Many browsers do pre-fetching and caching of web pages for speed and performance optimization. But Mozilla Firefox has taken one step forward, it stealthily loads web pages when you hover over links. Yes! Unlike older versions of Firefox, more recent versions will make a request to a destination server just by hovering over a link.

How it works?
According to Mozilla Developer blog,
"nsISpeculativeConnect lets the networking layer begin setting up TCP and, if appropriate, SSL handshakes to save time when the connection is actually opened later."
In it pre-loads the web pages so that browsing would be easy and time-saving.
How to fix this?
1. Type "about:config" into the address bar (and you'll see a list of variables)
(The first time you look at "about:config", Firefox might ask you "Are you sure you know what you're doing?" Click "yes" and proceed.)
2. Copy-paste "network.http.speculative-parallel-limit" into the search bar at the top of that page and hit Return.
3. You'll now just have that one line on the page. Double-click it (or right-click on it and select "Modify")
4. A box pops up, change the value to 0, and hit OK.
