I had a Fold4 and now have an s25 Ultra and had none of those issues with Firefox either. Works just fine for me and I even have some extensions I’ve put on that aren’t technically supposed to work in the mobile browser so I was fully expecting some jank. But still works fine.
There’s ads over the PA? I have never heard any. It might be because I’m typically in-and-out and focused on just getting what I need or maybe I’ve just been tuning them out. I’ll have to listen more carefully next time I’m at Target and Walmart.
