I just shifted my entire workspace from brave to waterfox a few weeks ago! Now I have to do it again...

I know Librewolf exists, but I have reserved it for only personal and private use. I also know I could use containers too but my work use requires websites where I need the canvas API and DRM, and I don't want to unharden my Librewolf installation for them which is why I want to store my 'work' workspace in a separate browser altogether. Is there some other Firefox fork I could use for desktop?
