  • Problem Description

    If the LocalStorage plugin is part of your project and cookies are disabled in Firefox 43.0 (x86/x64) and onwards then C2 will throw a javascript error on preview. The error can be acknowledged and the preview will then work.

    This was reported to Mozilla back in 2012 and is still being shown as a new bug in Bugzilla.

    Description of Capx

  • Should be fixed in the next build. Because of the way Firefox handles this, in this case every attempt to access local storage will simply trigger "on error". At least it avoids the game crashing.
