Hello,

In Firefox 23, as part of an effort to simplify the Firefox options set and facilitate future improvements to Firefox, the option to hide the tab bar was removed.

Fortunately, this can easily be resolved if you desire the keep tabs hidden. You can install "Hide tab bar with one tab", an extension hosted on Mozilla's add-ons site, which will restore the ability to hide the tab bar.

Thank you and I hope this helps!

That is the way it was before yesterday. Now, that miserable search tab is always present, so there are a minimum of two tabs. I have to get rid of the search tab.

Oh, a search tab. You must have a malware addon.

Delete any programs from the control panel that were recently installed, use the search reset tool and delete a possible user.js file.

Use a compressed image type like PNG or JPG to save the screenshot.

I can get jpg. How do I attach it to the reply?

I can describe it. It is to the right of the conventional tabs. At the far left of the tab is an icon that looks like a four blade propeller, with no hub. The blades are green,red, orange and blue. Next to that is a tiny arrow which brings up a drop down menu with 6 items like eBay etc. Next to that is a reddish orange button which says "search" in white letters.

I forgot next to the drop down arrow it says "Search Here".

found the button

Do you have the "Default Tab" extension installed?

Here's the screen shot.

Also, I tried Malwarebytes.  It acted the same as MSSE.  The malwarebytes process hogs the whole computer.  When I tried to download all of the latest definitions, the computer froze solid.  Required a hard boot.  I then uninstalled Malwarebytes which took a VERY long time, probably because the MSSE malware process was hogging the computer.  Whatever this thing is, it doesn't go down easily.

Try less of a "memory hog" in adwcleaner.

default tab extension is installed.

Can you uninstall the "Default Tab" extension as that is considered malware and is causing this search bar?
Otherwise just disable this extension.

Thanks so much. Microsoft Security Essentials failed to detect it and let it disable my computer. I think it must have got on my computer with an update to my Firefox. I am extremely disappointed with Firefox because of this and the fact that I cannot hide the tab line. I know I can fool around with a plug in to hide the tab line, but it is more time. Taking away the ability to hide something is just plain STUPID. I you want to give me a feature I never use, fine, but please do not take two lines of my screen for something I never use.

Maybe you shouldnt of had installed malware, that was your problem.
