I need help in using the Safari tabs on my iPad 1. I hate them & I've tried but since I can't get rid of them as I've tried clearing history changing the private browsing, etc so I thought I would try to understand them. What can I do to leave them in the background? I don't need a link to where I was hours ago. What are the + & - sings for? I heard the Firefox is working on a browser that minimizes the tabs. Any word on that?
