Saw a weird issue on nightly where after starting a profile in safe mode, I was unable to re-launch the same profile in normal mode. Decided to investigate and found a more serious issue.
Summary: Upgrading to 67 from 66 starts a completely new profile, even when using a single profile that has never been used on another release channel.
Steps to reproduce:
- Delete contents of ~/.mozilla/firefox
- Download Firefox 66.0.5, add policies.json file to prevent accidental upgrade
- Launch Firefox 66
- Add uBlock Origin to profile to ensure I can easily see the difference between this profile and a new one.
- Close Firefox
- Download Firefox 67
- Launch Firefox 67
Firefox says that it created a new profile.
Firefox uses the profile created in step 3 above.

Contents of profiles.ini in 67
