Seems like you may be using an addon to move the Firefox button? Can you disable that and see if you have the same issue. If not list what addons you have so I can test.
I don't know, My addons list: ########################################################### Adblock Plus Add-on Compatibility Reporter AutoProxy ClickCutter AutoCopy Download StatusBar DownThemAll! FireGestures FlashBlock Pentadactyl Scriptish (with several user scripts, but do nothing with FF UI) ############################################################ There is only the offical theme beside TwentyTen2.
BTW... I love the theme... can´t think of any better
#appmenu-button > .button-box::before {
content: "Firefox" !important;
}
#appmenu-button > .button-box::before {
font-weight: 800 !important;
content: "Firefox" !important;
}
When FF is maximized, tabs are not set on top, see here:[link]
when FF is not maximized it appears beautiful, see here:[link]
