Can only open one window at a time

Saver-upper

I am hoping someone can help me.I am not [STRIKE]very technical[/STRIKE] technically-minded at all,so don't know what has happened.
I am using Windows (8,maybe?).Normally,when I am browsing,I have several windows open at once: browsing a few threads on here at the same time,a couple of other sites,email is always open.Also normally,to open a new window,there is a "+" sign to the right of open tabs.Press this,and a new window opens for me to browse something else.However,tonight,the "+" has gone.So really,I can only open one window at a time.
I don't know what I have done,or how to fix it.Is anyone able to help?
Thank you.

Thank you for such a swift response,debitcardmayhem,though that doesn't do anything.

I presume you're using Internet Explorer?

Have you tried CTRL+T to open a new tab?

Also, try :

Press ALT to bring up the File Edit View bar.
Choose TOOLS and then INTERNET OPTIONS
In the GENERAL TAB choose settings
Select ENABLE TABBED BROWSING

Then close and re-open IE

Windows 8.x has two versions of Internet Explorer. One version is always full-screen and has the address bar at the bottom. I find it hard to navigate.
You'd also find that this

Press ALT to bring up the File Edit View bar.

won't work in the full screen version.

I'd use Alt-F4 to close it, then navigate to the old-style desktop and run Internet Explorer from there. Or another browser such as Chrome or Firefox.

Thank youPeter999 and Jivesinger.I am using Firefox,sorry should have said.

Ok. CTRL+T should still work.

To bring the new tab button back, try the instructions here :

Hey,pressing CTRL+T does work (thank you for the suggestionPeter999).
Might have to start doing that.But I wonder where my "+"s went? :think:

Saver-upper

Right,I've got it.Followed this from one of the links you provided,thank you Peter999.

Although the "+" did not appear when I hovered over the space to the right of last tab, I saw that the "+" was actually located at the very far right end of the menu taskbar. I simply went into "Customize" and moved it to the left end of the other apps that were lined up far to the right.
Then I got out of "Customize" and moved it to the last tab or maybe just to the right of it. It "jumped" into the desired position just to the right of the last tab. Success!!
