I‘m on the other side of that. I'm constantly throwing large amounts of HTML at Firefox and it just goes on normally, literally 0 slowdown. Add some VueJS for additional fun. I deploy and get Chrome users complaining about performance. One example is that one can not add more than a few hundred options in an Options Select list in Chrome. You can throw literally 10'000 at Firefox. Similar stuff with text fields having 10'000s of rows.
