To make Google the persistent default in Firefox, choose it under the browser’s Default search engine setting. On desktop, go to Menu > Settings > Search. On Android, tap the search-engine icon in the address bar, open Search settings, then choose Default search engine and select Google if it is listed.

One-time Google search or a permanent default?

Selecting Google from the address-bar search-engine menu can use it for a single search without changing Firefox’s saved default. To have later address-bar searches use Google too, change the Default search engine setting for your platform.

If Google is missing or the setting changes back

Google is not in the list

Firefox’s built-in search-engine options can vary by region and language. Mozilla documents adding a custom engine; the controls depend on the platform and Firefox version. For Android, open Search settings > Default search engine > Add search engine if that option is available. Mozilla’s Add or remove a search engine in Firefox help page gives Google’s search URL as https://www.google.com/search?q=%s. The %s represents the place where Firefox inserts your search terms.

The default keeps changing

Review your installed extensions. Mozilla notes that an extension can set a new default search engine. If an extension changed the preference, check its settings or disable it, then select Google again under Firefox’s Default search engine control.
