After an extensive alpha and beta process, Firefox 1.5 is getting closer to release. The first release candidate or RC1 is now available from the Firefox Project site. So now is probably a good time to throw out some compatible add-ons that work with 1.5.
ColorZilla is my favorite color wheel tool for web development and something which I have learned to depend on more than any other online color reference tool.
Google Pagerank Status is a must for webmasters who want to know their pagerank, but who do not want to use the Google Toolbar.

And lastly, my favorite theme is now 1.5 compatible too. Check out SaferFox Xpanded for an interesting Firefox makeover look.
