• When I run firefox v42 mac, the Preferences tab load as well

  When I run Firefox version Mac 42 on Mountain Lion, my homepage loads perfectly, but another 'Préférences' tab always seems to load as well. How can I stop this other tab from loading? Thank you, Ken.

  Hi Ken, one of the possible reasons are if the preferences page has been added as a second 'Home tab' in which case it will be displayed in each new window (Cmd + n) and every time that you click the Home button.

  To verify that you can use the preferences, the general Board, the section to start page, as described in this article: start-up, homepage, tabs and download settings.

  In the area of the Home Page, look for a vertical bar separating two addresses of character. A simple example with short URLS:

  https://www.mozilla.org/|about:preferences
  

  The bar certainly can be hard to spot with long URLs, but when you find it, delete everything to the right of the bar, then the bar itself (I suggest to remove the last bar so things don't accidentally get it together).

If you used the discount during the last update function - for example, Firefox says it's a bad performance and offers to restore some default settings - you have to do it again the installer of Kaspersky/Firefox.

  Delete all rules for Firefox in the list of permissions in the firewall and leave your firewall again ask permission to get full unlimited access to the internet for Firefox and the plugin-container and the update process.

• Unless my Firefox browser is actually updated (version 8.0.1), on my start page is displayed the message that I'm not using the latest version of Firefox! Is this a bug or is my pirate home page?

  I use Windows XP on a PC and Windows 7 on a MacBook Pro.
  In both cases, as my start page, I use "http://www.google.be/firefox?client=firefox-a & rls = org.mozilla:nl:official".
  Under the Googleframe remains the message "U used nieuwste van Firefox versie niet. Upgrade om het beste ITU internet het vandaag you halen! »
  False: my Firefox is already up-to-date.

  You are indeed updated. Firefox stopped using this address as its start page by default when 4.0 is released - page that you use can be (incorrectly) assuming that, if you are looking at him, you must always be on Firefox 3.6.

  If you restore the default home page , you should get more updated information.
