Some of the text is black on the deals page.
The text is there and you can read it if you highlight it.
Maybe something got broken when it was reverted back from the R U OK? theme?
I'm using Firefox 104.0.2 (64-bit). It seems OK in Chrome.
Edit: I suspect it's me. It looks OK when I open it in an incognito window in both light and dark mode. I've disabled almost all of my add-ons and themes, but it still looks weird.
Edit again: It's definitely caused by the Facebook Container v2.3.3 add-on. Updating to v2.3.4 solves the problem.
Works fine for me in 104.0.2. What other add ons are you using?
