Version 1.9.5 working in FF16.0.2 Rated 5 out of 5 stars
In the past I've always tried to manually download videos but I'm just getting tired of that. NetVideoHunter is simple, unintrusive and the preview capability is a nice if unessential feature. One option I would like to see in the future is to be able to set the default quality.
The lastest version (1.9.5) works fine for Youtube in FF16.0.2 for me.
