Over the past two years it seems, both Firefox and Thunderbird constantly show "NOT RESPONDING" plus "FORCE QUIT or WAIT" while using the browser and the email. There never seems to be any reason for these messages coming up. In some cases the computer automatically switches from Firefox to Thunderbird while in the middle of performing operations on webpages (not always the same pages). Using Ubuntu 24.04 having updated from 22.04.
