Hi BryceCornwell, did you just update from the Extended Support Release of Firefox 52 (ESR) to Firefox 60 ESR? If you were using Tab Mix Plus or another extension to modify your Bookmarks Toolbar, you will need to switch to a new method because starting in Firefox 57, add-ons can't make that kind of change to the interface. On my page below I have links to two different solutions that are implemented through a userChrome.css file. If you are new to that, we can help some, and there's also a useful subreddit. * https://www.userchrome.org/what-is-userchrome-css.html#multirowbookmarks * https://www.reddit.com/r/FirefoxCSS/
