How do you get page tabs to automatically delete when you close Firefox. I now have to manally delete all of them - dozen of them!
Each web page I go to leaves a tab at the top of the page above the website. They stay there until I manually delete them. My previous computer automatically shut them when I closed the home page

You can right click one tab and choose "Close Other Tabs" to close most of them.
Set the pref browser.tabs.closeWindowWithLastTab to false on the about:config page to prevent closing the last tab from closing the browser and make a close button appear if only one tab is open.
To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website.
If you see a warning then you can confirm that you want to access that page.
You can use the Filter bar at to top of the about:config page to locate a pref more easily.
