this is a new gecko browser. it's based on Firefox but at the moment it's inbetween alpha and beta stage development, so it will probably be buggy. the main difference between this and FF is it's aimed at "web 2.0" - AJAX, social bookmarking, bloggers, Flickr etc. maybe you should be careful with your bookmarks if you try it, there's a chance they might not be stored locally, but at del.icio.us? but i don't know. here are some screenshots: http://www.ctrlaltsuppr.com/sujet19991.html http://www.flock.com/ EDIT i just read this link and it says it's based on Firefox 1.5 - down the page under "Disclaimer". http://www.paulstamatiou.com/2005/10/21/flock-under-those-feathers/ so maybe it's not so safe, i've no idea, but i don't think i'll try it even though i like alot of the sites it works with. it's just that alot of them are to do with sharing things and that might not be safe.
