Support Volunteers can't make changes to Firefox and have no say in what is being done. If you turn on Firefox Menu Bar with a right click at top of browser would be the fastest way to get to all your bookmarks. As well 1 extra command in History for some reason. Bookmarking is simple with the Star, the 3 Dot Menu is accessible. If you Customize can drag out Library and put it where you want. https://www.howtogeek.com/333110/how-to-customize-firefox-quantum-and-remove-the-white-space-around-the-title-bar/ You can try this https://addons.mozilla.org/en-US/firefox/addon/bookmarks-manager-and-viewer/ or search from there for Bookmarks. Or if remember a addon name https://mozilla.github.io/extension-finder/ To submit suggestions for new or changed features, may I suggest: Feedback: https://qsurvey.mozilla.com/s3/FirefoxInput/ Please let us know if this solved your issue or if need further assistance.
