1616635 - Disable or remove WebChannel support

Status: REOPENED

(GeckoView :: General, task, P2)

Description

[Christian Sadilek [:csadilek]]

It appears web channels are only used for FxA and now covered by web extension functionality provided by A-C. Since it's unneeded and can interfere in content scripts, I suggest disabling or removing it, if possible.

I recall there being a handful of other consumers (e.g. some sort of SUMO integration) but I can't think of any.

A reminder to myself that if/when we manage to fix this in GeckoView, we need to remove the workaround put in place on the FxA side here:

I believe this happened in Bug 1593395.

Reopening, because we're still seeing web channel related errors in our FXA extension. These errors are irrelevant, and can be ignored, but would be nice if we didn't ship this code, if not needed.

Tasks should have severity N/A.
