Firefox users criticized the permanent ‘List All Tabs’ button introduced in version 131.0, leading Mozilla to make it removable.
The button, designed to manage hidden tabs and prevent add-ons from hiding them, received backlash for being unnecessary alongside Firefox View.
Mozilla responded with a fix in version 131.0.3, allowing users to remove the button through toolbar customization.
Agreed. Being able to customize all elements of the top bar is one of the great things about Firefox.
I don’t see a reason why it shouldn’t be possible to remove newly added elements. Even the “Open a new tab” button can be removed, as well as the recently added “View recent browsing across windows and devices” button.
