I downloaded the new VERSION of Firefox, and now a new tab opens, that I cant get rid of. It's a Linked In JOBS Insider tab, and it opens vertically to the left. It has an X to the right that I can click and easily close, but when I OPEN CRAIGSLIST, or other job hunting searches, it opens back up again. I've tried to click on Toolbar's, customize, to try and get rid of. I've tried to click on options, and get rid of there also.
Can someone please try to help me?
