There should be a way of using an HTTP header to turn compatibility mode on and off. At present it is triggered by transitional DTD, which is _bad_ - transitional dtd does not mean 'Break my pages please'. The fact that transitional dtd triggers compatibility mode does not make those bugs less buggy. In fact, it is causing me major problems because the hacks that I use to workaround Netscape 4's bugs no longer work with Mozilla, and so I have annoying display glitches in Mozilla. The most important thing is that since 'compatibility mode'=='bug mode' (every supposed compatibility mode feature is actually a bug), there must be a way to disable it. I suggest a Compatibility-Mode HTTP header.
For the user ther should be a two-state (check marked) menu item in the View menu that would both indicate the mode and let the user change it (temporarily) if Mozilla has guessed wrong.
I agree with this bug, but I believe it duplicates bug 31933.

Bug 42525 is about being able to get standard layout for transitional documents. You may want to add your comments to that bug.
This is really a dup of bug 34135.
