    slow computer - ubuntu 21.04

    I have two computers on a kvm. Both are running with 21.04 One is slow and keeps on crashing (kinda - wait long enough and it seems to uncrash). I suspect that I have something, in the slow machine that is hogging stuff. Oh, I am also using firefox 9.0.1 When I say crash I mean to say that my mouse stops working and firefox is no longer accessable (except for current window). When I am in the Terminal and am doing a sudo command (like; "sudo apt update" it takes the slow machine up to 20 seconds to give me the name quiery, on the other machine its instantaneous. OH, when firefox freezes it eventually puts a box on the screen telling me it screwed up and wants to send the info to them and I have a choice to have it force a quit or wait. Neither works. it even gets better! If I goto the monitor and try to end it doesn't. if I try and kill - it doesn't. However, in the fullness of time, it will eventually either quit or give me the box telling me it has a problem. When I choose to Anyway, I also suspect there is some way I can tell what the bad thing causing this is. I have written several messages on the firefox forum - no replies.

    Hopefully there is some solution to my problem?

    Thank you...................

    Really Firefox 9.0.1; did you mean 90.1, ie, running the daily or a development version?

    The normal repos version of FF is 89.0.1 so if you are using 9, or 90, where did it come from?

    You are right! It IS 89.0.1! (dumb mistake - sorry) In the time I took me to get over here and send this my firefox told me it was sorry - it was frozen when I left to come here and send this! That means, that it was frozen for about 3 to 4 minutes all told. (sometimes its forever)

    Are these Virtual Machines (KVM/QEMU)?

    Or a hardware switch with Keyboard Video Mouse?

    Do you have this experience when you disable all Firefox extensions and close tabs?

    I would create a second firefox profile just for testing.

    Does another browser such s Brave show these symptoms?

    Have you tried to reverse the switches on your KVM hardware?

    Switch A to Machine A
    Switch A to Machine B

    Worth a few minutes to experiment?

    It behaves this way even when the other machine isn't even turned on. My kvm is for 4 systems (I use the others when I am messing with other computers) I doubt it would make any difference as switching them is just a matter of changing plugs and this started before I had even plugged in the other system. I figure if the other one is not even on and this is happening then where they are plugged in shouldn't make any difference. It happens, for instance, when I am not even using the kvm which I tested before I installed the current one. Oh, I just reconnected directly which was easier than switching the kvm connections as I have the three cables and just hooked them up directly.
    Same problems.

    I am convinced something is running and hogging. Just can't figure out what it might be.

    Lordy! Forgot about Logs! I now have it on my dock so I won't forget it. It hasn't blown up today, yet. I have faith, however...........
