Firefox autism

Firefox is one of the few options to Chromium variants. You can filter network calls from devtools quite nicely.

As a poweruser example, you can filter all calls going to a certain domain:

-domain:tiles.mapsy.mapper.fi

This will filter out all the map tile calls from a domain. This reduces clutter and makes it easier to focus on non-map related calls.

Another example would be filtering non-GET/OPTIONS calls:

-method:GET -method:OPTIONS

UPDATE

Keep only failed requests:

-status-code:200 -status-code:201 -status-code:204 -status-code:300 -status-code:301 -status-code:302 -status-code:303 -status-code:304
