Firefox for iOS

I tried looking up a few things in the FAQ for (Firefox for IOS,)… updates… but unfortunately, it WILL NOT SHOW ME any of those articles (I think it showing that there are 4 articles there to read). But when I click them, nothing. Is it being blocked or how do I read them? I feel an idiot when I use ANY of my phones! The below image is supposed to be a page to help me change my email for “Cash App”. It’s saying I can’t use my: “[email removed]@myyahoo.com” email address. Firefox uses Google to search & then it asks me, do you want to open this in Firefox… I have been using an Android & it comes up as 2 separate phones. (One for when I use Samsung Internet & one for when I’m using chrome/google..?????) I don’t know what’s going on, but someone is either hacking my emails through Google or through my phone #. My Google maps doesn’t even go on the roads I walk or drive on. It shows be cutting across fields & driving over or through buildings. Not just when I’m in my car, but anywhere I go & with whomever.
