Firefox Overwrites First Tab
 

I've been having this problem with Firefox. Whenever I start a new page, and open a new tab, instead of opening as a seperate tab it will overwrite the first page I was on. The next tab I open after that will open seperately as normal, but this is pretty annoying. Any ideas how to fix it?

How, exactly, are you doing this? If you're middle-clicking or control-clicking on single links, this should not happen, but if you're clicking on (for example) a folder of bookmarks to open multiple pages, this is perfectly normal.

It basically does it no matter what I click, whether it's a link to another site or a simple picture. No idea how to fix this, but even after reinstalling Firefox after the reboot, it still happens.
