Proxy Chrome extensions are not going to be usable in MV3
As a proxy extension developer, this is absolutely maddening. We're forced to choose between auth-less open proxies (bad), or baking in a wacky authentication scheme through a side channel (also bad). MV3 drops in 2.5 months, and will leave tens of millions of proxy extension users unable to use products they paid money for.<p>This is all on top of the many other issues with MV3 that Google is pushing under the guise of "improving performance".
