I understand that Chrome has chromify-osd, an extension that lets it use notify-osd for notifications. Is it possible to customize it such that it works for Firefox as well?
There is a script made by Marco Ceppi and modified by George Edison that allows Firefox to use Notify-OSD.
For Firefox to use Notify-OSD, you need to have Greasemonkey extension installed in Firefox. After that, you need to download this script.
You also have to download NPAPI plugin and copy them to your ~/.mozilla/plugins/ folder and restart the browser.
After all that, run the following command in a terminal:
sudo ln -s /usr/lib/x86_64-linux-gnu/libnotify.so.4 /usr/lib/x86_64-linux-gnu/libnotify.so.1
You now should have Firefox using Notify-OSD for displaying notifications.
