This just started happening to me today (2-3 hrs ago), 3-14-26, but the interesting part is that earlier today everything was normal.
I’ve been using Adblock Browser for the longest time and never had any issues. So, to fix the problem I installed Chrome and Opera, but the problem persisted. I then installed Firefox and the problem went away, but I preferred the font I was used to on Adblock and Firefox just didn’t look like what I wanted.
So, to get to the point I reinstalled Samsung Internet and everything seems to be back to normal.
I have no idea why it’s back to normal with Samsung Internet.
My Android Motorola still has gerbil font. It’s so annoying.
