Saved links can seem to disappear when their row vanishes from the browser. Firefox bookmarks toolbar missing is therefore a display question before it is a data-loss diagnosis. Check where the bookmarks can still be found, then decide whether you need to reveal the toolbar or investigate recovery.
Quick Answer
Check the Bookmarks Toolbar visibility and choose Always Show if the row should remain on ordinary pages. A new-tab-only setting can explain why it appears intermittently. This is an R0 fix; verify whether saved items are still in the library before restoring a backup or treating the display as faulty.
🔖 Test the visibility mode first
Firefox provides three useful choices: keep the row visible, hide it, or show it only on a new tab. Open a new tab and an ordinary webpage to compare the behaviour. That small test can reveal a deliberate visibility rule without changing any saved link.
Use the toolbar customisation area or the context menu on an empty part of the tab bar. Avoid clicking a specific tab when you mean to configure the browser furniture around it. Once the row appears, inspect a familiar bookmark rather than immediately rearranging everything.

🗃️ Confirm whether the items still exist
Look in the bookmark library if the row appears empty. There is a meaningful difference between saved data that is out of view and data that is actually absent. Backup restoration belongs to the second situation and should not be your first response to a hidden strip of controls.
If several browser controls have disappeared, check whether you are in full-screen mode. Switching to another monitor will not necessarily change a browser visibility preference. Compare gaming monitors for physical workspace only after the current window behaves as intended.
🖱️ Finish with a simple navigation check
Open one saved site and return to the page you were reading. The useful result is predictable access to links, not merely a row appearing in a screenshot. If the toolbar changes again, note whether it happened after a new tab, window-mode change or browser restart.
With gaming mice, distinguish an unreliable physical click from a menu you opened on the wrong part of the window. Test an ordinary button before deciding you need replacement hardware. Keeping the diagnosis narrow protects both your time and your bookmarks: first make the controls visible, then investigate missing content only if the library confirms a problem.
Frequently Asked Questions
Why does the row appear only on a new tab?
The toolbar may be set to Only Show on New Tab. Choose Always Show if you want it on normal pages too.
How do I show it?
Open the toolbar customisation controls or right-click a blank tab-bar area, then choose the Bookmarks Toolbar visibility.
Have my bookmarks been deleted?
A hidden toolbar does not establish deletion. Inspect the bookmark library before taking recovery steps.
Can full-screen mode hide controls?
Yes. Check the current window mode if normal browser controls are missing along with the saved-sites row.
Should I restore a backup immediately?
First establish that the saved items are actually missing. Restoring data is a larger action than making a toolbar visible.
Do I need a larger monitor?
No purchase is needed to show the toolbar. Consider physical screen space only after the browser visibility preference is correct.
