In this test file, IE will respond with L and X, as expected, since they use document.all.whatever. However, there is no duplicate function for Mozilla, using a vast number of different combinations of properties. Reproducible: Always Steps to Reproduce: 1. Get test.html file. 2. Put mouse over each of the sentences. Actual Results: Nothing happened. Expected Results: At least one of the sentences should disappear or resize. This is a severe issue with the capabilities of Mozilla's JS interface with the DOM model. If you can't reference to an object on an HTML page and change a style type for it, what's the point? That's about 90% of the purpose of the DOM.

getElementById() is a function, to be used as: document.getElementById("ccc").style.font = "whatever"; getElementsByName() (note the "s") is also a function that returns a list; typical usage: document.getElementsByName("aaa")[0].style.font = "something" I suggest giving http://www.w3.org/TR/2000/REC-DOM-Level-2-Core-20001113/core.html#i-Document and http://www.w3.org/TR/2002/PR-DOM-Level-2-HTML-20021108/html.html#ID-26809268 a read.

Hell, I tried brackets (which Mozilla would translate back into a.b form), but didn't try ()s. Anyway, with the changes, B/D and N/P work with Mozilla. Unfortunately, the W3 didn't help much (I already consulted that), but I'm sorry to bother you.
