Thanks for pointing me to LibreWolf. I like to use separate browsers as information silos and have been using Brave as my secondary. Been looking forward to switching it out for a long time, LibreWolf sounds like just the ticket.
Paired with the Foxytab plugin to automatically open websites in specific containers or restrict containers to a list of websites. Firefox also has profiles, and a simple extension (with a tiny thing to install in your PC) makes them as easy to use as they’re on Chrome
