SUGGESTION: add a hotkey so the menu can be opened in fullscreen mode. Here's some XUL code additions that will do it:
<commandset id="mainCommandSet">
<command id="cmd_mainMenuPopper" oncommand="if (window.fullScreen) {document.getElementById('appmenu-popup').openPopupAtScreen(0,0,true);} else {document.getElementById('appmenu-popup').openPopup(document.getElementById('appmenu-button'),'after_start',0,0,false,false);}"/>
</commandset>
<keyset id="mainKeyset">
<key id="key_menu_popper" modifiers="alt" key="`" oncommand="document.getElementById('cmd_mainMenuPopper').doCommand();"/>
</keyset><button id="appmenu-button" type="" command="cmd_mainMenuPopper"/>
<script>
<![CDATA[ (function () { document.getElementById('main-window').insertBefore(document.getElementById('appmenu-popup'), document.getElementById('titlebar')); })(); ]]>
</script>

This was just a quick and dirty change for my use, so it defines Alt - ` to pop open the menu; but you can change that or even put in an option to define it.

I'm not sure whether the missing Firefox Button will be brought back or not in the final version of Firefox.If not, I will try to make a workaround about it in the new version.

problem with version 5.0 Rated 5 out of 5 stars

I've been testing version 5.0 and it works absolutely great... but there is one problem. Whenever you hide the menu bar, it inserts a bookmark menu button on the right end of the bookmarks toolbar. I don't know if this is a bug or a feature; but if it's a feature could you add an option to not have that button inserted there.

It is the feature of Firefox 4 itself: Suggests you a Bookmarks Button when Menu Bar is hidden. You may simply remove it by "View --> Toolbars --> Customize", you can find it is at the end of Navigation Toolbar.

This addon occasionally breaks the toolbars in Firefox 4 beta 7. To see this in action, install this along with the PDF Download addon... that combination breaks the toolbars every time. But Personal Menu seems to cause it occasionally by itself when installing other extensions or restarting
