Refresh Driver was destroyed at an inopportune time. This could have lead
to memory corruption or a potentially exploitable crash. Note: This
advisory was added on December 13th, 2022 after discovering it was
inadvertently left out of the original advisory. The fix was included in
the original release of Firefox 106. This vulnerability affects Firefox <
