One more vote for this - I’m forced to use Chrome just for Gmail + the Hubspot extension. Currently 1 tab open in Chrome for gmail and it’s using 49% of processor load. Safari has 48 tabs open (inc gmail in one) and it’s using 2.7%. Enough said. It’s really not a tough technical challenge to add support for Safari, but hubspot are not exactly known for their engineering prowess, so I don’t hold out much hope tbh.
