Before you start
Safari is more restrictive than other browsers. It requires Xcode (free Apple program) to install extensions. The process takes about 30 minutes the first time. You need macOS Ventura 13 or later, Safari 16.4 or later. Don't worry if you've never opened Terminal, I'll guide you step by step.

Frequently Asked Questions
Do I need to keep the folder on my computer? ▼
Yes. The browser reads the extension files from the folder. If you delete it, the extension stops working. Put it somewhere safe (for example, Documents).
Is it safe to enable Developer Mode? ▼
Yes, completely safe. Developer Mode simply allows you to install extensions from a folder instead of the store. It doesn't change anything else in the browser.
The browser says "Disable developer extensions" - what do I do? ▼
Some browsers show a warning on startup when you have manually installed extensions. Just close the warning. The extension continues to work normally. When AdOff is on the official store, this warning will disappear.
How do I update AdOff? ▼
Download the new version from the site, extract the ZIP to the same folder (overwrite the files), then go to your browser's extensions page and click the "Reload" arrow on AdOff.
Does it work on all sites? ▼
Yes. AdOff blocks ads on all websites (banners, popups, trackers, social media, news, blogs). Video ad blocking on streaming platforms is available in Pro/Trial. You can also pause blocking on specific sites if needed.
How do I uninstall AdOff? ▼
Go to your browser's extensions page, find AdOff and click "Remove". Then you can delete the folder from your computer.
Which browsers are supported? ▼
AdOff supports all Chromium browsers (Chrome, Edge, Brave, Opera, Vivaldi, Arc) with 100% feature compatibility, Firefox with 95%, and Safari 16.4+ on macOS Ventura+ with 95% (requires Xcode). On Android use Kiwi Browser or Firefox. iOS support coming soon.
Does it work on mobile? ▼
On Android, install Kiwi Browser (free from Play Store) which supports Chrome extensions. On iOS, browser extensions aren't yet supported. We're working on it.
