For comparison, Chrome updates "every two-three weeks for minor releases, and every six weeks for major releases".

I guess Beta is moving to daily releases? I suppose it's good, generally I have to restart Firefox once a day for resource leaks and restarting through the update UI is easier than opening the browser console.

I was using Nightly for a while but it turns out that even daily updates aren't fast enough for that. If a new patch breaks something, typically the offending patch isn't backed out and it takes 6-12 hours to get fixed, meaning the fix isn't available in the next nightly and you have to suffer for several days.
