Pale Moon Update
 
We have been told by the Pale Moon guys "Things have been a bit crazy...sorry for the delay...". We have submitted v5.7.23 and will continue to submit the latest versions of CYS. When they decide to list it is entirely up to them. For now, the Firefox version still works with Pale Moon but not for long.
