Again sent earlier. Thanks for the intervening comments about vulnerabiliteis and versions. A lot of issues and suggestions have been made and raised. My brief response is that yes, according to nmap and my intention I had port 23, for ssh (I moved it) and port 5900 open and the rpc port, I think. I'm going by memory. Theoretically the only pinhole in the ISP router firewall was port 23. To use port 5900, you had to use an ssh tunnel. My web server is on another machine. Since I only use it for development, I don't leave it up. My actual web pages are hosted externally on a vendor's box. My experience with the upgrade treadmill is that it is a waste of time. By its own admission (if a concept can have that) the new versions will have issues and you need to upgrade. If the issues with an older version don't affect you, then it is perfectly fine to use it. Why upgrade and risk the fact that the new issues will affect your use case. The developers for Fedora 13 were no smarter or dumber than the developers who are writing Fedora 36. Or pick your distro of choice. The issue with an older release is that nifty new things come out and you can't really use them. But, if you run a VM with a recent version of the distro, you can use them just fine. The other issues is that if you are getting vendor support, they can only reasonably commit to supporting a limited number of versions. This is AMD hardware from '06. -Gary On Fri, Aug 05, 2022 at 06:19:54PM -0700, Rick Moen wrote: > Quoting Brian E.

The only thing I found in settings was tracking. I changed it to custom and unchecked everything. It always fails at the login screen. Either before or after I enter my credentials. Other pages work fine. Anyone using Firefox? On Tue, Jul 25, 2023 at 01:01:04PM -0600, Linus Sphinx wrote: > Upgrade to a 64 bit virus. Anything in F12/errors?

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
