Complete shut down. Only happens in FF and twice in one day. I think its a FF memory management issue because both times I had >15 tabs open.
There is something going on here. I'll run up to 15 or so tabs open and I've never had an issue (some JS demands excess CPU, but memory is fine)
On the install disk, before you go to sleep, start memtest86+ and let it run. It also sounds like you are running into a bad-memory issue. When that occurs -- "is like a box of chocolates", but when you it the bad address, the system will crash - and it may bring the entire system down. With memory address radomization in the Linux virtual memory manager -- there is no telling when, or if, any one program will have access to the bad RAM.
Firefox, in requesting (and in using in some cases) gigabytes of memory -- is one of the more likely apps to hit the bad address....
Another issue could be swap on an SSD. We use them because they are fast. But SSDs have limited write cycles, they get burned out after so many writes. You could be hitting some burned out sectors on the Swap.
I do not think its new enough to be an ssd. for all the writes I do downloading things I would never want an SSD except for backup since they are glorified flash drives.
Say what you will about SSD, but from personal experience they're okay. I've been using them for system disks, including swap, in servers and desktops since approximately 2006 without issue. At any given time I've got about 30 hosts up and running, most with SSD installed. If I remember correctly, I did have one fail, but that's still a good record. I've seen spinners fail at a much greater rate. Indeed, the first desktop I tried them in in 2006 is still up and running.
I also use swap configured just a bit bigger than the installed RAM, except on servers with 512-GB of RAM. Back in the SunOS days the rule-of-thumb was to configure swap to be three-times larger than your RAM, but that was then!
YMMV of course, but for me SSDs are okay.
What Brand??
Mostly they are much more expensive than normal drives and I do not have a color printer..
For the most part, whatever is available. Probably mostly Intel, second would be Samsung. Yes, they're more expensive, which is why I use them mostly for the root partition. Spinners are mostly used for /home. As such, 256-GB is more than big enough for most root partitions. My home desktop has one 1-TB nvme drive, and two Seagate spinners, 10 and 16 TB. At work I've got one server with two 1-T nvme's configured as a RAID-0 stripe, with 658-TB of RAID-6 Seagate spinners. smartctl reports about 30,000 power-on hours with no errors and 100% of spare sectors available on the nvme's.
