Ubisoft.com - Can't log in

[Tomaso]

Issue:
Can't login @ Ubisoft.com

How to reproduce:
1) Go to https://account.ubisoft.com/
2) Fill in your account details, and click on "LOG IN".
(The loading animation never finnishes, and you can't log in)

Additional info:
* In Pale Moon's console:

Strict-Transport-Security: The site specified a header that could not be parsed successfully.

* Other browsers can log in just fine.

No such issue here. I get "invalid email address or password". Worth mentioning I use uMatrix to block unnecessary stuff, only allowed ubi* and akamai objects.

Workaround: open https://www.ubisoft.com/en-us/ in a new tab and close the login page.

This works!

The problem needs to be addressed though, because things like "Account management" (which requires another confirmation login) still can't be accessed!

The STS header isn't the problem. It'll just be ignored for being wrong.

What is the problem is, is "TypeError: Can't convert undefined to object", which is almost certainly Issue #816 (UXP).
Which is, by the way, a bounty-eligible issue. If you want to make some money, get on it!

I could probably do this, however, with my current build time (4h+) it would take ages...

I'll have a jab at the TC39 toString standards changes myself which is a prerequisite to the toSource issue here.
I'm wondering if toSource is simply not available, if it will be polyfilled by the framework that trips over this (GOG and Ubisoft alike). That would be a temporary fix if so.

My quick test shows that the TypeError: class constructors must be invoked with |new| error disappears when Function.prototype.toString is undefined.

g4jc's "SpiderMonkey Tuneup" is included in v28.7.0a1 (2019-07-20), right?
Unfortunately, this doesn't seem to help with the login issue @ ubisoft.com.

Testing done based to tinderbox builds using temporary account for test.

Great, sure hope that you've pinned it down then!
I were running Mozregression earlier, but was unable to come up with a conclusive result.
Think I found some builds from Apr.2017, which seemed to work randomly.
Guess I should have tested more thoroughly, with some later builds! :)

I'm sorry but that seems to be a problem to implement.

The Standard for typedarrays is ES2015 which we implement.
Using ToIndex in constructors and allowing constructors with no arguments is an ES2017 Draft spec which is a conflicting specification with what is standard (it would break standards compliance AFAICT by changing the definition of how constructors are used and allowed to be used).

Ubisoft should not be using it, or at the very least not without a polyfill, shim or fallback.

Thanks, Moonchild.
I've created a support case, giving them all the details and informing them of the problem.
