Exactly. This guy is saying "my windows manager sucks, why doesn't Mozilla do something about it"
I'd like an excuse to use Firefox again, but they've just given up on new UI functionality and I'd miss out on a lot by switching away from Arc.
Not really - see response to sibling comment.
Right, so your windows manager doesn't support selective tiling, why doesn't Mozilla do something about it??!
Because I don't want to manage 4 windows tiled like 4 panes - I want to manage a single window with 4 panes. What happens if I close one of 4? Now I have a gap that an related or unrelated window will fill or it'll be a wasted space - this doesn't happen in case of split panes because the other panes will expand to take the space. I logically group my work in separate windows - so in a split pane setup, once I'm done, I close a single window instead of having to close separate windows one by one. If I have a 4x2 grid in your tiling-WM-is-the-truth world, you expect me to close 8 windows one by one?

Sure, if you lack imagination, everything must be feeling like a distraction.
If code editors are indicative, yes some power users tend to like a tiling window manager bundled in the app. So you may be right but I think it's out of scope for Firefox which targets the masses and it's definitely off-topic here.
Yes I don't want repeated toolbars because they are waste of space when they are repeated in each window/pane - having to switch browsers isn't the point, the discussion is about what Firefox can do to improve its user's life (even if everyone doesn't expect/need split panes in their browser, some do).
