Rated 2 out of 5 stars
5 stars if you have Firefox 3.5 or older.
Probably one of my most used add-ons. The left-hand sidebar is a fantastic convenience for keeping up on your contacts & favorite groups. Beats the hell outta having to page through your contacts page.
But w/ the release of Firefox 3.6, the add-on freezes the browser. Thus rendering Flickrfox useless.
Hopefully Phil will come up w/ a fix soon. Already feeling out of touch w/ my contacts list & it's only been a few days.
