I use Internet Explorer as my main browser. I have it locked down to prevent any problems and I don’t visit questionable sites. Steve Gibson uses it. That’s good enough for me. Besides, there are several sites that I must use every day and these sites have Active X controls that don’t work in Firefox.
There is one feature of Firefox that I like… the search tool. That little search box at the bottom of the page is great. More importantly, the F3 key works from within the tool. IE’s search tool is terrible. CTRL-F produces a pop-up box that always gets in the way. On top of that, the treasured F3 doesn’t work at all. Why have a two-key combination when one key will work great?
Then I found Inline Search from the guys at IEForge. This free IE add-on gives the same user experience during a search as does Firefox. There is no pop-up box and the F3 key (or shift-F3 to find previous) works just as it should in any Windows application.
In addition, there are Highlight All and Match Case options just like in Firefox.
The extension works in IE 6 or IE 7. If you are using Internet Explorer, this is one of those things you must have.
