Extends private leaderboard capabilities of the adventofcode.com website by tracking the first time a user opens a day's challenge. Uses a backend to store the first-opened times for each user. Once you first visit a day's task, the browser extension sends this timestamp to the backend. It also scans your page visit history of AoC problems/days, so it works for past events as well. When you open a private leaderboard, NoRush queries first-opened times for all members from the backend and computes the scores based on that.
### Fixed - Support containerized use on Firefox - When using contextualIdentities, cookies are stored at multiple places - NOTE: If one of the stores has a stale session cookie, the extension will fail to load
