I have the Firefox extension Vault Timeout set to On Browser Restart, and the timeout action is set to lock. This works as expected during the day (i.e. vault stays unlocked) but nearly every night, the vault locks for some reason overnight and I am asked to re-type my master password again most every morning when I start working again. I do not close the browser overnight, I just put my MacBook to sleep by closing the lid. Perhaps the Mac sleeping overnight somehow causes the Bitwarden extension to think the browser has restarted?
Bitwarden Extension version 1.50.0
