Firefox Dark Mode

[ImDrRichard]

Hello Everyone -

Wishing you all a happy, healthy, and better 2022!

I'm running Monterey v. 12.0.1

Woke up this morning and Firefox was in Dark Mode. Managed to change the theme back to my previous one BUT, for some web pages I go to, they now have a black background instead of white (Mac-Forums is NOT in Dark Mode, FYI).

I've looked all over for settings for Tabs, etc., but have found nothing.

The usual excellent help would be greatly appreciated, and thanks to all who respond.

Reboot?

 

[ImDrRichard]

Tried that. Still there.

Can you give some examples of sites where you expect them to be in "light" mode but are in dark mode? How do these sites look in other browsers?

Is your macOS using Dark mode?

 

[ImDrRichard]

No. Just looked at General in System Preferences. It is not.

Sure. YouTube, Google, Firefox Settings, All drop-down menus in Firefox from my "Favorites" Bar, etc.

Hmmm. Do you use Dark Mode as your system preference? I'm experiencing the same as you are (I don't normally use Firefox). I have Dark Mode set as my system appearance, and in Firefox, I get Google showing in Dark Mode no matter what mode I have set for the System. In Firefox' Colors option, if I set it to use system colors, Google remains dark no matter what, but the Settings page will switch from dark to light to match the system.

Here's what appears to work. In Firefox's Colors preferences, there's a dropdown box for Override the colors specified... Change that from Never to Always.

I believe I have found the answer:

I recently updated Firefox to v. 96.0.1 and the "dark" menus seem to be part of this new upgrade. I dunno why.

I've updated to Firefox 96.0.1 too, but in light mode there are no black menus. It switches to light menus.

Toggle light and dark mode in System Preferences > General and see the difference.

Hi Rich,
Well, you forced me to download FF

In FF preferences, click on "Themes". The following are offered:

System Theme Auto
Dark
FF Alpenglow
Light

In my not very extensive "playing around", I found the following.

The System Theme Auto changes the background more or less the way you describe.

Dark means what it says.
FF Alpenglow might appeal to some.

And LIGHT is indeed Light all the time.

Okay; as a scientific study, it is meaningless, but I think you might try the Light Theme and see if it suits you?

There's something very weird going on with Firefox. So I have two Macs: a 2019 Intel iMac and a 2020 M1 MacBook Air. Both on Monterey 12.1 in Dark Mode and Firefox at 96.0.1. I don't use it much, but I'm finding two odd things. On my MBA, it won't load anything unless I disable AdGuard for Mac. It says a secure connection failed. I don't have this problem on my iMac, and I don't know why. I'm going to have to dig into my AdGuard settings, but this shouldn't be so browser-specific (EDIT: that much is solved... AdGuard can filter by app, so I turned it off for Firefox... running AG beta on my MBA, so that appears to be the issue for whatever reason). Safari and Brave are fine. But here's the more relevant thing: on my MBA, Google loads up in Dark Mode. On my iMac, it's light. Same theme in Firefox (System Theme - auto) set on both. On the iMac, if I re-select that System Theme Auto option, Google will load dark. Just by re-clicking on it, even though it was already enabled and selected. If I quit and relaunch Firefox, Google loads light again, even though the theme didn't change. All this though ONLY on my iMac.

It's incredible LIAB; just as you say. Have you tried the Light Theme on FF to see if that helps because "Auto" can mean a lot of things and your idea of Auto may be quite different from FF's

Waiting to see if Rich (the OP) gets a different appearance on Light as well.

It's not what my idea of "Auto" is... apparently it is Firefox' and Google's idea. The settings are identical on both Macs (System and in FF), yet the experience is different.

EDIT: selecting the Light theme does make everything "light"... too light. It's not just the web pages that go light, but the window borders and everything. Normally, with a Dark system theme, Google's page still renders light, even in Safari and Brave. The big mystery here is why is Google's page rendering dark "sometimes" with the theme set to auto. Auto should be thought of as 'theme-less".

2nd EDIT: I forgot the OP said he wasn't using Dark Mode as a system preference. If I switch to Light Mode, FF and Google do render light when the FF theme is set to Auto. So even though there is "a" problem if Dark Mode is used as the system appearance on my MBA, if he really isn't using it, I don't know what to make of this. I think something is being overlooked.

Once again Ian comes to the rescue! Thanks very much Ian!

I have been using the FF theme "Blue" for a long time. During the last revision FF likely decided to make the menus dark.

I need a little color on my screen for tool bars, etc. so I'm going with Alpenglow for now.

Regards to all -

Best,

Rich
