It will be better if we can change the space between toolbar buttons that are placed on bookmarks toolbar and Add-ons toolbar.This review is for a previous version of the add-on (18.104.22.168-signed). This user has other reviews of this add-on.
OK, done for other toolbars too -> https://addons.mozilla.org/addon/cstbb/versions
Not sure, if this is also necessary for bookmark items on bookmarks toolbar, what do you think?
