ReactDevTools extension doesn't work in private Firefox windows [DevTools Bug]:

[ndejoma]

Website or app

reactjs.org

Repro steps

1. Install the ReactDev tools extension for Firefox ( I am running Firefox Dev edition Version 104.0b5 on Debian-Linux)
2. Allow the extension to run in private WIndows by going to Add-ons and themes (Ctrl + Shift + A)
3. Visit any website running a development or production of React in Firefox(I have tested Firefox dev Edition and FirefoxESR)
4. Open Firefoxdevtools and visit the components tab added by the Reactdevtools extenstion
5. I have tested a local dev build and a production build of React, and weirdly it works in non-private windows. But in Private windows, it doesn't see that the page uses React.
6. Below is a screenshot of what I see on both websites

This is probably because Firefox has stricter rules for extensions when you are in private mode. Is there anything you need to use devtools for that only works on private mode?

Hey Checkout this solution. https://support.mozilla.org/en-US/questions/1293505 Maybe this is the reason it's not working
