I am also experiencing this issue.

Firefox Extension Version: 4.27.1
My local npm package is version 4.27.4-a8f2653fa

Could the mismatched versions be the cause? (This most likely is a stupid question).

This seems to happen more often when you have multiple tabs open on different domains with devtools also open for each one. That's what's happening right now.

FWIW it's happening on the React site itself, e.g. https://react.dev/learn/describing-the-ui so it's pretty reproducible. I have a localhost:3000 react app running in another tab.

I had to "end task" for the tabs and dev tools process to get it working again.

Hey @kamranayub,

I had to "end task" for the tabs and dev tools process to get it working again.

Can you please elaborate on the steps to fix this?

Thanks!

@kamranayub Can you please share a list of steps which result into facing this error?

I've tried opening multiple (4+ tabs) at the same time, both production and dev builds of React, refreshing pages and reloading Chrome DevTools panels, but cannot reproduce it.

I know that reproducing this can be random, but I am happy to follow the same steps if this errors pops up more frequently for you.
