> Mozilla seems to disagree, as the Megabar change has shown. Not only have they introduced a meaningless but annoying change, but they actively want to prevent people from disabling it. The reason they rewrote the URL bar code was that the previous version was written using XUL / XBL, and they are in the process of removing XUL / XBL from the browser. Writing a new version while leaving the old version around would defeat the entire purpose, which was deleting the old code to reduce technical debt. Now, my personal preference would have been that they rewrite it without re-designing it - but "actively prevent people from disabling it" is a very inaccurate description of what happened.
