Since yesterday, every time I try to use the link button (chain icon) and then I hit the button "Update" a pop-up hits me asking me "are you sure you want to navigate away from this page?". If I press OK I'm redirected away from my current Post to my Posts section and if I press Cancel, obviously, the link it's not made.
I know I can always get back to the old HTML, but I am lazy and I like using the chain button.
Ideas anyone? is this a bug only on my computer (firefox)?
