Ctl-T nor the File-Open Tab are working any more. Did you kill this?
I am a heavy user of the Ctl-T function, which opens a new tab on my existing Firefox screen. It is no longer working. Also, when I select File - New Tab, that doesn't open a new tab either. The File - New Window option works, but I don't want to have multiple Firefoxes open on my system. I've used this feature forever, and in the last couple of weeks (didn't notice the exact time), it stopped working. Did you change something?

Try uninstalling the Ask toolbar and it should work again. There is a compatibility issue with the Ask toolbar and the current version of Firefox.
