LXC container - Firefox won't load any website. But other browsers ok.

[timonoj]

Hi all!

So I'm a bit confused with this issue I'm finding for the first time... I installed an ubuntu 24.04 template, then LXDE with firefox on it (the .deb version from the mozilla repo, which I manually added). Firefox won't load any website, including internal IP addresses. It fails immediately, doesn't even wait for a timeout.
Apt works correctly and I can download/install packages no problem. So I installed ungoogled Chromium. Chromium works just fine. I'm not sure what I'm doing wrong? Any ideas?

This is my ip a:

$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host noprefixroute  
       valid_lft forever preferred_lft forever
2: eth0@if113: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether bc:24:11:c4:3c:7e brd ff:ff:ff:ff:ff:ff link-netnsid 0
    inet 192.168.1.182/24 brd 192.168.1.255 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::be24:11ff:fec4:3c7e/64 scope link  
       valid_lft forever preferred_lft forever

Thanks!
