How to get for example Adblock Plus working on Chrome/FreeBSD (workaround):

1) download the extension as a *.crx file, 2) extract it into a folder, 3) drug
and drop this folder into the "extensions" tab in Chrome (chrome://extensions/,
"Developer mode" must be activated).  

To download an extension (Adblock plus as example) from the Chrome web store
I've used Firefox, since Chromium will not let you save *.crx files for
security reasons. In Firefox you go to the Chrome web store, search for Adblock
plus, click it, copy the URL of this website
(https://chrome.google.com/webstore/detail/adblock-plus-free-ad-bloc/cfhdojbkjhnklbpkdaibdccddilifddb). 

After that go to the site http://crxextractor.com/ , click "Start for free",
insert the copied  link from the Chrome web store into the field "URL from
ChromeWebStore" (see the left side on that page). Download the *.crx file. 

On the right side on http://crxextractor.com/ you see "Drop downloaded .CRX and
get source code". Drop or load the *.crx file you've just downloaded and save
the resulting *.zip file. 

This *.zip contains a folder with the extension. You should extract it on your
disk ("Extract Here"). The extracted folder you just drug and drop into the
"extensions" tab in Chrome (chrome://extensions/, the "Developer mode" in the
top right corner must be activated).

I've just tried to install "Adblock Plus" and "ublock origin" this way -
everything worked fine. I hope, this will help a bit.
