"Open previous windows and tabs" does not work while using profiles

Hello,

I am experiencing an issue with Firefox Nightly when using multiple profiles.

On each of my profiles, I have enabled the option “Open previous windows and tabs.” On my main profile, the tabs and windows reopen normally when I relaunch Firefox. However, on all my other profiles, no tabs or windows are saved or reopened when I relaunch Firefox. I have verified that the option is indeed enabled for each profile.

Excuse me if this is a configuration error on my part; can anyone explain how to resolve this behavior in that case?

If this is a known and documented bug, I apologize for not finding it during my research.

Thx.

Referencing this post saving previous state (open tabs/windows) is broke... - Mozilla Connect
on mozilla connect.

Could be the same issue.
