I use Firefox with both profiles and container tabs. Profiles can have differing addons, while container tabs can't. One profile has no ad blocking, for the extremely rare occasions when there's a site that I actually want to view that doesn't work with ads blocked. One profile is for testing. The other is for regular browsing.
