Is there a deal between Google and Cloudflare to make non-Chrome browsers harder to use? The pressure to use Chrome keeps increasing, and the amount of ad filtering you can do in Chrome keeps decreasing.
I would wager to guess its one of the nature consequences of Chrome being the most popular browser on the web. Most legit traffic will be from Chrome.
As someone who runs Firefox on both Linux and Android, with Enhanced Tracking Protection enabled, and tries to use web over native mobile apps wherever possible ... I really don't feel this at all?
only chrome was approved for use internally at cf 5 years ago when i left
I assume it's business people finding it to be a better "bang for their buck" implementation time-wise or lazy developers who don't use Firefox for their testing phase. I've seen it so many times. At a previous company, I was the only person using Firefox daily and I would catch bugs a few times a year during PRs for things that worked fine in Chrome, but not in Firefox. Oftentimes the suggestion was just to leave it because "who uses Firefox?"
