Let me first introduce you to the main issue here. Have you ever used Firefox focus or incognito/private browser to look for something and Google keeps redirecting you to the French language or local language when you have a VPN enabled for example?
Basically, Google will not use the language set by the browser and instead it will use the local language based on your IP address given by your ISP or VPN provider. Since you’re not logged in to set your preferences.
Straight to the point below is the link for the English search engine with the safe browsing enabled to avoid malicious websites.
Navigate to your browser settings and change the default search engine by adding a new one, giving it a name and the link above.
Thank you for your support and visit and if you have other suggestions, please leave a comment.
