Well, it looks like the guys over at Firefox forgot to add the back and forward button. (I’ve noticed on the Firefox 3 Beta version and the official version now…)
It’s really annoying for people like me who like the back/forward button, here’s how to put that button back where it belongs:
First, goto View->Toolbars->Customize
Then simply draw the back/forward button on to any place you want to put it and press “Done”.
It’s pretty simple but a lot of people don’t know how to do it so this should help you get those buttons back.
