FIREFOX: How can I add/modify toolbars using the Add-on SDK last firefox (>firefox 55)
up vote 0 down vote favorite I've looked over the documentation for the Add-on SDK several times now and no where can I see how to create toolbars or modify existing ones. They have a tutorial on creating add-on bar icons but thats not what I want. Does the Add-on SDK support this yet? If it does, can someone link me to an example/tutorial. firefox firefox-addon share | improve this question asked Nov 10 at 16:40 user3194852 12 5 add a comment | up vote 0 down vote favorite I've looked over the documentation for the Add-on SDK several times now and no where can I see how to create toolbars or modify existing ones.
