There are only 3 browsers these days pretty much:

Chrome, Safari, Firefox.

It really shouldn’t be hard to test.

Have you ever tested something in mobile browsers?

Also, a quick test is easy. But a quick fix - often not so much. Unless you want to break something else.

Edge and samsung internet are basically the same as chrome, so there are only 3 browsers to check. Especially that most stuff just works fine across the browsers, it’s not like cross-platform across OSs, it really is a bare minimum.

> It is hard justifying extra effort for those 2.2% marketshare, unless you count in idealism. And most companies are there for profit.

To me, this attitude always sounds like a local business owner choosing to randomly kick 1 out of every 45 customers out of his store. Is it really that much time/cost/effort to test one more browser?

"Is it really that much time/cost/effort to test one more browser?"

As someone who has over the years all in all spend months of work on catering to FF, I say yes.

It is not the testing. But the fixing of bugs that costs time. Time most buisnesses apparently rather invest elsewhere.
