It WAS one of my favorite Add-on's, but v1.7.1 doesn't work anymore with Firefox v55+.

You can find a similar, but still working Add-on here:

It works for me on 55.0.3 (32bit) together with Add-on "New Add-on Bar" here:

Hope it does it also 4U!

Doesn't work anymore in Firefox 29.0.
Before it was a 5 star add-on.

UPDATE: 2014-05-02: Thank you for your hint about "The Addon Bar" extension. Now 5 stars again and great support man!

I recommend installing "The Addon Bar" extension to restore the addon bar to Firefox 29. Every extension that uses it has been affected by the changes introduced in Firefox 29.
