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.
It’s probably the nature of the change, too.
Other stuff that people have been complaining about, like the massive backlash against baking in 3rd-party AI, won’t make the cut.
Relatively benign things like tab grouping are challenging, so despite being much more popular, the easier-to-implement AI features were given a fast pass to Release versions of Firefox.
