I've been looking for something "official" from the Librewolf team regarding running Librewolf in Docker, but I haven't found much. There are a few initiatives that seem to support Librewolf Docker containers (eg Github, Docker Hub), but they don't seem to be referenced much nor heavily used. However, maybe the reason I don't see it much is that there are better ways to achieve what I'm looking for.
Better separation from daily OS environment and regular browsing environment
Ability to run multiple instances privacy friendly browser and isolate each instance for particular use cases
Configure each instance to be run over different VPNs (or no VPN at all)
Does Librewolf support multiple profiles like Firefox? If so that’s how I’ve always done it on Firefox. One Firefox install, multiple concurrent profiles. I even use Container Tabs on top of that.
