I was worried about this when I originally switched from Chrome to Firefox earlier this year but I can honestly say I haven’t found a single site that I personally use that I had to go back to Chrome for. Any issues I had with any site were related to ad blocking using uBlock or DNS based blocking I also do.
I feel like most of these people were way over analyzing the questions. No reason to look for in depth meaning of possible answers, just answer them and take them at face value.
