Web-bugs: www.eiger.io - Firefox is unsupported browser

[AntoineTurmel]

URL: https://www.eiger.io/

Browser / Version: Firefox 69.0
Operating System: Windows 10
Tested Another Browser: Yes

Problem type: Site is not usable
Description: The company is blocking access to Firefox, requiring only Google Chrome
Steps to Reproduce:

• I tried using the site normally, I get the error in the screenshot.
• I tried using the site with faking the user-agent (pretending to be Chrome and it's working.)

I reach out the support to ask about it, here is the response :

« Unfortunately, the browser version of Eiger is only compatible with Chrome. It is possible that using Firefox will result in performance issues with Eiger. We require use of Google Chrome because Eiger utilizes Google websockets. »

Thanks for the report @AntoineTurmel , unfortunately a special account is needed to sign in.
Good thing you gave us the screenshot, showing that Firefox is unsupported browser.

I'll move the issue to Needsdiagnosis for further investigation,

There isn't much to diagnose here without a login. Their page doesn't really load enough scripts to guess at why they wouldn't support Firefox; I can't even find that text being loaded (it must be loaded after logging in). My best wild guess is that maybe they are trying to print to 3d printers, and need something like WebUSB to do so. We'll have to contact them to find out.

@miketaylr, what do you think?

[miketaylr]

Yeah, I think reaching out is the right path forward. I'll shoot them an email.

We require use of Google Chrome because Eiger utilizes Google websockets.

:)

Given that @AntoineTurmel says it works with a UA spoof, we could consider sending an override here as well.

[AntoineTurmel]

They don't use WebUSB, only « Google WebSockets» seems to be the problem... but I didn't have any issues faking the useragent so far...
It's possible to create a free account online.

I got a response:

I have filed a software ticket within the context of this ticket for our Software team to review. One of our Software Engineers should contact you if this is a discussion that they would like to have.

So, fingers crossed someone gets in touch. 🤞

@AntoineTurmel is is still reproducible?

[AntoineTurmel]

Hello, yes, still reproducible.

Spoofing with Chrome this is not working. I get a

angular.element(document).ready(function () {
  var e, t;
  angular.bootstrap(document, [o.applicationModuleName]),
    (t = !1),
    (e =
      null != window.chrome || null != window.isElectron || window.Cypress) ||
      (t = navigator.userAgent.toLowerCase().indexOf("crios") > -1),
    (e || t) &&
      ((document.querySelector("#compatibleBrowserDiv").style.display = null),
      (document.querySelector("#incompatibleBrowserDiv").style.display =
        "none")),
    (window.ApplicationConfiguration = null);
});

because of

    (e =
      null != window.chrome 
      || null != window.isElectron 
      || window.Cypress
    ) || (
      t = navigator.userAgent.toLowerCase().indexOf("crios") > -1
    ),

so this is not a UA override but needs to define window.chrome is defined in Chrome.

This is what it looks like in Chrome.

on Chrome when once logged in with Google account.

and the websocket stuff is pretty standard in

@AntoineTurmel Did they mention any specific issues?
Could you point them to this issue here and that we are ready to help them if they had specific issues with Firefox.

@markforged is on github
I wonder if @mf-pherlihy could help us resolve this.
or @mf-alex-tsepkov
