All of a sudden, I can't create a new tab. The button is there but when I click on it nothing happens. Running Firefox 30.0
I only have the one tab open but still cannot create a new tab by clicking on the "Open a new tab" button. If I'm at a website and right-click, I can tell the page to open in a new tab. But I cannot get the new tab button to work. It will also not work with control-T

Let your employer know about that problem. Their developer is going to have to look into fixing that add-on.

Last Add-On disabled and then restart which resulted in being able to use the tab button was the DMACC Help Desk 10.31.0.526.
This is an add on from my employer (Des Moines Area Community College in Ankeny, Iowa). I've had this on my system forever and never had a problem with it before.
