1437863 - No content displayed in 64-bit Firefox with Citrix Receiver

Status: RESOLVED WORKSFORME

(Core :: Security: Process Sandboxing, defect, P2)

Description

[Jim Mathies [:jimm]]

Reported on the enterprise list.

Note, switching to a 32-bit build apparently solves the issue.

1.	Trying to do Firefox within Citrix alongside of other browsers. FF 58.0.2. 64-bit on Server 2016 / Citrix 7.9.
2.	When I run Firefox from Citrix Receiver, it launches fine.
3.	Typing items in the search bar demonstrates that pre-fetched searches / internet connection is working… https://cl.ly/3C3C1f3K2o16 
4.	Then clicking upon / doing directly to any URL… gets me this:  https://cl.ly/1P2l31001I1u 
5.	Other browsers are cooporating from within Citrix Receiver client. Problem this moment is only FF. 
6.	Also.. Going to about:config .. same. Just nothing. Cannot access while using Citrix Receiver. (Works fine while ON the Citrix server.)
7.	About:preferences.. does work.. and my thought was to turn off Hardware Acceleration.. which is now set like this: https://cl.ly/2e3a221t0A45 
8.	When I run Firefox from within the Citrix server itself.. All is perfectly perfect. All webpages load as expected.
9.	The key takeaway though is.. The “New Tab” … animation is going. (Super small animated gif / video demo: https://cl.ly/3F1n2G2k1z3p ) and the page never loads.

I had similar issues with Citrix and FF, performing this fixed it: https://support.citrix.com/article/CTX107825

From that support article seems like the issue is with Citrix's API hooks and is fixed in a later version.

If that's not the case then I guess we'll need some sort of Citrix set-up to be able to debug this.

90-day free trial of the whole XenDesktop product. Unfortunately you have to set up the backend as well. I've reached out to their sales team to see if they can suggested more reasonable alternatives.

I'm in contact with Citrix. I'll be getting a demo and talking with engineers about testing we can do and also what kind of testing they do internally for releases.

I contacted Citrix and they say they haven't seen any reports of this.
