Ignore assets from an extension in text compression audit

[grappler]

I have the Google Dictionary installed and when I run Lighthouse I get a message for /content.min.css text compression is not enabled.

It would be cool if Lighthouse could know what assets are being loaded by chrome extensions and which are being loaded by the site.

Lighthouse 2.2.1

Yeah, somehow installed extensions which alter DOM in any way interfere with lighthouse scanning process.

This might be not the case in Chromium 60 any more when lighthouse is directly integrated into the browser.

good catch @grappler thanks for the report! It's not possible to avoid false positives for all extension activity, but this is an easy case we're not covering.

We really just need to check that the scheme is not chrome-extension here if anyone is interested in taking this up :)
