I use Safari with no plugins. Even Disney World has a broken website for buying tickets for me. The web is breaking because it's gotten way too complex and the fight against trackers is leading to random failures of things that used to work.
The web is breaking because we are reaching the point where developers are able to assume WebKit/Blink and get away with it. It is imperative that technical folk adopt Firefox to hold back the tide.
Which is a shame, but I would lay the blame squarely at the feet of the team who built a checkout that throws errors when their analytics events don't fire. QA should really include a manual run w/ an adblocker...
Thats true, but its quite likely that simply testing on a couple available browsers and avoiding browser specific checks means that safari (and other non mainstream browser) users will be fine.
There aren't really that many actual standards compliance differences between most browsers, the real problem is all the undefined garbage they are forced to run. Back when I ran a html/css/javascript validator in my browser it frankly shocked me the number mainstream sites that weren't even delivering valid html/css/javascript. In my experience developing a pretty dynamic web site (actually it was a management front-end for a rather complex application) most of our browser differences were caused by bugs that went away simply by providing correct code.
