How can I stop my tablet from opening a new tab every time I switch to Firefox? It’s the worst when I’m trying to get information quickly into another app. I’ve looked through all of the settings and it’s not there. I’ve tried typing about:config and it does nothing except show the new tab window.

Someone please help. I’ve seen an answer from a question about a decade ago but things have changed now and there is no “options” if that’s the next suggestion. All I see is Settings now, and no options to change this in there either. This should be obvious right?
