missing bookmarks icons + crazy tabs!!!

[guycruls]

I used to have the bookmarks icon next to the 'next-to-homepage' icon (the little house). When I right-click and drag the bookmarks icon next to the little house, it goes there alright, but when I close and restart Firefox, it's gone.
Also, when I click on the little house, a new tab opens, and end up with a multitude of tabs. Firefox used to be great, but I'm not far from smashing up my laptop to smithereens!!! Arrgh! Help!!!
