Hello!
When Firefox starts, it usually generates a lot of traffic. It contacts Mozilla Servers to check for updates, download new features, add-on servers to download and install new extensions, themes, and plugins, DNS servers on its own, SSL/TLS certificate authorities, gelocation services to determine the user’s location and provide location-based services and crash reporting services. If the Firefox traffic goes outside the VPN tunnel for any reason (check Firefox Internet connection configuration) it will be blocked by Network Lock and Firefox main window pop-up will be delayed severely.
Furthermore, a potential new issue is ongoing, which is typical in Fedora and many other distributions "transitioning to" nftables by maintaining iptables syntax backward compatibility with translations and all that jazz (yet another evidence of lack of adequate design skills and vision typical in some Linux environments).
libvirt adds rules via iptables-nft with xtables commands and nft can't process correctly anymore the ruleset. Eddie uses nft whenever it finds it, by default, so if you use libvirt for any purpose (from QEMU to VirtualBox and more), a big rule set mess can arise whenever a program runs nft. The issue has been at the moment tackled and resolved in the AirVPN Suite 2.0.0 beta 1 which goes back to launch iptables-nftables when available (even when nft is available) to avoid the mess.
On Eddie, please modify the "Preferences" > "Network Lock" > "Mode" combo box into iptables-legacy and the problem should be resolved.
This problem could be resoved by Eddie 2.24 beta, please test it: https://airvpn.org/forums/topic/57401-eddie-desktop-224-beta-released/
