Hi desmond1, do you use a dark system theme? There is a setting to decouple page colors from your system theme, but you may also need set an override through the back door. Here are my thoughts:

(1) Set Firefox to always honor page colors by never overriding them

This article has the steps: Disable high contrast mode in Firefox

(2) Set Firefox to tell websites you prefer a light theme

(A) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

More info on about:config: Configuration Editor for Firefox. The moderators would like us to remind you that changes made through this back door aren't fully supported and aren't guaranteed to continue working in the future. Since I have tested this one frequently, I feel comfortable mentioning it.

(B) In the search box, type or paste ui.systemUsesDarkTheme

(C) Firefox should display a bar with some radio buttons to choose a new preference type, followed by a + button. Choose Number and click the + button:

(D) Edit the value to either 0 (prefer Light) or 1 (prefer Dark) and then click the blue check mark button or press Enter/Return to save the change.

You should noticed a change immediately on the about:config page.

If you only want to change Google and not all sites, how are you setting your preference on Google? Normally that would be stored either in your account (if you are logged in) or in a cookie (if you are logged out) or both. So one possibility is that you need to avoid clearing the cookies set by Google.

Hi desmond,

You can simply click the Settings menu from any of your Google search page and click on the "Dark theme: on" to disable it.

Kiki & jscher2000,

Thanks for the feed back. I do currently reset Google's Dark Theme everytime I use their browser. I will reset my options in Google.

My goal is to get rid of it everywhere. For someone with my aged vision, I have extreme difficulty reading the gray wording Microsoft and other websites use for explanations or hyperlinks. So, for me, black on white is far better than white and gray on black.

I am going forward with jscher2000's recommendation as far as I can take them.

God Bless Y'all for taking time to respond.
