I see browser freeze when the popup is opened/closed repeatedly. Filed as Bug 1734368.

The patch landed in nightly and beta is affected.
:stransky, is this bug important enough to require an uplift?
If not please set status_beta to wontfix.

Comes with regressions (mostly caused by Gtk backend) so better to keep in nightly.
