MEDIUM 5.3EPSS 1.44%

Does this matter?

Lower severity and a low EPSS score (1.44%). Track it; it rarely justifies an emergency change on its own.

Description

If cursor visibility is toggled by script using from 'none' to an image and back through script, the cursor will be rendered temporarily invisible within Firefox. Note: This vulnerability only affects OS X. Other operating systems are not affected. This vulnerability affects Firefox < 58.
