I suppose that's convenient, although I personally find it bothersome how open source so closely copies everything they can.

MSIE is ubiquitous enough to create de-facto standards. Why should you be surprised if competitors use those de-facto standards rather than require users to re-learn everything? The latter approach actually hurt Microsoft once upon a time converting people from WordPerfect to MS Word (back in the Word 2.0 days).

And, as has already been pointed out, Opera is not open source, but a proprietary commercial product.

Disagree, one of the best things Microsoft did was to standardize the ridiculous differences between the menus in WordPerfect and Lotus 1-2-3. While they were doing that, WP and Lotus were screaming "WE'RE STAYING DOS, FOREVER." LOL.
