If you go to Customize mode, there is "List all tabs" button at the right end of the tab bar. How am I supposed to use it? It is not interactive, I can't move it, it is not listed in "Additional tools and features" either.
Sorry for my poor English.

It automatically displays - and works - when your tab bar overflows (i.e. you have more tabs than the available space allows to display).

I wonder if there is any talk of delaying Web Extensions for a few versions, to iron any outstanding bugs

Assuming it doesn't get backed out, looks like OOP WebExtensions are being enabled in tomorrow's nightly.

Strange issues that I'm not sure about:

1) (eg: ) is left-aligning the main content if the browser is above a certain width, even though it used to be centered.

Using the dev inspector, the main div (#main.ciu-main-wrap) has margins set as "0 auto", which is corroborated with the computed results which show the left and right margins to have values of 'auto'. But for some reason it's not being displayed the way that should work.

This occurs even with a fresh temporary profile.

If I disable the body's max-width (otherwise set at 81.25em), the center content stretches across the entire screen, and the margin auto effect seems to be in place (with the 'margins' being padding on the body).

Basically, it feels like it's calculating the default width, applying the auto margins, and *then* capping the width at the max width, which I would expect it to calculate the max width, and *then* apply the auto margins. Am I making an error in my assumptions? Do other people see the same results? Is this a bug?

2) According to ... ified_file there should be a little icon in the dev tools window to pretty-print the javascript there. It should be in the bottom right corner. I'm not seeing such a button. Has it been moved elsewhere, or has it been lost in the Quantum Flow rebuild?

Backed out on inbound, never made it to m-c, so won't be in today's Nightly.

I don't dig the white title-bar when Firefox is out of focus on default theme. It's distracting and annoying. :(
Especially on Windows 10 where you can scroll when the browser is not on focus.

I'm trying to find the style code for this area (dubbed as the Navigation ... button) but having difficult. Does anyone know? I want to change the background color of it using Userstyle (specifically a global Stylish script).


Thank you
