Any Firefox users having massive problems w/v.152.0.1 (latest LTS) on older OSX ?

5. Unfortunately not. Safari cannot access this bank page, for whatever reason. (It's a very old version of Safari)

I'm using an older iMac with an updated OpenCore patch just to run a later version of OSX 10.15 -- "Catalina" (I'm so sick of these stupid names, which I can never keep straight).

I tried to find a Vivaldi download, which I've run on old iMacs before, but Vivaldi's Web page only list newer Mac installs. Windows versions are available back to v.1, but their "old versions" page doesn't include anything but Windows.

Thanks for mentioning waterfox. I was remembering things like seamonkey and iceweasel were out there, but hadn't seen them mentioned in a long time so I suspected they were no longer supported.

I tried to install Linux on this drive, but most of the partitions are formatted for AFPS, which Linux can't open, and the Linux partition disappears when I boot in OSX, so data transfer is a problem. When I'm satisfied my OSX backup is safe I'm planning to reformat all the APFS partitions -- if I can't run this version of OSX from an older format partition I'll just install Linux and forget that it was ever a Mac.
