Awesome Firefox Add-Ins

I use Firefox and recommend it - it is a killer browser and the add-in functionality is what makes it so great. There are a lot of developers out there doing some great work which allow me to customize the browser in more ways than I would consider and the "reviews" and "download" numbers show users like me what peers think of those add-ins. It is a very smart way for the people at Firefox to enable users to choose the "best" features for the browser.

These are my current favorites:

1. ScribeFire makes it very easy to publish to my blog (I'm using it now)
2. Colorzilla makes it super simple to grab screen colors. I'm doing lots of html emails with simple fonts and colors.
3. MeasureIt makes it simple for me to measure screen elements.
   
4. Firebug lets me inspect the css and html attributes of a page very quickly.
5. Foxmarks is a bookmarking tool that synchronizes my bookmarks across multiple computers.

My one wish list - I want an add-in that helps me organize pages viewed. I never delete my history and am browsing pages that I can't seem to find again days later. I haven't seen this add-in yet. Have you?
