Firefox Multi-Account

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)

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
