Netlux Adblocker appears to work with K-Meleon 74/75 and should be able to use the adblock plus macro with.
Becuase it uses a chrome file and has same adnlockplus in that chrome so the same macro can used or modified easily to fix small problems with it.

The Adblock Plus 7 macro opens the preferences for Netlux Adblocker.
Netlux Adblocker 1.0.2
https://addons.cdn.mozilla.net/user-media/addons/560072/netlux_adblocker-1.0.2-fx+tb+sm+an-windows.xpi
Should be renamed to {B1D4A368-709E-11E4-BE45-EA041D5D46B0}.xpi
I think it should br trssted becuase Adblock Plus 2.6.10 has be upgraded to work with firefox 29 and above. Also Who knows it when it mabe upgraded again to work with Firefox browsers newer than Firfox 31 or Firefox 38.
