Very Useful - Hide Title Bar, small and efficient. Rated 5 out of 5 stars
Tip: Turn on "Caption in Status bar" - then you can remove the caption button from the top. Cleaner look and good use of status-bar with no loss of functionality (hover over a link and it shows up as usual). Cannot praise this extension enough. The "M" Button can be lost in a dark theme.This review is for a previous version of the add-on (0.7.6.1).
