You are not having a delusion. There are plenty of times when I performed a google search and then went to several sites (in the same tab) drilling through. But wanting to backtrack found myself going not sequentially backward but straight back to the google search results.
I have no idea how Firefox (or should I really be accusing Mozilla's engine here) makes these decisions but it can, at times, be annoying.
The following advice won't solve the above issue but will take care of your open link in new window vs new tab issue.
In the Firefox menu select:
Edit--> Preferences--> in the pop-up GUI select "Tabs"
the tick-boxes and radio buttons are self-explanatory.
