I am experiencing system lockups when using firefox and chromium browsers. When the system freezes I can only recover by rebooting and reloading the browsers

How can I fix this problem?

Is there any way to escape the lockup other than rebooting?

    You should share more information about
      your hardware and OS setup in general.
      Package "inxi" will provide sufficient information.
        $ sudo inxi -A --basic -ms -xxx --filter-all
      
      Another useful tool which helps with diagnostics is "journalctl".
      With it you can see the logs from previous boot after driver crash
      or reboot:
        $ journalctl --dmesg -b -1
        $ journalctl --dmesg -b -2
        $ journalctl --dmesg -b -3
      
      Symptoms you describe could stem from faulty hardware (i.e.
      overheating, faulty components, failed solder joints, etc),
      resource starvation (low memory system and no swap), or bugs in
      kernel module.
      I've had somewhat similar symptoms on my system running stable
      (6.1) kernel on modern hardware and the situation was
      significantly improved after upgrading to kernel (6.12) and
      firmware packages from backports.
      Also try to disable video hardware acceleration in browsers, just
      to test if that helps with the issue, you can always turn it back
      on.
    
    There is a way to escape reboot if video driver had a crash and
    frozen the window manager, but the system is still running. 
    I've done it by using a script which would reinsert video driver
    module into the kernel if there is a specific message appeared in
    syslog.
    However this process will restart the window manager to logon
    screen, effectively closing previous session.
