Mozilla is using a larger underline, for larger text and thinner line for smaller text. This is not the case in Internet Explorer, which I believe does the right thing. We should have a 1-2px line under *all* underlined text, including links. No matter how big the text is, it should always have the same size of the underline.
Created attachment 21668 [details] How IE (from the left) and Mozilla (on the right) handles underlining of text.
Created attachment 21669 [details] This also looks quite interesting in Mozilla, how text in various sizes - all underlined - looks.
Erik, is this yours?
See bug 1777.
Sheesh! That's an old bug, almost 3 years. I suggest we make bug 1777 dependant on this one.. or is this a dupe? I'm confused..
sigh, old bugs that remain complicated and unfixed. vrfy dupe.
