Add-on summary

Analyze keywords

Block Site is a browser addon to help you block desired websites. To operate, simply right-click on any webpage and then click on the "Block this website" context-menu item. The website will be added to the block list. Please note, the whole domain will be added to the block list, not just a URL. To change this list, open the options page, and remove the desired item.

For any blocked domain, you can add a redirect URL in the options page. So instead of blocking a page, the website will be redirected to the desired URL. There is also an option to block desired iframes. To do so, please add the URL (for the iframe) in the designated area on the options page.

Note: to report bugs, please visit addon homepage and fill the bug report form.

"can't block domains"

This was supposed to be for Android by this link as said so? But no! It does not support to be as an add-on when pressed even to download it manually. It worked great for me on my desktop but this is a lie for android. Either make it truly working for Android or have this useless page for Android add-ons removed. It appears Firefox hasn't really pushed up more add-ons for android devices for very long since. It has become a bore to use android with so much limitations.
