There are two problems here:
1) The presence of defaults/pref/autoconfig.js is triggering the reboot flag. It shouldn't do that, the file should just be left alone.
2) The uninstall survey checkbox is interfering with the radio button that allows opting out of the reboot and causing that button to not be shown.

The second problem is the more pressing one because autoconfig.js isn't commonly found on user machines, so I'll work on it here and probably file a second bug for the part that's specific to autoconfig.js.

This is a regression and a P1, is it worth uplifting it to the Beta branch with the Fx63 RC build happening on Monday?

Bug 1497907 - Don't accidentally hide the uninstaller reboot opt-out radio button. r=agashlin

[Beta/Release Uplift Approval Request]

Feature/Bug causing the regression: Bug 1448804

User impact if declined: Users are not able to opt out of rebooting at the end of the uninstaller if a reboot is needed to finish the process.

Is this code covered by automated tests?: No

Has the fix been verified in Nightly?: Yes

Needs manual test from QE?: Yes

If yes, steps to reproduce: See comment 0. This patch doesn't cause the reboot prompt to not appear at all for those STR (that's bug 1498044), it just enables opting out of it.

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 tiny (and, really, cosmetic) patch to code that only runs after the end of the uninstall procedure.

String changes made/needed:

I verified the fix using the latest Nightly 65.a1 on Windows 10 and the bug is fixed partially. It doesn't ask me to reboot after I uninstall Nightly, but it does ask me for a restart when I try to install another Firefox version. 

And when I used beta 64.0b4 I still got the prompt with the reboot option in it, https://imgur.com/a/cMQ5qhC.

I think that's expected because bug 1498044 is still not fixed; I filed it separately from this bug because that part of the fix is not as high of a priority.
I verified the fix using the stub installer for beta 64.0b6 and .exe file for Nightly 65.0a1 on Windows 10 x64 and Windows 7x64. The issue is not reproducing anymore, except the one I mentioned in comment 10, but that one I will track in bug 1498044.
