Firefox opens two new windows when I click on a link

I am using Firefox browser on my MacBook Pro and I have noticed the following.

When I quit the Firefox app (no background activity), and I click on a link that I receive in an email (from my Mail app), then Firefox opens 2 windows. One is empty and the second leads to the desired link.

On the other hand, if I don't quit the Firefox app but simply close it (x symbol), then when I click on a link it open correctly in a single window.

I have experienced the Bug 1603956 referred to above.

Just to be clear, it is not the same as the initial question: "Firefox opens two new windows when I click on a link".

I am experiencing the two windows opening Firefox cold, from a link every time.

Bug 1603965 happens once in a while.
