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.
Ok, that makes sense.
I still don’t see why they (Mozilla) felt the feature was needed, since if you’re installing an addon to manage tabs, that’s all on you, the user.
