Place it in Documents\Blockland\Add-Ons.
Because sometimes there are old blockland directories and the launcher runs the game from Documents/Blockland/ by default and sometimes ~/Blockland/ on linux. If not, post a console.log, maybe there was an execution problem with the add-on.
Where do I find console.log?
Blockland/console.logSimply download RTB, open it in the folder (for internet explorer press Save and then open the directory) then copy it, go to Documents, Blockland, Add-Ons, paste it.

If it kept showing an error, that means you had Blockland open while you tried to look at the console.log.You can't do that.And it isn't even ATTEMPTING to load Return to Blockland.You're obviously not putting in the correct Add-Ons folder.
