Mostly Internet Explorer 7 and 8, some Mozilla Firefox builds. That’s what I had in mind when I said “old browsers.” The last project I worked on that still had to support browsers from that era was in 2018.

Sounds about right. Looking back I’d already moved IE7 to “functional” support in late 2016[1] and was planning to do the same to 8 and 9 in the not too distant future.
