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.
