Of the ~40 or so businesses I do general IT work for in New England, the ones with Comcast as the ISP are the least reliable. They experience significantly more downtime than any other provider.
What irks me even a bit more is that user experience is degraded even for logged in premium users. They just really don't want us using other browsers.
FF has been my dailer driver for a long time. But google blocking ublock origin was a deal breaker. I now only use chrome when a site is otherwise unusable.
