Since last week the Firefox browser keeps on opening automatically with 3 tabs till it finally hangs the computer. I searched with malwarebytes, trend micro antivirus, superantispyware, microsoft safety scanner, trend micro housecall but nothing happens. The problem still persists

If you have a set of 3 homepages, that would explain the 3 tabs at startup, but those other windows are a problem.

This article describes some troubleshooting steps to solve it:

Does that help?

It is possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.

Delete the files sessionstore.js [2] and sessionstore.bak in the Firefox Profile Folder.

If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well.
Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost, so you will have to create them again (make a note or bookmark them).
