Support Tip: Workaround for Firefox to prefer JSON over XML


Are you using Mozilla Firefox to access the Intune Admin console and work on scenarios such as Android for Work or Volume Purchasing? If so, you may run into an issue due to recent change in Firefox to prefer XML over JSON. There’s a one-time workaround to change the default behavior of the browser; the fix below is from Brock Allen’s blog post:

  1. In the address bar in FireFox, type “about:config”.
  2. Click the “I promise” button.
  3. In the search bar type “network.http.accept.default”.
  4. Double-click the setting.
  5. In the comma-separated list add a new value of “application/json” (without the quotes) . Replace with “application/json;q=0.9” or another value of your preference.

Note that Mozilla will be removing support for Silverlight in version 52 of Firefox, effective March 2017. Please refer to the documentation page here for more information on supported browsers.

    Soooo…. what’s the deal with this? I’m just looking at Intune now as a demo, considering a big purchase of the SPE suite and I see that only IE 10, Chrome < v42, and…. Silverlight is required? Am I missing something, or is every other platform and management portal modern, except Intune Admin? Can you guys make this modern browser compatible and independent of agents like Java, Flash and Silverlight? And work on Mac running safari or Chrome, or…. any modern version of Chrome (they're on v58 now).

    Thanks, sorry if sounds like a rant, just kinda crazy to show up late to this Intune party and find out it's pretty out-dated in this one novel (but central to management needs) way.

  2. Hi, Chris – The new Intune on Azure (login to portal.azure.com) admin experience supports most modern browsers. You can see the list of supported browsers here: https://docs.microsoft.com/en-us/intune-azure/introduction/what-is-microsoft-intune .

      INTune in Azure doesn’t do anything at the moment. I am in the position now of not being able to access Intune at all from a Mac it seems. This is crazy. Microsoft, what are you doing?

      1. There’s a few customers that haven’t been migrated yet due to unsupported groups/etc. or inconsistencies in settings. However, many customers are migrated. If you’re having challenges getting to Intune on Azure, please open a support case. To login to Intune on Azure, login to portal.azure.com and then search in the left hand for Intune (you can mark it as a favorite to find it easily). The Azure console works on a Mac.
