Firefox has profiles too, but #Chrome's profiles are not a PITA to use, feel lighter weight, and play well with window management.
#Firefox's multi-account extensions are only useful for logging into the same website using multiple accounts. That's it. And despite general feelings about the feature, it has next to no security or privacy benefits (not since “Total Cookie Protection”). Using it for privacy purposes is basically privacy theater that just adds overhead.
#Chrome has always been ahead in terms of security. E.g., t took a really long time for Firefox to implement a permissions model for extensions, and then to give the ability to disallow some extensions in Private Mode. And right now, it doesn't have “click to enable” on extensions.
I'm a minimalist, but even I use problematic extensions, like LanguageTool (alternative to Grammarly). And if you're security conscious, you can't allow such extensions to access your security-sensitive services.
