Is that official mozilla build or something else? I see that on Wayland builds only.

Hi,

Sorry Sylvestre([e-mail]).

Is that official mozilla build or something else? I see that on Wayland builds only:
From mozilla site(Official?):
Name 	Firefox
Version 	65.0a1
Build ID 	20181024100114

Downloaded from Mozilla Nightly Download page...

See the mirror of the folder:

Thanks.

I am able to confirm and consistently reproduce this issue with the following test environment:

• Firefox as distributed by CentOS package firefox-60.5.1-1.el7.centos.x86_64: Firefox Quantum version 60.5.1esr (64-bit).
• Running on CentOS 7.6.1810 with all latest updates as of March 13, 2019.

Navigate to https://slashdot.org in a new tab. I did not determine which element of the site was triggering the behavior. It might be from one of the ads that they embed.
