1960897 - firefox does not detect network change

Status: RESOLVED INVALID

(Core :: Networking, defect)

Description

[Amin Vakil]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:137.0) Gecko/20100101 Firefox/137.0

Steps to reproduce:

Connect to a VPN which creates a network adapter or disconnect from one.

Actual results:

Firefox gets disconnected. I've checked using wireshark and it's using previous IP in new interface.
For example my wifi IP is 192.168.1.2/24 and my VPN local IP is 10.0.0.2/24, when I connect VPN, it uses 192.168.1.2/24 in vpn network interface.
It does not get fixed until a complete restart.
It happens the same when disconnecting, it uses 10.0.0.2/24 in wifi interface which does not work.

Expected results:

Use correct IP address in each interface.

I cannot remember definite, but this is happening since a couple last releases since two months ago, around that time.

Sorry for the noise, this is somehow related to firejail and it works fine when it's running without it.

Sorry again.
