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
