Firefox Dev (60) Error CreateDesktop [CLOSED - DUPLICATE]

[eneerge]

Latest 5.24 on x64 Win10.

Firefox 60b1 launches fine, but in Firefox 60 b2 and b3, Firefox will not launch with error:

Code: Select all

SBIE2205 Service not implemented: CreateDesktop

Added

Code: Select all

user_pref("security.sandbox.content.level", 4);

to C:\Sandbox\user\SandboxName\user\current\AppData\Roaming\Mozilla\Firefox\Profiles\profilename.dev-edition-default\pref.js and that fixed it. Sandbox level 5 appears to be unsupported atm.

Hello energee,

This is not a new issue:

At the moment, the only supported level is 2:
