It seems development was discontinued and the repo is now archived.
Second this! I find Jerboa still not quite there, and stick with the reliable and honestly pretty neat web app. Since it's a PWA, you can "install" it like a regular app.
Always learning ;)
Hopefully reddit won't take it down
Despite it not being available through i.reddit.com, compact mode is still reachable at reddit.com/.i, and I find it even better than old reddit for mobile.
Besides the typical privacy-oriented Firefox extensions, I love Sidebery. It's by far the best tree-style tab add-on I've ever seen. Beautiful and powerful.
