Review for Toolbar Buttons by Wirewox
Rated 5 out of 5 stars
While now apparently unsupported, this still contains some excellent working buttons and can replace a number of individual further extensions. Once installed, you will find the "Sort and Search Customization Dialogs" addon very helpful!
This review is for a previous version of the add-on (1.0.1-signed.1-signed).To create your own collections, you must have a Mozilla Add-ons account.
