Add a new tab
Sorry if you can’t add a new tab in Firefox Focus like you normally do in other browsers. In Firefox Focus, you can tap and hold on a link, and choose to open the link in a new private window to open a new tab.
Add-ons support
We have designed Firefox Focus to be a simple browser. If you’re looking to utilize add-ons, please consider using Firefox for Android, which currently offers a limited set of trusted add-ons.
Change theme (light/dark)
You can change the theme to light or dark in Firefox Focus. Please read this article for instructions.
