On Chrome on Mac, I am not able to create or edit messages on meta. When I try, the app hangs at “saving”, and I get continual error messages in the inspector:
POST https://meta.discourse.org/message-bus/d97.../poll net::ERR_BLOCKED_BY_CLIENT
This has happened every now and then, and has come back today.
I thought it might be the privacy badger extension, but turning that off did not change things.
