This Has Toolbar Buttons Rated 5 out of 5 stars

I have used this for a long time with no problems. Provides several button options for just about every need.

Note that Florian Wolk's add-on pointed to in No Nothing's review does not have toolbar buttons; if using keyboard only is what you want then it might be worth your time to check it out.

This review is for a previous version of the add-on (0.5.0.1).
