Yogi, sounds as if you've got problems. Looks as if the laptop isn't getting connected with the internet. One way to check is to see if you are able to get emails. If not, it' could be some setting that you need to tweak but it's probably easier for a technician actually there to try and work out what to do.
The Firefox problem could be unrelated. If you can get emails but can't get into Firefox first check that Internet Explorer browser is working. If that is but Firefox isn't, if you are able to get to the Firefox bowser page go to Help and select Restart with Add ons disabled. If that doesn't work, go to Help, Troubleshooting Information and click on the Refresh Firefox button at the top right of the page.
Internet explorer isn't working properly either, so I can't get onto Firefox that way. I haven't tried my emails on the laptop as I always go into them on the IPad, so I'll check that out later. Thanks El.
I think I've given up for today! Youngest son is visiting tomorrow, so I think I'll let him have a look at it, as he's much more computer savvy than me.
Forgot to add: There is internet connection as I was able to update my avg and itunes, it's just the browsers which won't open.
That sounds a headache Yogi, well done on getting as far as you did. I hope EL's tips work, it sounds as if you are at the last hurdle.
I hate to let things beat me, but I've given up for today.
