1465153 - Cannot set FF release as default e-mail program on Win 10, always takes FF Nightly.exe instead.

Status: RESOLVED DUPLICATE of bug 675428

(Firefox :: Shell Integration, defect, P2)

Description

[Dan]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Build ID: 20180516032328

Steps to reproduce:

on Win 10 1803 (I call it April"-fools" update for several reasons), it is impossible to set FF release version as standard internet browser when the user has also installed Firefox Nightly.


Actual results:

Firefox Nightly the only choice coming up in "list of browsers" in the Windows 10 setting.


Expected results:

Should've listed all my different installed Firefox exe files.

I'd guess component: general ?

https://bugzilla.mozilla.org/describecomponents.cgi?product=Firefox
"Shell Integration
This component is responsible for determining if Firefox is the default browser, setting Firefox as the default browser, and setting the desktop background."

Actually it DOES open FF release when FF release is already running... that is the weird (but in this case GOOD) thing...

Is this still an issue with the latest Firefox versions?

Comment 5

[Dan]

as browser, working fine now, but under "default e-mail program" it seems that still only Nightly can be selected, neither Beta nor Firefox release versions.

Comment 6

[Dan]

Still an issue on Win 10 Home x64 1809 (also on 1903? Can anyone on 1903 test?)

It looks like I can select Firefox release in both default browser & email on my windows VM.

[Dan]

on Windows 1809?

Comment 9

[Dan]

Which Firefox browser versions do you have installed on your windows VM?

Comment 10

[Mark Banner (:standard8)]

Looks like it was 1903. I have Firefox release & nightly installed. I'm guessing this is probably something around registry settings or some form of registration.

Unfortunately I don't know the details of Windows to be able to help further here.

Fortunately I DO know what you can do next, to test the issue. Please also install Beta and Developer edition, then restart your PC and then check which FF builds appear in the "email client" list, am curious what results you will get. You may have to select different builds in that list to trigger the bug, not sure. Hope you can test this soon.

Maybe only 1809 is affected.

Sorry, I don't have time for this at the moment. Maybe one of our QA folks can help.

I can reproduce the issue on a test machine Windows 10 Pro (winver 1809). While the test machine is also affected by a similar bug to 1391080 (cannot find the right bug to link atm), the issue is even more visible: left contains the options for Default Email with only Nightly listed, while right shows the options for the default browser.

Also tested on a Windows 10 Pro (winver 1903) and the results were somehow confusing, although not sure if it's a regression at this point: the default email listed no Firefox, while the default browser listed many icons==versions of Firefox. Installing 70 release or 71 beta did not change the list of default email apps.

For both of the above Windows versions, the windows default listing contains a mix of : uninstalled versions, deleted versions, installed and active versions: no clue as to how to properly debug this and previous inquiry on cleaning that default browser list grew arms and legs with no solution.

I did not test on a clean environment, since I didn't have one at the ready and from what I remember from previous experiences with the Windows defaults it was tricky to irrelevant to use a VM for this particular kind of issues.
