GoogleBot Extension On John Mueller's Browser?

John Mueller presented at SEO Day virtually and someone noticed that on his Chrome browser was this little robot extension and shared a screen shot of it on Twitter. I am not sure what it does but I would guess it does some internal debugging related to Google Search and is not a public extension. I can be wrong.

Turns out this is a public extension named The Great Suspender - now I look foolish. :)

Here is a screen shot:

But we have internal extensions we use in my company to make our jobs faster. So I assume Google has such things internally as well.

Any guesses what this extension does?

Remember we saw in John's browser a Google penalty server years and years ago?

I hide most of them. Muahaha.
