HOW ADD A SECOND BOOKMARKS TOOLBAR ON V.57+?
I'm searching a solution because on the new version of Firefox many addons result obsolete. Many users need a second bookmarks toolbar and when they're asking help the team's answer is "Search an addon!". I used "multirow toolbar addon" but the developer announced that his job has been finished at v.56 thus I had to downgrade Firefox. Is there anyone who has an alternative solution?
