This is a tutorial for everyone who hates installing add-ons from the forums. The easiest way i find, to instantly install add-ons to your blockland folder, is to get an extension called "Download Them All!". Currently, there is only a firefox version as far as i know. So, if i ever find out that it is there for any other browser, i will put it in this post. This, to me, is just as quick as using the Mod Manager.
I provide images to show you exactly how to set up, and use dTa.
How to setup dTa
Install "Download Them All!" - Firefox:
https://addons.mozilla.org/en-US/firefox/addon/201/
Click Tools -> DownloadThemAll! Tools -> dTa One Click

Note: If you get an error message, just click "Ok" And the dTa 1 click manager will open.
Click the folder next to where it says "Save Files In" And locate your blockland add-ons folder and click Ok.


Now that dTa is set up, i can show you how to use it to download add-ons.
How to use dTa for Blockland Add-ons
Go to the add-on you want to download and click the download link.
Download the add-on, but when the download dialogue pops up, click dTa One click and select the add-ons folder.

And you're finished! As soon as the download is finished, the add-on is now in your blockland folder and ready to be used! Now, those people who don't like downloading add-ons from the site can get add-ons that arn't on rtb!
That's my tutorial, thanks for reading, hope this helped you all.
