Is it possible to hide extension resources in the Chrome web inspector network tab?

Not quite the solution I was after (I'd have preferred a global setting), but there is now a way to filter out requests from extensions, as mentioned by a commenter on the issue I originally opened.

In the network tab filter box, enter the string -scheme:chrome-extension (as shown below):

This is case-sensitive, so make sure it's lowercase. Doing this will hide all resources which were requested by extensions.

This is currently impossible. Please file a feature request on crbug.com.

When the post was first answered, it was not possible, The OP then requested for it here https://code.google.com/p/chromium/issues/detail?id=239401 and now it is possible.

Just enter "-f" in Network field
