Another boneheaded thing they did with tabs was replacing the favicon with a loudspeaker when the tab is playing audio[1], instead of displaying the loudspeaker at the end of the title or overlaid like when you pin a tab.

Now I have trouble finding the tab of a YouTube video among a lot of tabs because I can't just look for the YouTube favicon. It was clearly better before, and that should have been obvious to any UX designer worth their salt.

They're clearly not asking "What is a good interface?", they're asking "What is a shiny interface?".

Ah, that explains how I've inadvertently muted tabs several times over the last few days, when I've never done that before.

I won't be switching to "normal" mode as long as I use Firefox in a smaller window, displaying chat applications, videos, or whatever as I go about other things.

Mozilla seems to assume people will use Firefox in a maximized window, which isn't true for me 90% of the time, but I am getting exceedingly tired of having to fix the interface with custom styles every 2-3 releases.

Nils a part of learning to be a good programmer will be learning to be a good human, too.

Stuff like this should simply be rejected. Design that is unusable and tailored to look "clean" on a calibrated monitor is not design at all.

Notably, those changes cannot be adjusted with the options. Even if they care about the simplicity of the settings panel more than the experience of the power users, adding a setting to about:config would be the right choice.

I still use Firefox on the daily basis because I wouldn't want the pages I develop work only on Chromium. [putting on a conspiracy theorist hat] However, the biggest payer of Mozilla is not users, but Google. It is in their best interest to keep Firefox in a state that has a small share of the market, and yet does not let the regulators claim that Google holds a monopoly on browsing. The decline of FF usability is sad but not surprising.

I still use FF, but it is no longer the easy to use yet deep power tool that vim/emacs/imagemagick are.

You said that you didn't, and neither did I. I just don't know if anything but Chromium would be sustainable, and I still don't want to switch to Chromium. If anything, FF profiles are still a reason to use it. Even though I don't really believe FF is still much better than Chrome in terms of privacy and such (well, TBH, it still gives me peace that I can disable some stuff in about:config I almost surely couldn't in Chromium: I'd need to investigate, and it doesn't help that Chromium users generally don't bother themselves with such issues). And it hardly is in terms of actual browser technology. I didn't check if all plugins I need work under chromium, but I assume they would, since most non-major stuff was broken in FF anyway, and major stuff tends to have even better support in chromium nowadays.

Vivaldi is still behind FF84 in three notable areas: video/PiP (why they dim the video when the mouse is over the pip window I have no idea), occasional tab thread instability (requiring esc press to unlock), scrolling physics.

But vivaldi also makes up for it with other features. Mouse gestures are a godsend and improve browsing immeasurably (e.g. I made an up-left-right gesture to bring down bookmarks bar). I briefly hooked into a fake email server so I could enable the built-in RSS features and that's going places. The stacked tabs are solid, they seem to be taking great care in getting them right.

Another thing I didn't like after upgrading to FF89 was overscrolling, but fortunately once I figured out the term itself (which took a good bit of Googling as the effect is hard to describe) it was easy to disable.

Recent updates to Firefox have made me pretty unhappy with Mozilla, though. Really not a fan of major UI changes happening between updates with no warning. They should make it easier to revert to the old UI.

I'm still using Firefox 68.11 on Mobile because the new Firefox mobile engine still doesn't support most addons/extensions... what a joke.

Then I came across some threads about the new UI expecting everyone to be congratulating Mozilla on a job well done but instead were just on fire with vitriol about how it may be the worst thing to ever happen. I didn't even notice the dozen of tiny changes all of these people found.

I'm not a tab slouch either (typically 250+ tabs open accompanied by the shame and anxiety that brings) so I'd expect to be pretty sensitive to even minor inconveniences added to the tab bar but apparently not.

If modern UI theory is to make it as simple as possible and no simpler, then it seems we're straddling the line where important information (e.g. which tab is which) is now being lost.

Hoping some day someone builds a playground so it's easy to build/customise interfaces through a GUI as I find it a bit of a chore to get things tweaked exactly right!

In the meantime it's worth noting you can use remote debugging[1] to live edit the interface.

You can also add this

    .tab-secondary-label { display: none }

Increasingly I need Vivaldi(chromium) to get my work done. I can't read most HAR files that chrome horks up. There are both new and long-running bugs in the dev tools as well. I haven't dropped it yet, but when I do, yet another company will have no one who cares about Firefox.

It doesn't seem to change anything other than marking current tab blue.

Mozilla have shown and time and time again that just when you think they surely can't make a bad change (and keep all the previous bad changes) for the Nth time in a row, they absolutely can.
