I use a dark background theme to reduce glare. Text usually appears white, as expected. Today, 12/13/24, the text is black. I am using version 133.0.3 (64-bit) Firefox Browser. I downloaded an update within the past few days, and while I have used the browser, I haven't typed anything onto a browser page until this morning. Text and background appear normal with other applications. I was wondering whether this has been reported or found previously. I am continuing my search for other applications this my affect.
