Firefox Focus Isithangami Sokwesekwa

In choosing a search engine, I found out from the directions on Firefox focus how to add them. But when they gave the string for Wikipedia, it did not work. I was wondering if any knew the accurate one and also is there a webpage that gives search strings for many apps or web pages? When I did a search under “Wikipedia Search Engine String”, I didn’t see a web page that offered it and I couldn’t find it on the Wikipedia site. If someone doesn’t mind, can you give me the directions on how to find them? I would be very grateful.

When I do a search in the recently downloaded Firefox focus, I am still directed to google. Is that how Firefox focus works.? And I thought I would be searching the Internet through Firefox and nothing would be going through Google. The default search engine is still set for Ecosia and there is no option to use Firefox. Did I do something wrong here or is that the way this works?

Hi. I was searching FireFox Focus and I couldn't save an interesting URL I found, since I closed the browser by mistake.

Is there any way to recover it? I know the point is that FireFox deletes you data, but I'm trying my best. Thank you very much.
