Jorge Castro announced the release of a Chrome extension called Chromify-OSD that makes the build-in Chrome notifications use NotifyOSD. I'll make this post short because for some reason the extension doesn't work for me in either Google Chrome or Chromium.

Nautilus Easy Union is a Nautilus extension (comes as a stand-alone application too, but it requires Nautilus anyway) that allows you to create a "union point" which is basically a folder that displays the contents of other (multiple) directories. You can use it for easily accessing all your pictures, music, videos or other files from a single location.

he Chromium developers have been working on extensions sync for some time, but this feature only became functional today. However, it is not available by default for now so you must manually enable it.

You could create every document, spreadsheet, and presentation you work on from scratch, but if you're like me, you'll likely spend more time futzing with the file's layout and design than entering the data that comprises it. That's why I rely on the many free templates and extensions for my favorite productivity apps. I've written in the past about places to find add-ons for Microsoft Office, but there's also a wealth of free extensions and templates for OpenOffice.org's Writer word processor, Calc spreadsheet, and Impress presentation program.

Sunbird, Mozilla's calendar application, supports extensions just as Firefox and Thunderbird do. What kind of extensions work with a calendar? How about being able to get a weather forecast when you're setting up a golf date, or exporting your desktop calendar to a Web service?

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.

I've been using Firefox as my primary browser for so long that Internet Explorer looks strange to me on those odd occasions when Windows Update or some other automatic Windows setting opens it. There are lots of reasons Firefox is my browser of choice, not the least of which are the great free add-ons for the program that neither IE nor any other browser can match.
