If you keep running into errors when you're trying to install AdBlock from the Chrome Web Store, you can try "sideloading" it instead. That means installing the extension manually, using its .crx installation file.


Warning: It's safe to install AdBlock manually because you'll be getting our .crx file directly from the Chrome Web Store. In general, it's not a good idea to install extensions that you get from somewhere other than the Chrome Web Store.


Note: If you install AdBlock without going through the Chrome Web Store, you will not get updates automatically when we release them.


Note: Chrome 63 doesn't allow installing extensions from a .crx file. If you're using Chrome 63, follow the alternate instructions below.


1. Get AdBlock's .crx file

  1. Visit http://chrome-extension-downloader.com.
  2. Copy AdBlock's Chrome Web Store ID and paste it in the box on the site: gighmmpiobklfepjocnamgkkbiglidom
  3. Click Download extension.
  4. Click Keep when Chrome warns you the file might be dangerous. (It's not. This is Chrome's way of notifying you you're getting a Chrome installation file from somewhere other than the Chrome Web Store.)

2. Install it in Chrome

  1. Type chrome://extensions in the address bar to open Chrome's Extensions page.
  2. Enable Developer mode in the upper right corner of the page.
  3. Drag the AdBlock.crx file from Chrome's Downloads bar into the Extensions page.
    If the Downloads bar isn't visible, click Load unpacked extension on the Extensions page, browse to the location where you downloaded the file, and open the file.
  4. Click Add extension when Chrome prompts you.

Alternate instructions (no .crx file required)

  1. Visit http://code.getadblock.com/releases/.
  2. Download the zip file for the most recent release of AdBlock and extract it to a location you can find easily.
  3. Type chrome://extensions in the address bar to open Chrome's Extensions page.
  4. Enable Developer mode in the upper right corner of the page.
  5. Click Load unpacked extension, browse to the location where you downloaded the file, and select the extracted folder.
  6. Click Add extension when Chrome prompts you.
