Hi,

I haven't been able to reproduce this issue on Windows 7 using Firefox Nightly 65.0a1(2018-11-05), Firefox Beta 64.0b6(2018-11-01) or Firefox Release 63.0.1(2018-10-30).

Could you test if the issue is reproducible in safe mode, here is a link that can help you with that:

If the issue still occurs please try using a new profile, you can find the steps here:

Thank you for reporting!

Same behavior in safe mode and with new profile.

As I told before I tested it on a clean new PC.
We have this issue now on all PCs in the company.

I've installed FF 63.0.1 now in a Win7 VM without any additional antivirus or firwalls installed.
There was no FF previously installed.
Same issue.

Ok, I've now installed FF nightly 65.0a1 in the VM.
The issue doesn't exists there!
