At long last the one thing which I really missed when moving from Opera 7.5 to Firefox 1.0, has been developed as a extension. Opera had this great way of remembering sessions even when your machine had crashed or you had closed the browser by mistake. Now SessionSaver does the same for Firefox. I'm the first to rate it and I had to rate it 5 stars. I believe theres enough extensions to make up for almost every feature in Opera. I just need Firefox to be as quick and slick as Opera now.
A while ago I highlighted a load of extensions I used in Firefox, well this my current selection used across the 5 different machines I use day in day out.
