Rated 3 out of 5 stars
May be useful for those wishing to program their own buttons, however this addon conflicts with Toolbar Buttons, an addon I find to be more useful. So I dumped this one.This review is for a previous version of the add-on (188.8.131.52).
Toolbar Buttons conflicts
Custom Buttons² version 184.108.40.206 was tested with Toolbar Buttons in Firefox version 3.0.6 and we found no conflicts. We were unable to test for conflicts in Firefox version 3.2a1pre because Toolbar Buttons is not compatible with that version at this time.
Please contact us at http://custombuttons2.com/ and share the conflict you are having so we may fix it.
