Using Edge, Brave or Opera?

  • Microsoft Edge, Brave, Opera and Vivaldi are built on Chromium and can install most Chrome Web Store extensions.
  • In Edge, open the store listing and allow “extensions from other stores” when Edge asks, then click “Get” / “Add to Chrome”.
  • Firefox and Safari use a different extension format, so Chrome Web Store items do not install there.

Permissions & privacy

Extension safety checklist

  • Read the permissions. “Read and change all your data on all websites” is powerful. Prefer extensions that only ask for what their job needs, such as activeTab or storage.
  • Check the developer and privacy tab. Every Chrome Web Store listing has a Privacy practices section where the developer declares what data, if any, is collected.
  • Install from the official store. Avoid .crx files from random download sites. Our pages only link to the official Chrome Web Store listing.
  • Prune what you don't use. Every extension adds a little start-up and memory cost. Remove the ones you haven't opened in a month from chrome://extensions.
