Its possible that Firefox might go for another big UI change in the future. This time, its going to be really unique and feature rich. Have a look at the screenshots I attached… You’ll see what im talking about…
No big orange Firefox button… A cool iconized menu… Rounded tabs… Pinned sites and many more… The new mockup seems to be really nice. But Im thinking… Isn’t it a bit cluttered? Don’t you feel like too much? What do you say?
Please note that these are only mockups posted on the Mozilla wiki. They are not finalized yet!
