[Lug-nuts] Firefox crashes

I don't really get on the upgrade treadmill. I've been running Firefox 84 on Fedora 23 or something for awhile. Its in a VM I had a system issue with the host and had to do a reinstall and upgraded to fc 36. Everything was fine, running my fc 23 VM's on a fc 36 host. I'm on a different VM, my "fun" VM as I write this, which also runs Firefox 84 on fc 23 with no problems. I'll upgrage at some point. The VM with the issues is my "finance" VM. I use it for my credit cards and banking and all that. Banks started to complain about my Firefox 84, so I tried to upgrade to 113. It crashes. A lot. So, I built a new VM with fc 38. And installed Firefox 115. It crashes almost immediately. But I was able to get some forensics. Its complaining that it is sending a 64 bit code to a subsystem that "doesn't support it". Implying that there is a 32 bit library somewhere. I sort of do need to log in to banks and all that. Any thoughs or suggestions? It seems really unlikely that there would be a 32 bit library somewhere. Desktop browsers and Firefox are getting increasingly less mindshare. Is this just EOL thrashing? Any thoughts? As you may have guessed, the hardware is pretty old, but I don't see where that would be an issue with this. -Gary
