Hi Stephanie, do you mean on Firefox's Bookmarks Toolbar, or one of the other toolbars? Either way, I suppose, changing the display isn't a built-in feature. It would have involved either:

• An extension, or
• Creating a custom style rule in the userChrome.css file

Since an extension is more common, you could check what you've got on the Add-ons page. Either:

• Ctrl+Shift+a (Mac: Command+Shift+a)
• "3-bar" menu button (or Tools menu) > Add-ons

In the left column, click Extensions. Then cast a critical eye over the list on the right side. Does anything look relevant?

Hi You have fixed it - thank you so much!

Just one more question - is it possible to increase the size of the bookmark toolbar to have a double row? If not then that is cool - I would rather have my toolbar fixed and single than a jumble of tiles!!

Best Regards Stephanie

Hi Stephanie, there's no built-in way to expand the Bookmarks Toolbar to two rows. You can create a folder and move less used but still highly relevant bookmarks into one that remains visible and doesn't require using the overflow drop-down. Otherwise, you would need an add-on (possibly a different one, or possibly the same one with some adjustments to its options).

Hi That is great - thank you so much for your help!

Kind Regards Stephanie
