how to reinstall firefox to overwrite unwanted version

So is you goal to have Firefox 8 installed?

Yes Some how I uninstalled it. Im new to Ubuntu and want to learn how things are done. Is the no way to just restore it???

Can you give the output of:

lsb_release -a; apt-cache policy firefox

Thanks

I have also downloaded the 8.0 but I know how to change the web browser. I have worked with computers for 30 years and could fix most problems at work without calling the help desk. but i am not a programmer I was a registration clerk. Thanks

Please provide the output of this command, as actionparsnip has requested:

lsb_release -a; apt-cache policy firefox

Run this command in the Terminal (Ctrl+Alt+T). After running it, select all the text in the Terminal (Edit > Select All), copy it to the clipboard (Edit > Copy), and paste it here.

Nothing shows except dorothy@dorothy-deskto: $ Sorry I know so little about this end THANKS for your yelp and patience

ok you have version 3.6 (as you can see). Do you want 3.6?

I wanted 8.0 at least thats what I though I had

Not yet. Run:

sudo add-apt-repository ppa:mozillateam/firefox-stable; sudo apt-get update; sudo apt-get install firefox

You should now have firefox 8...

I just want to be as up to date as possible. The system was telling I had an old version.

I THINK WE DID IT!!!!! THANKS SO MUCH FOR YOUR HELP My granddaughter had to show me how to copy and paste. Thanks again!!!!
