It took a while, but someone finally released an add-on that fixes the most annoying part of searching pages in Internet Explorer. The Inline Search for Internet Explorer add-on replaces the modal Find dialog box with a bar that sits at the bottom of the page, exactly like the one in Firefox. As you type in your search term, it locates the first instance on the page immediately. You can find the next or previous instance using the buttons on the toolbar or by pressing the up or down arrow keys. You don’t have to click a Find button or close the dialog box when you’re done either.
I’ve been using IE7 more and more and generally prefer it to Firefox these days. I still keep Firefox around for the small number of pages that just won’t work properly in IE7.
