Tiny Menu Alternative. Rated 5 out of 5 stars
Here's an alternative for those who don't want to wait for Tiny Menu to be updated.
You will need the following addons:
Personal Menu: https://addons.mozilla.org/en-US/firefox/addon/personal-menu/
Using Personal menu, remove all of the menu options and add "file, edit, view, history, bookmarks, tools, help" if you want a simple drop-down menu. Feel free to customize to your liking.
Download the following stylescripts and add them to Stylish.
FF4 Menu Button with Icon: http://userstyles.org/styles/45532/ff4-menu-button-with-icon-tabs-in-titlebar-0-4-4
Select "No, I only need the modified Firefox button" and have it activated at all times.
Move all of your navigational tools (your address bar, back/forward buttons, etc) from the menu bar to the navigation bar. Place the modified Firefox button anywhere on the navigation bar.
Install Hide Menubar: http://userstyles.org/styles/26233/hide-menubar-obsolete-in-firefox-3-6
OPTIONAL:You may also want to install the following addons.
FF4 - Increase Visible Space: http://userstyles.org/styles/44801/ff4-increase-visible-space
Firefox tab bar - hide scroll buttons: http://userstyles.org/styles/45330/firefox-tab-bar-hide-scroll-buttons?r=1300402765
The end result will be a clean, space-saving navigation bar. The custom firefox button should be invisible until you mouse over it, sparing you from having your eyes distracted by its garish orange color.
Hope this helps.
