Browser Wars - This Morning?

My 2012 Mac Pro is OS blocked at Mojave (10.14.6) and until this morning, Safari ((14.1.2 (14611.3.10.1.7)), has been fine with TMF, but now I’m getting a message:

" Unfortunately, your browser is unsupported. Please switch to a supported browser to view rich content, log in and reply."

What’s up with this? While I have Firefox, Safari has always been solid, working with all our financial sites, so there’s not been a need to change… And Safari is/has been my default for decades…

I’m still using a MBPro 2013 running <Mac OS Big Sur 11.7.3 works on that one. Shouldn’t be that much difference with your slightly earlier one???

Right, one version earlier, forced me to use Firefox earlier to see the Categories, etc… Strrange, as I was on late last night with no warnings… The 2012, ska ‘Cheese Grater’ with patches could be forced later, but I don’t want to deal with all the mysteries it may cause… So Mojave it is, until I have to invest in new hardware… Bad timing at the moment…

Just back from SF…
