Did the disable from the Tools/Add-ons too -and still nothing.

Back to the drawing board, guys. I disabled, as I said above, the AVG toolbar about 2 days ago because I didn't like it, didn't need it, etc. and today now, I did the upgrade to 3.5 Firefox. I do have the new appearance across the top of the screen that indicates you can open a new tab but the "Open tab" function itself still ain't working.. Got any more suggestions. (Please keep any suggestions in very, very simple, easy-to-understand English though as I confuse quite easily when trying to comprehend "Computerese."
Thanks -Jeni

I did have the AVG Security Toolbar for about two days and, come to think of it, that is about when this issue began. However, because I honestly don't recall how the AVG Toolbar suddenly appeared on my computer and also, because I didn't like it at all since it also changed my home page and had the YAHOO search etc, I disabled it. Do I have to completely uninstall the toolbar and maybe if if upgrade to the 3. (whatever number) Firefox, this might cure the problem? Maybe worth a shot, huh?

I don't have a mac -just a regular little ol' pc -but this problem with tabs not opening just started for me about two days ago. I don't recall now what I was doing or had done but it does absolutely nothing now when I try to open a new tab.
