1. Tab Progress Bar:
Best Greasemonkey and Stylish scripts (both are Firefox extensions).
After a slow start, add-ons for OpenOffice.org are finally starting to reach a critical mass. When I last wrote about add-ons for OpenOffice.org in September 2004, the examples were relatively limited, with extendedPDF the outstanding example. Today, extendedPDF remains a must-have -- so much so that Debian versions of OpenOffice.org include it as part of the basic packages -- but the choices have expanded dramatically. There is even a web page that is slowly beginning to rival the Firefox extension page.
1. Nighty Tester Tools - It fixes extension compatibility (makes them all work with the latest firefox version), and adds a few extras useful to those that regularly test nightly builds of Firefox, Thunderbird, Sunbird and Toolkit Seamonkey (umong other things).
2. Better GReader - This extension is for Google Reader, and it Compiles some of the best Greasemonkey user scripts and Stylish skins for Google Reader into one convenient interface.
