Site owner: No

1) Navigate to: http://orbis.stanford.edu/

Expected Behavior: being able to browse the website.
Actual Behavior: a modal is shown, blocking the website's content.
Lovely, 
At the top of http://orbis.stanford.edu/orbis.js,
var browserTest = navigator.sayswho= (function(){
var N= navigator.appName, ua= navigator.userAgent, tem;
var M= ua.match(/(opera|chrome|safari|firefox|msie)\/?\s*(\.?\d+(\.\d+)*)/i);
if(M && (tem= ua.match(/version\/([\.\d]+)/i))!= null) M[2]= tem[1];
M= M? [M[1], M[2]]: [N, navigator.appVersion,'-?'];
return M;
})();
if (browserTest[0] == "MSIE" || browserTest[0] == "Firefox") {
document.getElementById("badBrowser").style.display = "block";
_gaq.push(['_trackEvent', 'errorEvent', "browser_unsupported, T: " + browserTest[0]]);
}
else {
startUp();
}
Unfortunately they don't explain why it's unsupported in IE or Firefox.
The "About" link on the app lists one Eljiah as the technical contact for the site--his email is at the bottom of https://dhs.stanford.edu/about/ if someone wants to reach out.
Faking Chrome UA on Gecko (Firefox).
The site is working.
I'm not sure why.
I wonder if we can help @emeeks to identify issues and/or remove the unwelcoming message? :question:
When faking the user agent to be safari on Firefox Desktop, I get a completely working site.

@emeeks could you remove the user agent sniffing. Thanks.
So I tried to contact again, but this time on twitter.
The answer is:
@webcompat That was necessary when @ORBIS_Stanford was created. I'm no longer at Stanford so can't update it now that FF has better SVG.
I sent an email at the project address.
trying to contact a second time.
Since we got a duplicate, trying to contact [email protected]
There was an automatic reply from @pfzenke
Could be possibly contacted at https://twitter.com/pfzenke/with_replies too
Removing "browser-ie" unable to repro issue in IE11/Edge
I sent a tweet as well: https://twitter.com/AdamOpenWeb/status/774025697752940544. This should be a simple thing to fix.
Received a response back on Twitter :)
I don't work on this project, but I can send this along to my colleagues
This issue still exists, tested in Firefox 53 for OSX.
Thanks @adamopenweb. I recently left Stanford. Orbis is maintained by CIDR. Here are the two main email contact addresses concerning the project: [email protected] and [email protected]. Happy holidays.
@pfzenke thanks for the info, I sent an email to those contacts. :)

Received a response over the holidays that someone will look into this issue in the new year. There aren't any active developers working on it, so it may take some time.
Issue continues.
Thanks @erkinalp, just sent an email to our contact to see if we can get an update.
I haven't received a response back since 2016. At the time they said there are no active developers working on this.
I'm going to close this as Won't Fix. If anyone disagrees and wants to reach out to them, please reopen.
It works in Firefox, but performs badly.
