Profiles in Chrome and their ease of use (Cmd+Shift+M to open a new window in a different profile) is the primary reason I still use Chrome over Firefox. I have a Personal, a Work, and a Development profile. The development profile is where I install dev extensions like React Devtools, Redux Devtools, etc. because they require full access to all sites in order to function. I don’t do regular web browsing with devtools installed. These tools seem trustworthy, but why risk giving them access to everything I do on the web?

I’ve tried Firefox Containers and can’t find the same power and ease of use Chrome Profiles have.
