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.

For a dev instance with spamdb generated users, this sample Multi-Account Container menu maps containers to user sessions which 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) "lichess"
            else if (netConfig.isProd) fullTitle | s"$title • lichess.org"
            else ctx.me ?? {_.username} // schlawg is a dirty, filthy boy
          },

Don't check that in by mistake.

You could instead make spamdb users with command line option -bg 400 to give each one a random background image (which can make it easier to distinguish them). If you don't like the generated uids, they can be customized in lila-db-seed/spamdb/data/uids.txt. Background images are chosen from lila-db-seed/spamdb/data/image_links.txt.

For example:

python3 spamdb/spamdb.py --drop all -bg 400 -u 32

Creates a default database with 32 normal users selected from the first 32 lines of uids.txt (in addition to the special users - lichess, shusher, etc)
