Hi, I opened Firefox. I had left a few tabs open from the previous session. To my surprise when I opened the program this morning, it seemed to me that an advertisement's "new window" had hijacked the program. This "new window" does not allow me to go to the original window with all the tabs that I had been working on. My original window has also been reduced to the size of a small cookie and is like if I used exposé. It is hiding away, and when I have reached it, it does not allow me to work on it. Thank you, very kind regards, igmolinav.
