Firefox has started crashing regularly

Win 10.0.19045 , Firefox 131.0. For the last week or so Firefox has crashed out several times a day. What has changed to make this happen, and how can it be prevented?

I have the same issue with Windows 11 Pro, Version 23H2. Firefox 130.0.1 crashed occasionally, but 131 crashes all the time. Most restarts restore the session, but not all. My master password for my password manager (bitwarden) has to be re-entered each time.
