Firefox keeps randomly switching windows.

[acuriousman]

Every time I open a new window link from a current window, the new window will pop up like normal.

But after I click on anything inside the new window, Firefox randomly switches to the previous window and I have to reclick the new window to get it back.

How do I fix this? I don't want it to keep switching back to the old window when I've already opened a new one.

I'm using the latest Firefox build 23.0.1, fresh install with Windows 7 64 bit
