This is why these days I roll my own extensions except for a few extremely popular ones developed in the open. Forget small QoL extensions, if I need it I write my own. Malware businesses routinely reach out to any remotely popular extension for acquisitions or “joint ventures”, it’s just too risky to install anything that’s not trust: ultimate, or known to be vetted by tons of people.

Btw, Firefox seems to have made it impossible to run extensions uncrippled from source without uploading to their server for signing. Utter madness.
