My ideas:
These ideas have been posted on Mozilla's site because Mozilla offered the most open browser development process. However, since I care more about the future of the web than I do about loyalty to any particular brand of browser (and I have not been particularly impressed with the leadership of Mozilla in the past 3 or 4 years), all my ideas are also open to Palemoon, Microsoft, Google, Opera or any other browser developer!
