Nope... Rated 1 out of 5 stars
It's a miracle! - somebody got this add-on to work for them! It goes without saying it still doesn't work for most. (And does not work on FF11 either)This review is for a previous version of the add-on (1.6). This user has 2 previous reviews of this add-on.
I use Geolocater 1.6 with FF11. Because I'm on Linux, Google Geolocation Service doesn't work. It's one reason of the Geolocater creation.
I have 4 geolocations created with Geolocater, wich I used on http://maps.google.fr or http://www.flickr.com/map/ .
Geolocater 1.5 has a bug on FF10 and 11, Geolocater 1.6 has been developped on FF10 and tested on FF11. If you would like to help, could you say what it doesn't work ?
