Can't log in to HA using Firefox ESR

[tjorim]

Home Assistant release with the issue:

0.88.x

Last working Home Assistant release (if known):
0.87.x

Browser and Operating System:

Tor Browser (based on Firefox ESR) and Firefox ESR (60.5.x).

Description of problem:

Trying to log into HA, I get the following error.

Logging in with Home Assistant Local.
Error: Message format incorrect: required key not provided @ data['client_id']

First noticed this when trying to access my HA over Tor.
On a new HA install I tried accessing it locally with Firefox with the same result.
Was working fine before the 0.88 series (issue was present in beta).

Javascript errors shown in the web inspector (if applicable):

custom elements and shadow DOM on Firefox ESR 60 is not enabled by default

custom elements

From version 59 until version 65 (exclusive): this feature is behind the dom.webcomponents.customelements.enabled preference (needs to be set to true). To change preferences in Firefox, visit about:config.

Add some additional information, even after change both options, FireFox ESR 60 is still not useable due the misalign of icons

[awarecan]

So, the iron-icon and lots of other polymer component are using :host() that only be supported after FireFox 61 (with turn on the shadow component support).

After apply #2860, I can login with FireFox ESR 60 with default settings.
