BuildMonitor v0.9 has been released, you can get it from the usual place.
The most useful improvement from this release is the ability to add new feed via right click menu of a link. Other improvements include the ability to remove the feed via status bar right click menu or from preferences menu. It’s also now possible to rearrange the order of the feeds via preferences menu.
I made a quick video (using recordMyDesktop) showing how easy it is to monitor Hudson feeds using the Firefox Add-on.
On l10n front, BuildMonitor has been translated to Japanese. Thank you, Sogabe-san.
I had to borrow a laptop with Windows to take this screenshot. I think Firefox 3.0.3 locale switching on Ubuntu is borked, the web pages do pick up the correct locale, but the add-ons ignore it.
