To chrome/chromium's credit, these are the browsers that promoted a less clutered menu (orange firefox toolbar was introduced two years later).

I don't remember which vendor introduced the one-click star button to bookmark pages but it's a good idea too.

I also remember that the ie7 rss/atom summary page is still more elegant than mozilla.

I am sad no other mozilla software is enjoying the same success as firefox. All the "lab" experiments are in one way or another incorporated into the browsers but they never get established as perenial applications (it might not be the objective though). I still believe there is room for a easier-to-use xul application toolkit and a better "communication" hub aka thunderbird.
