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.
