Not working in Firefox 21...? Rated 5 out of 5 stars
Hi Paolo, it seems that the add-on stopped working in Firefox 21. Upon launching another profile, the message is "Unable to file executable".This review is for a previous version of the add-on (18.104.22.168).
It's fixed in 22.214.171.124 version, you can find it here https://addons.mozilla.org/it/firefox/addon/profileswitcher/versions/
