Having problems with a website

The website teaches Spanish language verbs. It is http://verbly.io/
I get a completely blank page in Pale Moon. It works in Firefox and Chrome. I tried user agent switcher to no avail. I tried Pale Moon with add-ons disabled with the same results.

There's certainly something wrong there. After almost a minute, it had finally transferred all of 18MB of JS (of a file that was marked as being only 1 MB...?) before halting.

At that point, it complained about JavaScript "classes", which may be the root cause of the problem, but with that kind of a JS-blob it's anyone's guess.

I notice in the Browser Console it says "SyntaxError: class is a reserved identifier". Googling that brings up a mozilla developer page that says Javascript classes started being supported in FF45, Chrome 49, etc. and not at all in IE, so I tried it in IE and got the same blank page. I'm guessing this isn't supported in PM so far.

JavaScript Classes (which are syntactic sugar more than anything else) aren't supported in Pale Moon yet, correct.
See also: Issue #1243 A bounty is available for anyone completing its implementation.

I hope this gets fixed, it's starting to be more common.

It's not that simple. ES6 classes is trying to force a language spec into JS that is alien to it and has a lot of pitfalls and risks attached to it.

If people want to become a web developer, they should be learning the core of the main scripting language in use on it, instead of trying to impose different language ideas upon it.

Good and nice, but that requires someone with special knowledge in that category, ecmascript specifications are a completely different beast. So, if you know someone who has coding knowledge and could implement that or can be of any help, feel free to forward them to Moonchild :)
