Exthouse – Analyze the impact of a browser extension on web performance

I'd count that as yet another evidence that the recent move from Google to reduce the power of ad-blocking extensions cannot be justified by «performances concerns for their users» as they said earlier, since µBlock Origin has zero overhead in this benchmark.

Interesting, but I&#x27;m currently running 61 extensions in my Chrome non-private sessions, without noticeable impact, so I&#x27;m not overly concerned that extensions affect performance.<p>The thing that bothers me about extensions is that I have usually no control whatsoever over what information any extension might think they need to phone home about. A tool that logged this per extension would seem more useful to me. Not sure if this is even possible?

Hopefully more tools like this encourage extension developers to think about performance.

It gives uBlock Origin a score of 100 in the Screenshots, but does this actually translate to 100% performance compared to page load without extension?
