Are you talking about bookmarks?

I thought they were called tabs, but perhaps they are bookmarks. The tabs or bookmarks are located at the top of the screen to make it easy to click on if you want to see facebook or your email or whatever you look at frequently. That way you don't have to sign into whatever you want to see.

Hi, how did you have it setup before ? Where you clicking links in the tiles or are you running without tiles ? Do you have Firefox setup to open links in New Tabs or a New Window or just change the main page. ?

You can Right Click the Icon in the Toolbar where you startup Firefox.

Maybe it would be best for you to turn on the Menu Bar at the top of the Browser by mousing to the top and Right Click and Click on Menu Bar From File you can open whatever. You may want to turn on the Bookmark Toolbar and then you can drag and drop from the Padlock or Information icon the URL to Facebook or your bank.

as to why you need a new Firefox after having a Virus beats me. Next time come here and ask for Help.
