With the fix for bug 62495, Mozilla now has the best URL bar editing behavior of any browser. Single-click still selects the entire URL bar (unless you turn it off). Even better, selection works as expected. I find it hard to believe that Mozilla 1.0 shipped with very broken right-click context menu behavior (bug 96446) but that’s fixed now too. I’m glad to see these basic usability problems getting fixed. It’s about time. The URL bar has had broken behavior since 2000 or earlier.
