First of all, Firefox works with default settings and has been installed recently. As soon as I open the home page, there is nothing displaying on the web address bar apart from Search Bookmarks & History. As soon as I access a site by typing in the address, the 1st url I typed in stays there even if i have browsed through other pages also e.g. will be dispalying www.where.com even if I have accessed Google through my bookmarks. Another thing that happens is that the Back/Forward buttons are shaded out sometimes on the 1st tab but have no idea or haven't noticed any particular pattern regarding this. When I go into Private Browsing, Firefox opens/loads two tabs and takes a while (a minute or so) to load them. When I close it down and open it again and go into Private Browsing doesn't do it the second time round. Also there are times that the 1st tab won't close down when i have multiple tabs open and it will only when are only two tabs left and by clicking the second one in line, Firefox will close without prompting for multiple tabs closing.
