Thank you Rated 5 out of 5 stars
Does exactly what it's supposed to and it is so useful! When I upgraded to Firefox 3 I was shocked to find that Tab Browser Preferences wasn't going to be supported in all likelihood. I just can't stand opening a blank window instead of my search engine when I open a new tab and modifying user.js didn't seem to work as suggested in a bug report somewhere. This is the main feature I used Tab Browser Preferences for but I'll also miss some of its other features if I can't get user.js to work with them as well.
Thank you again.
