A user shared that Firefox crashes for two users as soon as they access MS services like portal.office.com. As soon as they exclude the users from the SSO configuration, it works again. I think the issue is from the fact that [we neglect cases when `device_headers` is not present](https://searchfox.org/mozilla-central/rev/aecb006bbb135d707ca4b8cea7572dd8abab6817/netwerk/protocol/http/MicrosoftEntraSSOUtils.mm#105). I managed to reproduce this issue by manually popping the `device_headers` header from the SSO cookie (Based on the log, I noticed that the `device_headers` header isn't present in the cookie).
