Hello,
I'm using Fedora 31 with
google-chrome-stable-86.0.4240.111-1.x86_64
firefox-82.0-4.fc31.x86_64

Engine was deployed from a CentOS Linux 8.2 host and then with hosted engine wizard, using the appliance rpm (Package ovirt-engine-appliance.x86_64 4.4-20200916125954.1.el8)
Connecting to the same 4.4.2 engine I get:

1) different landing page graphics
firefox:

chrome:

2) corruption in several editing pages in firefox, where a sort of top white part seems to compromise the lower part of the window, making impossible to complete.
eg in new network I don't see the lower part related to MTU...:

3) in Stotrage --> volumes page if I click on a volume, firefox shows no problem, but chrome gives a gui exception:
