Firefox browser is known and loved for the availability of wonderful add-ons which add up many features that are not directly available in the default browser. But when you are using many add-ons you can’t just spend some additional time to update them if there are changes made by their developers.

So, there is a firefox add-on which would do the job for you to check for the updates of plugins automatically, and also can update those pending ones if you change your settings. It is called Update Notifier. Here is a short description -

Notifies you when updates are available for your extensions and themes. Allows quick access to your extensions and themes and the ability to check both types for any updates. Easily configurable for automatically installing updates when available and checking for updates when Firefox starts.

It never annoys a firefox user, as when the updates are available, a small tooltip appears on the right top showing which all add-ons need to be updated. And then you can complete the process with your commands.

This add-on works for the firefox versions from 1.5 to 3.0 and the developers are yet to release it for the 3.1 version. And this add-on does not only have the option to check the other extension updates, but also if the firefox themes have any updates to be done, it does that too.
