So for some of you, this will be old news, but it was new to me.
In times (not so long) past, a major complaint concerning Linux was its plugin support for browsers. Namely, if you went to a website that needed, for example, QuickTime... Firefox would inform you that a certain plugin was missing and that's about as far as it would help. Installing the plugin (and anything else needed) would fall to the user, and sometimes that task was not easy.
Ubuntu continues to make the user experience better in their distribution, since they apparently have a solution to this problem. Ubuntu provides a package program called Ubufox which will assist users in automatically install plugins as necessary. It's a simple "Enter your password" and click Next solution, and doesn't get much smoother than that. I used this for the first time today and I didn't even have to restart Firefox. It just worked.
I haven't found something this nice since they automated Nvidia driver installation with the (KDE/Gnome)-Jockey program. Nicely done once again Ubuntu.
