Firefox starting automatic on each login?

Start understanding how to configure i3:

To disable autostarting firefox with this readme edit ~/.config/i3/config and comment out this line:

#exec --no-startup-id firefox https://github.com/endeavouros-team/endeavouros-i3wm-setup/blob/main/README.md

~/.config/i3/config is the main configuration file for i3, get into this file and configure i3 as you like, all settings have comments to give you information about the following setting. https://raw.githubusercontent.com/endeavouros-team/endeavouros-i3wm-setup/main/.config/i3/config

No transparency?

enable picom in ~/.config/i3/config by uncommenting this line:

#transparency 
exec --no-startup-id picom -CGb

And in some cases you will need to use a different configuration ( Nvidia GPU/Driver p.e. but also others) Do some research will help you or ask at the chat or forum.
