Re: disappointed that the world of linux remains so clunky
Just because you don't want to learn, doesn't make Linux clunky.
It's trivially easy to download Seamonkey from the Mozilla site, and run it. No clunkiness required.
Or add a PPA to install it through Software Center. It's a one-liner.
I try to treat the cause, not the symptom. I avoid the terminal in instructions, unless it's easier or necessary. My instructions will work within the Ubuntu system, instead of breaking or subverting it. Those are the three guarantees to the helpee.
