Install AdNauseam on Chromium based browsers

Google has banned AdNauseam from its web store and left users with no access to their data. Follow these instructions to install it anyway.

⚠️ Important: Chrome support for Manifest V2 is ending

As of July 2025, Google has begun disabling support for Manifest V2 browser extensions — including AdNauseam. In order to continue using it, please following these steps:

1. Visit chrome://flags/#allow-legacy-mv2-extension

2. Enable "Allow legacy Manifest V2 extensions"

3. Restart Chrome
   
   Note that the above workaround is temporary and Google could remove it at any time. We strongly recommend switching to a browser that respects privacy and user freedom, such as Firefox or Brave. See the browsers that AdNauseam is fully compatible with.

Install AdNauseam

Attention: As of 2022, desktop chromium-based browsers no longer extensions to be installed with the .crx file, only via the "load unpacked" folder method explained below.

Manual Install in Developer Mode

1. Download the latest adnauseam.chromium.zip file from releases
2. Extract the zip file to a folder where it can remain after install

      Warning: Do not delete this folder after install or the extension will be disabled

3. In the Chrome menu, click Windows > Extensions or type chrome://extensions/ in the address bar
4. Make sure the 'Developer Mode' checkbox is ticked
5. Click 'Load unpacked extension' and go to the folder from step 1. Make sure you select the folder called 'adnauseam.chromium' (without a version number)
6. If you have previously exported your ads, you can now import them

* Note that each time you restart Chrome you may be prompted to Disable Developer Mode Extensions.   Hit Cancel and continue.

This is annoying, as Google intends, however there is a workaround for advanced users on Windows and MacOS. Unfortunately we don't know of workarounds (as yet) for other platforms.

Manually Updating AdNauseam on Chromium

To update AdNauseam manually while keeping your data:

1. Backup your data (optional, but recommended)

2. Locate the existing install folder:

   • Go to chrome://extensions/ (or brave://extensions/ in Brave, etc.)
   • Click Details under AdNauseam
   • Check the Source field for the folder location

   

3. Download the latest adnauseam.chromium.zip

4. Unzip the file and overwrite the existing adnauseam.chromium folder with the new version

5. Return to chrome://extensions/ and click Reload on AdNauseam

Reimporting Your Saved Data (Optional)

⚠️ If the folder was correctly replaced, all your data (ads, settings) will remain intact — no need to reimport your data again.

1. Open AdNauseam settings
2. Scroll to the bottom and click Import Ads
3. Select your previously exported .json backup
4. Your saved ads will be restored

---

Backup your data

If you're a new AdNauseam user, or don't need your saved ads, jump to Installation

1. Click on the AdNauseam icon in the toolbar
2. Then click the View Ad Vault button
3. Then click EXPORT at bottom-right

Retrieve your saved data

1. After you have AdNauseam up and running again, go back to the AdNauseam settings page
2. Scroll all the way down again and click ''Import Ads''
3. Choose your backup
4. You're all set

Using AdNauseam on other browsers

If Google has lost your trust, as it has ours, you might want to move to a browser that is not as intrusive and controlling. You have a number of options including:

• Go back to Firefox, or a derivative like WaterFox
• Try one of the many non-Google versions of Chromium, such as:
  • Brave
  • Ungoogled Chromium
  • Comodo Dragon
  • Vivaldi
  • Centbrowser

Optimal configuration for Ad Collection on Brave

Brave blocks Ads by default and trackers, so if you want to optimise its configuration in order to have the most amount of ads collected and clicked, change the "tracking and ads blocking" to "Disabled". AdNauseam will still continue to be blocking trackers and hiding ads, but clicking and collecting the most of them as intended by the extension.
