Ubuntu Firefox GP Web issue

[RovshanRajabli]

Dear Team,Does anyone have a problem with GP on Ubuntu 22.04 when using Firefox?
Detail: I have an issue when I try to access some websites via Firefox while using GP, Firefox cannot open any of the websites.
When I turn off GP, everything is fine.Need some advice.
GP version is 6.1, Firefox version is latest, pan-os version is 11.0.0

Did you ever find a resolution for this?  Chrome seems to be fine but Firefox can't open any sites.

Hi!

I find some workaround. I downgraded the agent version to 6.0.5-c12. Everything works fine on that version.

As I tested, 6.0.5-c12 is the most stable version for Firefox on Ubuntu 22.0.4

I think this could be a conflict with Snap applications.

I had the same issue on our Ubuntu 22.04 machines. Snap apps try to use the DNS settings exposed via the systemd-resolved API, however, GlobalProtect replaces the /etc/resolv.conf file provided by systemd-resolved which breaks this behaviour.

I found a workaround is to add the following content to /etc/systemd/resolved.conf then restart the systemd-resolved service.

[Resolve]
DNSStubListenerExtra = 127.0.0.1:53

I'm not sure who's in the wrong here. I suspect GlobalProtect because it overwrites the /etc/resolv.conf file in a strange way (sym-linking to its own config file.)

Anyway, I hope this helps for you.
