Apparently, MasterPages aren’t limited to ASP.NET 2.0. This article, ASP.NET.4GuysFromRolla.com: Creating Template-Driven Web Sites with MasterPages describes how to implement it in ASP.NET 1.x.
I’m not sure it’s feasible (won’t create more of a mess than it solves) to implement on our existing ASP.NET site but it will definitely come into play as we transition to ASP.NET 2.0.

The problem occurred when I tried to create a rollovers effect on a Suckerfish dropdown menu for my revised TAI layout. The sub-menu pops up over a section that had a background image. The sub-menu background was supposed to show a screened version of that background (like looking through a transluscent screen.) It worked fine in Firefox and Opera but I couldn’t get it to work in IE. And I was using an alternate image on the li hovers to simulate the transparency. The problem occurred in IE because it positions the background image from the origin of the li instead of from the origin of the containing div. I wasn’t able to work around this. Instead, I turned to utilizing PNG images for the background, because PNG supports transparency. This came in useful for a problem I was having, Discussing: Cross-Browser Variable Opacity with PNG: A Real Solution: A List Apart. IE requires a hack in order to display PNG files with transparency. I modified the solution in the article to avoid javascript and simply put the necessary attributes in the inline stylesheet.

More Firefox hacking: Making Firefox Handle Multiline Pasted (”Broken”) URLs (by Jeremy Zawodny). I wonder what else one can make Firefox do if one just knew where to look.

Coming upon this link, showing how to prevent pop-up windows in Firefox is timely since I’ve been noticing pop-up windows getting through lately (www.m-w.com.) Apparently developers have been taking advantage of the Flash plug-in to launch pop-up windows. By adding a value to Firefox’s config file it disables pop-ups from plugins.
There’s further info at on Mozillazine (link found in comments to above article): say goodbye (again) to pop-ups! which has an extension (in beta) that takes care of these sort of pop-ups and pop-unders.
