When I closed Firefox and then reopened it, all tabs that had been open, opened again. Since the last update this is not happening anymore and I can't figure out how to fix it. Now only the home page opens when I reopen Firefox. Please help

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 webpage or about: page you want.

Having more than one version of a program may cause issues. You must remove the older programs. Then get the current full installer.

Security Issue: Update your Adobe Reader Version 2015.016.20039 Note: Other Software is offered in the download.
