[Mozilla Enterprise] Problem rendering initial page firefox 68.1.0, 68.2.0 ESR RHEL7

[Benedict, Stew]

Hi,

We are working towards migrating to RHEL7 and a newer firefox for our POS systems.  We fine tune the browser ui and run the browser as a seperate unpriviledged user, presenting them with a local homepage.html, with limited choices that take them either to the graphical POS app or to the home office portal.  As part of this "lockdown", in the past we have hidden the urlbar to prevent the users from going to arbitrary sites.  In our current 52.6 and a 60.8 build I did before moving to 68.X, I was able to do this via chrome/userChrome.css:

/* Remove Page Actions Menu */
#page-action-buttons
{
    display: none !important;
}
/* Remove the UI "sandwich" button */
#PanelUI-menu-button
{
    display: none !important;
}
/* Remove the urlbar */
#urlbar
{
    display: none !important;
}
/* Remove Developer Button (added via customize) */
#developer-button
{
    display: none !important;
}

This still works to suppress the urlbar, and for home office/lab systems we have a mechanism to expose the urlbar and the developer tools icon for troubleshooting web pages.

If the urlbar is exposed, homepage.html loads fine. If it is hidden, the page loads, the tab title changes as expected, but the page does not render, it is just white. If I click on the print icon, the preview renders the page.

If I open a new tab and click on "home", which loads the same page, that tab renders fine.

It doesn't seem to matter if I use homepage.html, or launch firefox with another url as the startup page (say www.google.com<http://www.google.com>), that intial page still does not render.

Any thoughts? Is there a better way to hide the urlbar?

Thanks
