Rated 5 out of 5 stars
Still a great extension, clearly deserving a five-star rating, in spite of the fact that I had to revert to an older version in order regain the lost ability to disable/enable it quickly, directly from the statusbar.
RefControl does efficiently everything one needs, including many of the things other previous reviewers on this board have claimed it does not do.
RefControl 0.8.16 no longer displays the options menu when one left clicks the status bar. This is a critical feature for vimperator/pentadactyl users who choose to live without a "navigation toolbar" and without a "menu bar", and who try control everything from the statusbar or the vimperator commandline.
I hope future versions include a quickly accessible enable/disable option, if not directly from the statusbar, perhaps from the context menu.
