there is no version 7 which exists according to changelog
github.com/react/react/blob/main/packages/react-devtools/CHANGELOG.md#react-devtools-changelog

does not work in next.js 16

It worked well but hasn't been updated in over a year. The app breaks with the latest React/Next.js libraries due to a bug with params and searchParams in Firefox. There is last 7.1 version in Chrome that works fine. Is Firefox still supported?

I was suspicious of the recent permission update that adds “input data to the clipboard”. I looked it up on GitHub and that is used to show a “copy to clipboard” button in the extension.
Note that this gives permission to write to the clipboard, and not to read the clipboard.

Very powerful app

I am excited to see how this helps me in the future!

Well implemented.
