## Summary Fixes #26756. DevTools is failing to inject `__REACT_DEVTOOLS_GLOBAL_HOOK__` hook in incognito mode. This is not happening straight-forward, but if extension is toggled on and off, the next time I try to open it I am receiving an error that content script was already registered. <img width="676" alt="Screenshot 2023-05-02 at 14 36 53" src="https://user-images.githubusercontent.com/28902667/235877692-51c5d284-79d9-4b00-b62e-d25d5bb5e056.png"> - Unregistering content scripts before attempting to register them again. We need to inject `__REACT_DEVTOOLS_GLOBAL_HOOK__` on each page, so this should be expected behaviour. - Fixed error logging ## How did you test this change? Local build of extension for Chrome, trying the same steps, which resulted in an error. No regression in performance, tested on react.dev, still the same.
This is the source code for the React DevTools browser extension.
Installation
The easiest way to install this extension is as a browser add-on:
Local development

1 Note that at this time, an experimental build is required because DevTools depends on the createRoot API.
To install all necessary dependencies, run the following command from the root of the repository:
yarn install
