Support and discussions for the x86/x64 Linux version of Pale Moon.
It's greyed out for me also (I use Linux as well). However, I don't really think this is a Pale Moon problem. I tested it on my wife's Windows computer and it doesn't even have the Current Page option. I think it's probably an OS / Desktop / Printing App bug (if it is even a bug or not). FWIW, it's greyed out also on Basilisk.
