Did anyone actually see this extension run rather than just be downloaded?

When the article says “it was sideloaded without consent [...] this is what it looks like” etc - does that mean that’s what it looks like to users that did not opt in?

I get that just having it listed is creepy and wrong, but I fail to see why we’d scream about forking Firefox unless anyone actually had an extension do anything without their consent.

I don’t want unwanted extensions downloaded either but as long as they aren’t being run I’m not switching back to Chrome over it.
