Sorry if this is not the correct response, but I could not find another way to contact the Simple Bookmarks Menu developer. If a moderator can let Mr. Seleznev see this, I would understand if this has to be deleted.
Dear Aleksandr Seleznev,
I have been using Simple Bookmarks Menu for a year or two, and love how it cleans all the crud out of my bookmarks menu.
I am writing you to, to encourage you to port this addon over to be useable by the Pale Moon browser. I have started using Pale Moon, but was unable to install your addon when surfing the addons.mozilla.org site. For what it’s worth, the AMO site sees me as using a version of Firefox that is 27.x. Even in the “Complete Version History” section of your addon page, none were compatible with versions of Firefox earlier than 29.
Would you be interested in porting your addon over to be Pale Moon compatible? I am not a coder at all, but there are a couple of links that I can give you, that would be helpful if you wanted to do this.

Regardless of what you decide, thank you for making a great addon!
Respectfully,
Paul Rittman
