Oh, that's just the change that Firefox made for its linux build, due to the different interfaces for different operating systems (such as pasting with middle click, and autoscroll being off). If you go into about:config, you'll find a key called "browser.urlbar.doubleClickSelectsAll", and it should be true in linux but false in windows. Also, you can still move stuff around on the toolbars, just like in windows.
