PlasmaNotify for Firefox 4 and 5
I just upgraded my Firefox addon PlasmaNotify, so that it can be installed on Firefox 4 and 5. I committed the changes to Mozilla so that the Addon should upgrade itself within the next view days. I promise to be quicker on the next Firefox major releases!
Impatient users may download the addon in advance over here.
The addon itself is inteded for Linux and integrates the Firefox download notifications into the KDE Plasma notifications.
