I use Firefox as it is stated in the $subject. Nevertheless there are still too many contents (I'm talking about mostly videos) on the web that needs flash. This is what I use for it:
So in this way I can download/view with VLC ex.: youtube videos. But aren't there a better way to do this? To get the life without flash easier?
And no, enabling html5 on youtube... doesn't help, because it looks like very-very-very low percentage of the youtube videos are viewable in html5..
UPDATE: so I don't want to run videos inside my browser. They will be always slower compared to a video natively played in ex.: VLC. Also AFAIK it's much safer to have empty about:plugins and play the needed videos in VLC.
