1421314 - Add Parallels Display Adapter to the list of supported graphics vendors (623338)

Status: RESOLVED FIXED

(Core :: Graphics, defect, P3)

Description

[alev]

User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:57.0) Gecko/20100101 Firefox/57.0
Build ID: 20171112125346

Steps to reproduce:

1. Install Firefox 57 into Parallels Desktop 13 for Mac, Windows 10 virtual machine
2. Open https://www.mozilla.org/en-US/firefox/57.0/firstrun/


Actual results:

High CPU usage (80% in my case)
Poor responsiveness, so it is not easy to enter a new address or close the tab.


Expected results:

Firefox works as fast as on a real PC.

---
A lot of Parallels users who installed the new Firefox in a virtual machine got to Parallels support with this issue. 

Current workaround proposed at https://wiki.mozilla.org/Blocklisting/Blocked_Graphics_Drivers "How to force-enable blocked graphics features" with spoofing graphics system information works fine and solves an issue with performance.

Suggestion is to add Parallels Display Adapter in the whitelist.

Is the policy still to whitelist certain virtual machine device vendors?

Alex, are there any other devices or driver versions that should not be allowed?
