Question

Can't access devices through EDM since Firefox update 64.0


We're running a lot of ERS4500 series switches ( just under 100) with Avaya v5.7.2.012 firmware. Also a small number of ERS3500 that are experiencing the same issue and our ERS8800 with Firmware 7.1.5.2

Since the Firefox browser update to V64.0 we are unable to access any of the switches using EDM. After the initial login completes it shows '"Discovering Device, please wait' but never progresses.

We have found that devices with Extreme branded firmware :v5.3.8.014 are still working.

When we open the Firefox Web Developer - Debug console we see a message like the following;
TypeError: webServerName is undefined[Learn More] edmContentJs.js:1631:299

We are having the same issue since the Firefox update.
My work around at the moment is to downgrade to 63.0.3 and then set it not to auto-update. I've stuck it on a Virtual Machine we use just for remote management. That's a reasonable solution for us as we don't use EDM so much but we couldn't do without it either.

You can find the download here.

Thanks! Your mention VM made me think for a sec.

Our VM updates are handled differently than our physical machines, so fortunately our VM's still work. Just a bit of hassle if i'm not in that VM already.

Yeah, EDM is easier for some things, CLi for others, its an odd mix.

Thanks again for the suggestion!
Running an old version of browser is never a good idea in my books (band aid yes, fix no).
IE 11 and edge works but might as well be running old firefox.

Having the same issue with firefox V64 on 4900

Isn't the problem with the certificates and that firefox blockx the certs which use older technology?
It was the same problem in the Avaya era where you were always trailing behind with your browsers.

Perhaps in the latest software it is fixed and the webgui will use newer certs, but I am not sure about this.
For the VSP this was the same problem that TLS 1.2 was not supported and we needed to wait for a specific version to get it supported and working in all browsers at that point.
Unfortunately Microsoft, Google and the Mozilla group are constantly updating their browsers.
ERS4500 and ERS8800 are both End of Software support. It is not the switch's fault.
ERS4500 last release was v5.7.3 and ERS800 was v7.2.26. There is still hardware support but for updates, you should be running the last version.


ERS3500 is still being updated. I believe 5.3.9 is the last release. it will have better browser support.
Along with the ERS4800/4900/5900 and all VOSS switches, as their OS's are being updated regularly.


As a workaround I keep an 12-14year old laptop running a 5year old LINUX distro. And I just never update the browser.

Agree. As a workaround I keep an 12-14yr old laptop running a 5yo version of Xubuntu. Very solid.
And I just keep the laptop air-gapped when its not in use. I only use it when I have to. I only use it to visit the web-interfaces for switches I control.
For what it's worth, Firefox ESR 60.4.0esr resolved this issue for us.
Firefox v64 added/fixed Bug 1398718
This change how MFF browser manipulate response headers -> XMLHttpRequest.

Due to this browser API change, EDM (as a client application) on older ERS releases (e.g. 8800) it's no longer processing server response.

To bypass this you can:
a. Use IE11/Edge browsers instead of latest Firefox (current v64);
b. Downgrade MFF to v63 if want to use this browser instead of Microsoft flavors;
c. Update box image to latest version. Some releases have already support for latest MFF or Chrome browser.

This behaviour is even evident on ERS4950GTS with 7.1.0.007 and VSP 8404 with 6.1.1.0 and ERS5952GTS with 7.4.0.10
So even our newest switches have this issue.
Do you know if Extreme is going to be addressing this issue?
* EDM on ERS49/59xx platforms fixed this along 7.5.0.0. Please update to any of 7.5.x or 7.6.x.
* EDM on VSP/VOSS platforms starting with 6.1.3.0 do full support Firefox & Chrome browsers. Please update to any of 6.1.3 or above 7.x -> 8.0.

As previous note, the issue seen in EDM along Firefox v64 is due to an internal browser API change. Mozilla Firefox is moving to align more and more with Chrome browser for internal APIs.
