Extensions
Last Updated: September 9, 2025

I have discussed many extensions (add-ons) in my Blog over the past year. However trying to find a specific extension is not easy. You can try to do a search on the Blog, but if you are not sure of the name that won't help. You could even look in the Add-ons tag, but that brings up everything that has to do with Firefox add-ons. So I decided to create this page to act as an index/cross-reference to the main extension articles in my blog. Have an extension (Firefox, Thunderbird or Flock only) you would like The Guru to review? Send your tip (Extension name and URL) to: [email protected]

Name - The official name of the add-on
Description: A brief synopsis of what the add-on does
Works With: Firefox Flock* Netscape 9** Thunderbird Not Available
Main Article: First main (in-depth) write-up I did on the extension
Other Article: Review or partial (overview) write-up
Site: Direct link to the add-on site. This is may be a link to the AOM (addons.mozilla) or developer's site
Comments: .Notes, advisories, etc.

* Extensions reviewed after October 8th, 2007 are no longer tested for compatibility with Flock.
** Extensions reviewed after March 1st, 2008 are no longer tested for compatibility with Netscape.
