[REQUIRED] Describe your environment

  • Operating System version: Windows 10
  • Browser version: IE11
  • Firebase SDK version: 7.13.1
  • Firebase Product: Firestore

[REQUIRED] Describe the problem

Firestore (both memory-only and standard versions) breaks on IE11 with version 7.13.0 and 7.13.1

Everything works fine on 7.12.0

The first error is:

SCRIPT5009: 'crypto' is undefined

Which is easy to fix with a pollyfill
var crypto = window.crypto || window.msCrypto;

After that, this error pops up:
SCRIPT438: Object doesn't support property or method 'forEach'

I think this is caused by this PR:

Specifically this line:

This is a Uint8Array, so it needs to be pollyfilled like this:
Uint8Array.prototype.forEach = Array.prototype.forEach;

I don't think these pollyfills are included in @babel/preset-env or the core-js all in one script

This will be fixed in the next release.
