Screenshot from 2019-06-03 21-33-23.png

Steps to reproduce

1. Delete ~/.mozilla/firefox
2. Download build 20190603160429 (not sure it matters if it is after 67, but 
this is what I used). Add policies.json file to disable updates.
3. Start Firefox
4. Notice profile is "default-release"
5. Create new profile using about:profiles UI, call it "whatever"
6. Quit Firefox
7. Start Firefox
8. Notice profile in use is "whatever", not "default-release" This is Bug 
1556603
9. Quit Firefox
10. start Firefox with --safe-mode, start in safe mode
11. Quit Firefox
12. Launch Firefox

What happens:

Error message saying "You've launched an older version of Firefox"

Expected result:

No error message, Firefox launches into a profile.

Users will be blocked from using their profile if they ever use safe-
mode.

Ok, there are a few bugs that combine to cause this behaviour. I have
fixes for all of them and while I'm sure of being able to get them into
betas I'm less sure of getting them into the next release. So I'm going
to attach the simplest fix here that should be perfectly safe to uplift.

Bug 1556612: Hardcode considering this an upgrade if the last build to run was 
run in safe mode. r=froydnj

When safe mode runs it writes out "Safe Mode" as the compatibility version (bug
1556831). Due to bug 1556832 and bug 1556829 this makes us think that the next
run is a downgrade.

This is the simplest possible fix that should be totally safe to upload to
release.

Pascal, I figure this should be in the next dot release; marking it as a

Dave, does this bug only manifests with a policies.json file to block
updates? In that case that sounds like it would affect a tiny % of our
users and could be included in a future dot release but would not
trigger a 67.0.2 ASAP. If you think this is a widespread problem, should
we stop  updating users to 67.0.1? Thanks

This bug affects anyone who uses safe mode.

well, I just launched 67.0.1 in safe mode and it works for me…

[EDIT] I can reproduce the bug on linux on the second start in safe mode

Could you request an uplift to release? Thanks

### Beta/Release Uplift Approval Request
* **User impact if declined**: After running Firefox in safe mode the next 
launch of Firefox will tell their user that they have downgraded firefox and 
without some manual steps the user will be unable to use their profile ever 
again.
* **Is this code covered by automated tests?**: Yes
* **Has the fix been verified in Nightly?**: No
* **Needs manual test from QE?**: Yes
* **If yes, steps to reproduce**: Automated tests cover the code changed but 
since there are not good full startup tests it would be worth QE verifying this 
quickly. The steps are:

1. From about:support restart into safe mode.
2. Quit and launch Firefox.

Firefox should open without displaying the downgrade dialog.
* **List of other uplifts needed**: None
* **Risk to taking this patch**: Low
* **Why is the change risky/not risky? (and alternatives if risky)**: This is a 
minimal change targetted at the specific situation here, there is no risk of it 
impacting anything else.
* **String changes made/needed**: None

Hi,
       i've been able to reproduce the bug on Mac Os 10.13 (even on the latest 
nightly) on my side but not on Windows10 nor on nightly or release (67.01) 
using a computer with lots of profiles and also a clean one that never had 
firefox before.

Regards
David

Let's get this onto m-r so we can start a build for 67.0.2 soon (though
we are still going to work on verifying)

Reproduced the initial issue using 67.0.1 on macOS 10.13 and Ubuntu 18.04 
64bit. Verified that the issue is fixed on 67.0.2 across platforms (macOS 
10.13, Ubuntu 18.04 and Windows 10 64bit). 
I also did some exploratory testing around it to search for potential 
regressions that might have surfaced but could not find any.
