What URL is loaded in the tab when you do this?

Do you have e10s enabled?

Comment 2

[Mindaugas <LA-MJ>]

It seems only about: URLs are affected. e10s is enabled.

Comment 3

[Mindaugas <LA-MJ>]

This invalidates my assumption that it's a regression.

My aurora profile had e10s disabled. Enabling e10s leads to the same issue.
Conversely, disabling e10s on nightly prevents the problem

This sounds like bug 1204215 then.
