Finally decided to give FireFox a try, but I encountered big problem: when trying to access local web server (I am software developer) running simply on port 80, firefox just pretend it's connecting, timing out after a while. Every other browser has no problem connecting, even scripts from console can connect without any problem. Tried every possible address: http://localhost/ http://127.0.0.1/ http://[::1]/. Nothing works, same result every time.

Also tried changing those settings in config: network.dns.disableIPv6, network.dns.disablePrefetch but no change.

Using Windows 11 22H2, Firefox 115.0.2, webserver is running in WSL2 and can be accessed by any other browser or application.
