The ability to theme and extend firefox through plugins is one of the most powerful features that the browser has to offer. A lot of the addons that I install I end up deploying to more users then myself and luckily firefox has a neat way of allowing you to install additions into the global config. Just use the
–install-global-extension
or
–install-global-theme
flags. An example would be
firefox –install-global-extension /tmp/test-extension.xpi
Now every user will have test-extension installed in their own firefox instance!
