[SOLVED] Bug Web-GUI Firefox+IPv6

[Maksel]

Hello. I have access to web management via IPv6 + Firefox.
All work well.
But after some update the firefox - broke. Long ago.

There are no problems with Google Chrome. There is an error on the screen.

Are you sure that your Firefox settings are correct? It seems strange to me, that it works in Chrome but not in Firefox

I have several setups. 1 - cluster, 2 - separate proxmox, without cluster.
On all servers - Firefox +IPv6 the web is not displayed correctly.

Win 7 + Firefox 86.0.1 (64-bit) - bug
Win 2016 + Firefox 86.0.1 (64-bit) bug
Ubuntu 18.04.5 + Firefoh 86.0 - bug

Win 10:
I uninstalled the newer version of Firefox 86 and installed the old one, Firefox 82 - no errors.


Coogle Chrome 89.0.4389.90 - no errors.

PS. ProxmoxBackupServe - Firefox 86.0.1 + IPv6 - also displayed incorrectly. Chrome 89.0.4389.90 - no errors.

And you haven't changed any Firefox settings before and after the installations?

Hi. Not. I have not changed any settings. Here I installed a new Windows 7 + download last firefox.
I did not change any settings.
Can't you check with yourself, or we do not have an ipv6 address on your hosts.

Used to work on old version of firefox, then firefox was updated and stopped. (I don’t remember the version for which last time I worke

We also found out. If you add an entry to the hosts
2a.......:20 prox20.test.net
and open in firefox by this domain name https://prox20.test.net:8006 data is displayed.
it does not work if it is enter to the address in the ipv6 format https://[xxxxx]:8006

The question can be closed. Firefox upgraded to version 87.0 - and no problem.
