> In my mind, this is a good thing. Browsers should do one thing well. ... As a *nix guy for three decades, I simply cannot escape the "do one thing well" paradigm.

As with every tool, what counts as that “one thing” is entirely subjective, in the eye of the beholder, highly personal, often arbitrary.

Why should Firefox support tabs? Shouldn’t my window manager do that? Why does a browser keep track of history when my operating environment should keep track of a history of things I’ve seen recently - documents, files, URLs?

It’s the exact same debate about whether programs should do any of the things that can be handled by tmux / GNU screen / readline / whatever.

For you, the “one thing” browsers should do maps exactly to what you think counts as “one thing.” To others, that might include Firefox’s RSS support, and leave out something you consider essential, calling it “bloat” and against the spirit of Unix.
