Like I said, I will not change my theme.

And I also said I spent a fair amount of time googling for about:config changes, which, when altered, did not do anything useful.

Basically I wish to restore the appearance of the old firefox while avoiding downpatching, if possible.

Try this code in userChrome.css:

:host, :root {
color-scheme: light light !important;
}

This helps a little bit, thank you -- but it still wants to switch back and forth between light and dark mode when displaying a blank page during loading, and the little bar that appears at the bottom left when loading a website (or holding your cursor over a bookmark) is still dark as well. Can this be fixed as well please?

Edit colors as desired:

/* Directly set colors for mouseover status panel */
#statuspanel-label {
    color: #000 !important;
    background-color: #eee !important;
    border-color: #eee !important;
}

Thank you, this solved it. Is there a specific one for the blank page when you have an empty tab open? It switches between dark and light mode when loading pages and it's getting a bit annoying...

At this point, I don't know of one. You also could check on https://www.reddit.com/r/FirefoxCSS/

I do not have a reddit account, nor do I have any interest in making one. So I guess I will have to live with the crappy darkmode when loading pages. :(

Thanks for your help, regardless.

Well... the bookmark window is also in darkmode now, for some reason. How do I make it stop? Heh...

You can fix this by selecting a theme that has dark text on the tabs instead of light text.

You can change this pref on the about:config page from 3 to 2 to revert to the Firefox 94 behavior regarding to prefer dark or light background for webpages.

• layout.css.prefers-color-scheme.content-override [dark:0, light:1, system:2, browser:3]

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

Didn't work, unfortunately. And like I said in my original post, I don't want to replace my theme with one of Firefox's new crappy ones. Anything I can do in the userChrome.css file?

This is all a bunch of crap! Users should not have to do handstands and Mozilla/Firefox should not impose their preferences or interpret things that users DO NOT WANT!!!! Firefox/Mozilla should make it possible for users to determine what they prefer and one of those things should not be a forced change of theme in order to get back to where they can read their screens!!!!!

Couldn't have said it better myself.

Under the covers, Firefox checks your toolbar theme colors and sets the following preferences which seem to be the connection between your theme and the rest of the browser:

• browser.theme.content-theme
• browser.theme.toolbar-theme

If you watch the values as you switch among themes, other than "System", you'll see:

• 0 => dark
• 1 => light

The problem with manually changing those preferences is that every time you open a new window, Firefox updates them to match your toolbar theme. So there needs to be something new that users can set, preferably easily.

There is a proposal on file (possibly more than one) to add a control on the Settings page. However, UI changes take a while so I don't expect it by Firefox 97. For the near term, for the parts of the browser not covered by layout.css.prefers-color-scheme.content-override, you'll need to change your toolbar theme or use some other kind of workaround.

I don't even dare downloading the latest update for Firefox now. I fear they will eff me up even more.
