Rated 5 out of 5 stars

I've been using Navigational Sounds for years and I absolutely LOVE this add-on! Aural feedback is really nice, the only IE innovation I missed when I first moved to FF.
Thank you James!

For those of you having problems installing any version of Navigational Sounds due to FF saying it isn't compatible, try the following:
Find your FF profile (\users\\AppData\Roaming\Mozilla\Firefox\Profiles on Vista+). In the extensions folder will be dirs for each of your add-ons with random character names. Determine which one belongs to NS by viewing the install.rdf file. Modify the line that begins with to a value that includes your FF version. This a common 'fix' that often has to be applied to various add-ons when a new version of FF comes out.

This review is for a previous version of the add-on (1.2.0).
