Tried to Google answer. Confusing. Can you help?

I recently posted about a problem with my new(refurbished) computer. Thanks for the advice given. Everything is working fine now but there are a couple of quirks. The computer now has 2 hard drives per the job of my former guru. Nothing I can do about that.
Don't really know why this was done but since things are OK, no problem.

My question. Why, when I open Firefox and go to one site or another, does the darn thing keep opening multiple tabs? I have a laptop with Firefox and this does not happen on that machine.
The new desktop is my problem. I tried to see if there was something to 'un-check' but can't find anything. Several results of my 'Google' told me to do things with which I am not comfortable. You know I'm a computer idiot.

There must be a simple way to prevent Firefox from opening multiple blank tabs. Anyone know a simple way to stop this from happening. As am experiment, I just opened Firefox and bounced from one site to another by way of Favorites(bookmarks) and then Xed out. It just asked me if I was sure wanted to close 6 tabs or if I want to continue. Phooey. Just let me close the thing! I don't need these blank tabs.

Windows 7. Firefox and IE as browsers.

Help!

2. This should fix it.

Restore the default home page

If you want to delete your home page customizations, this is how to do it:

Click the menu button (looks like three -) and choose Options.
Select the General panel.
In the Startup box under Home Page: click Restore to Default.
Close the about:preferences page. Any changes you've made will automatically be saved.

3. Under Options, General, go down to tabs and uncheck open windows in a new tab instead.

4. Have you tried resetting the home page?

Have you tried resetting the home page? Firefox might be set to open multiple tabs. Try it!

Click the three bars thingie on the top right of Firefox.

Choose the "options" icon.

Make sure to select "General" on the left menu.

Set the "When Firefox Starts" option to "blank page."
