Firefox actually has a built in JSON viewer now! It's enabled by default on the normal release version as of version 53 - developer.mozilla.org/en-US/docs/T...

I also recommend BitWarden as another must have plugin for devs. We need to manage a lot of credentials and it saves a lot of time. And, unlike LastPass, it's open source!

Thank you for the comment Steve. I guess a JSON viewer would be an easy thing to incorporate into a browser.

A lot of the things you mention just provide functionality that's already built in
