Review for Toolbar Buttons by Bill Dawkins
Rated 5 out of 5 stars
Has many useful buttons.
There are buttons for clearing data (history) and disabling/enabling cookies and those are incredibly useful for me. I've been wanting those buttons for years.
The cookies button even has three modes: on, no-third-party, and off.
I don't know if it's possible but it would be great to have an additional clear-data button that just clears the data (history) with one click instead of bringing up the confirmation prompt.
Minor gripe: After installing the add-on, I enabled some of my other add-ons and their toolbar buttons were gone. I had to add them back to the toolbar.
