-Quick Answer
Atlas Browser is built on the Chromium engine (same as Chrome and Brave). This means it is 100% compatible with the Chrome Web Store.
How to Install Extensions (Step-by-Step)
1 Open the Chrome Web Store
Since Atlas uses the Chromium core, you don't need a special "Atlas Store". Simply navigate to chrome.google.com/webstore in your Atlas browser.
2 Click "Add to Chromium"
Find the extension you want (e.g., uBlock Origin, Bitwarden, or Grammarly). You might see a button that says "Add to Chrome" or "Add to Chromium". Click it.
3 Confirm Permissions
A popup will appear asking for permissions. Since Atlas isolates site data by default, extensions act normally inside their sandbox. Click Add Extension.
4 Manage Your Extensions
You can access your installed plugins by typing atlas://extensions (or
chrome://extensions) in the address bar. From here, you can pin them to the toolbar
or enable/disable them.
Top 5 Recommended Extensions for Privacy
While Atlas blocks trackers out of the box, these extensions add an extra layer of utility:
- Bitwarden: The best open-source password manager.
- uBlock Origin: For cosmetic filtering of annoying page elements.
- Dark Reader: Force dark mode on every website.
- ClearURLs: Removes tracking parameters from links (e.g., ?utm_source=...).
- LanguageTool: Grammar checking without sending data to Google.
Troubleshooting
"Extension Manifest V2 is deprecated"
Google is pushing "Manifest V3" which limits ad blockers. Atlas Browser will continue to support V2 extensions (like the full version of uBlock Origin) for as long as technically possible, unlike Chrome which is disabling them in 2025.
