[DevTools Bug]: React devtools stuck at Loading React Element Tree, troubleshooting instructions are Chrome-specific

Repro steps

Load page, then open React DevTools. Reloading or closing and reopening the tab does not fix the problem. Quitting and reopening Firefox sometimes fixes the problem.

The linked troubleshooting instructions provide no guidance for users of browsers other than Chrome; I am running Firefox v114 (on macOS 13.2.1).

Hey @ialexryan, thanks for reporting this.

Can you please check if there are any errors in the extension's console when you are trying to use it? In Firefox, this can be done via debugging add-ons:

Then click 'Inspect' for DevTools extension and you should be able to check the console.

I'm having the same issue. This is what comes up in the console: TypeError: can't access property "executeScript", chrome.scripting is undefined

[ialexryan]

I actually hit this for the first time in a while just now. The error in the console was TimeoutError: Timed out while inspecting element 43.

Same issue but nothing in the console.

Also same problem. Nothing in console.

Hey, I've opened a PR with changes that should fix it - #27179.

Looks like extension doesn't work when mobile dev mode is enabled in Firefox.

Can anyone try downloading and installing a custom build from here to check if it fixes the problem for you?

devtools.tgz should contain firefox-extension.zip archive, which then can be manually installed in Firefox. Please also consider removing original React DevTools extension from Firefox before that.

@hoxyq That fixed it for me! Thanks!
