If Firefox View is already in the overflow menu, drag it from there to the main toolbar. Mozilla documents these placement options in its Firefox View instructions.

Check where the button went—and whether the window is private

Before resetting anything, look in both the overflow menu and the Customize Toolbar palette. Firefox View does not appear in Private Browsing windows; check the toolbar in a regular window if the button seems unavailable.

Open Firefox View without its toolbar button

You can still access Firefox View from the List all tabs menu at the end of the tab strip by selecting View All Tabs. If the Firefox Menu bar is enabled, you can also open it from Tools. Firefox View brings together open tabs, recently closed tabs, tabs from other devices, and browsing history. Tabs from other devices require signing in to a Mozilla account and enabling Sync.

Use Restore Defaults only if customization fails

As a later troubleshooting step, open Customize Toolbar and select Restore Defaults. Mozilla warns that this can switch vertical tabs back to horizontal tabs and reset the default theme, so use it only if placing the icon manually does not resolve the problem. Mozilla also describes Firefox Refresh as a recovery option for broader cases of corrupted toolbar settings; it is more disruptive than rearranging toolbar items, so reserve it for a suspected wider settings problem. See Mozilla’s toolbar customization guidance for the reset details.
