear anybody talk about. Everybody extolls the virtues of Session Saver, Greasemonkey, and some others but I also like Ted's Tab Preview. When you have multiple tabs open in Firefox, it shows you what is on each tab in a miniature preview as soon as your mouse moves over the tab. So, if you have multiple tabs that have the same title, no title, or you've just forgotten what you are doing, you don't have to click on each one and wait for it to draw.
