Windows 7, HP Pavilion (originally Vista) PC, I have been using Firefox for a long time. Suddenly is produces 20 windows when i open the first one. Happened immediately after I upgraded my Maxthon Browser version. Coincidence ?

Chosen solution

What are in the unwanted tabs / windows?

Type about:preferences#general<enter> in the address bar.

There are two settings;

  • When Firefox Starts

When the browser is started, what do you want to display. Many of us choose Show My Home Page.

  • Home Page

When a new page is opened, what do you want displayed.

  1. Use Current Page. Use what ever page(s) are open at that time.
  2. Use Bookmark
  3. Restore To Default. about:home shows a Mozilla home page with tools.

You can use any of these that you wish;

about:home (Firefox default home page), about:newtab (shows the sites most visited), about:blank (a blank page),

or you can enter any web page or about: page you want.

You can check for problems with the sessionstore.js file in the profile folder that stores session data. When sessionstore.js is deleted you lose App Tabs and Tab Groups and open tabs and you will have to recreate them, so if necessary make a note or bookmark them.

You can use this button to go to the current Firefox profile folder:
