Firefox has something like this called containers. The best example is one for facebook, where any call to any facebook servers only works in the facebook container. It has similar setups as well, Work, Home, Commerce, etc.
FF as far as I know does not have a way to do this as easily, you have to spin up different profiles and click through each one to configure it.
I still have chromium around for primarily this reason.
Opening my 'Shopping' profile brings up windows and tabs from where I left off. Same with "Social". When I don't want distractions, I just close those profiles. No notifications, no updates, etc. I like the separation.
I can't stand Chrome either and so I've been using these two together for about a year now I believe. Using a naked version of Chrome is jarring given my browser feels like it fits how I use it being setup like this.
