Having switched to Zen Browser, something I miss with Firefox was its stability. I find myself looking up Zen browser bugs and workarounds too much. This is the 2nd or 3rd time I’m downgrading Zen versions due to a bug in the stable version, I never had to do so during my years on Firefox. Devs on Github making an app on their free time have can’t spend as long on QA as a multi-mullion dollar organization.
They haven’t released a stable yet and are clearly labelled as beta releases. Maybe there’s a hint why it’s unstable.
