LaunchBrowser failing to run with error "need to run as root or suid"

[ptgolden]

I am trying to open a Web browser upon launching redbean with the command LaunchBrowser("/"). The server starts up fine, but the browser fails to open with the error message need to run as root or suid.

This is Ubuntu 22.04. My default browser is Firefox Beta installed via snap. Below is the output of ./redbean.com -vvv

$ ./redbean.com -vvv

It may be worth noting that running the command "/usr/bin/xdg-open" http://127.0.0.1:8080/ does work if I run it in my shell.

This code in .init.lua fails with the same message:

unix = require 'unix'
unix.execve('/snap/bin/firefox', {'/snap/bin/firefox', '--version'}, {})
unix.exit(1)

$ ./redbean.com 
need to run as root or suid

However, calling a non-snap version of Firefox works fine:

unix = require 'unix'
unix.execve('/home/ptgolden/Code/tools/firefox/firefox', {'/home/ptgolden/Code/tools/firefox/firefox', '--version'}, {})
unix.exit(1)

$ ./redbean.com 
Mozilla Firefox 97.0.1

This is certainly an issue with snaps, not with redbean. Unfortunately, the default method of installing Firefox and Chromium on Ubuntu is now snaps.
