Firefox Add-ons

These are some Firefox add-ons that I find useful.


Xmarks, formerly Foxmarks, is a browser add-on that synchronizes bookmarks across browsers and computers.  In addition, Xmarks stores the same bookmarks online for web access from any computer.  To use Xmarks when it has been installed as a browser add-on, provide ID and password via the dialog box that will pop up upon browser start up if you are not already logged in.  To use Xmarks web access using any browser on any computers, navigate to, click on My Account, then provide ID and password in the fields provided.

As of September 2010, Xmarks works with Firefox, Safari, Chrome and IE.  There's an Xmarks app available now for iPhone/iPod Touch/iPad, and one coming soon for Android.  Even without an app, you can point any smartphone to and get mobile access to bookmarks.

As of version 3.8, when used with Firefox, Xmarks supports synchronization of bookmarks, passwords, open tabs and browser history.  Not all features are available for other browsers.   Currently, I only make use of synchronization for bookmarks, which works in all versions of Xmarks.


ColorZilla is a Firefox add-on that provides tools for web page color analysis.  (As of September 2010, ColorZilla does not work with any other browsers.)  Once installed, ColorZilla provides an eyedropper and a pull-down menu in the lower left corner of the browser frame.  The eyedropper can be used to find and copy (in various formats) the values for any color on a web page.  In addition, the pull-down menu can be used to access a color picker, palette tool, and webpage DOM color analyzer.


Flashblock is a Firefox add-on that prevents automatic execution of Flash objects.


BetterPrivacy is a Firefox add-on that removes files created by Flash to store certain kinds of user data.
