Google has banned AdNauseam from its web store, forcing it to be side-loaded. More recently Google has disabled support for Manifest V2 browser extensions — including AdNauseam. For those who still wish to use it, it can be launched manually as follows (adjusting your path as needed):
Mac
$ open -a /Applications/Google\ Chrome.app --args --disable-features=ExtensionManifestV2Unsupported
Linux
$ /usr/bin/google-chrome --disable-features=ExtensionManifestV2Unsupported
Windows
start "C:\Program Files\Google\Chrome\Application\chrome.exe" --disable-features=ExtensionManifestV2Unsupported
Note that the above workarounds are TEMPORARY and likely to be removed without notice. 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
- Download the latest adnauseam.chromium.zip file from releases
- 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
- In the Chrome menu, click Windows > Extensions or type chrome://extensions/ in the address bar
- Make sure the 'Developer Mode' checkbox is ticked
- 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)
- 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.

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:
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.
