Lichess and Firefox Multi Account Containers

Most Lila features outside of puzzles and play with computer require interaction between multiple users. Anything that facilitates switching between them is useful for developers.

Use Firefox's Multi-Account Container extension to have multiple active users logged in to a lila instance, all in their own tabs with their own session environments (cookies, local storage, etc), without using private browsing. More importantly, if you set up a few containers dedicated to specific users, you'll never have to log that user in again. Just select the user/container from the menu and let Firefox/cookie/lila handle the rest in a newly created tab.

This sample Multi-Account Container menu associates containers with spamdb users. The sessions in each container persist across tab closure and browser restarts - just like your default session:

To make the tabs reflect the username, go to the st.headTitle block in the head tag of the apply method in app/views/base/layout.scala and make it look like this:

          st.headTitle:
            if ctx.blind then "lichess"
            else if netConfig.isProd then fullTitle | s"$title • lichess.org"
            else ctx.me.so(_.username) // schlawg is a dirty, filthy boy

Don't check that in by mistake.

To further distinguish them, you can use spamdb.py --user-bg 400 option to create users with a random background image selected from data/image-links.txt
