Hello, click on the 3 line, or hamburger menu, then click on Customize Firefox, drag the bookmarks menu to the toolbar like in the attached screenshot.

Alternatively, press Ctrl + Shift + O on your keyboard to quickly access all bookmarks.

If this solved your problem, mark as solution.

Thanks however, once done there still in nothing in tookbar as before and nothing in bookmarks and nothing to retore. Had no issues before firefox updated. Any help would be appreciated.
