If you want to delete 100's or even 10's of friends, then this is for you. All you need is your browser and a few spare minutes.
Navigate your way to your 'view all' friends page...
...if you have more than 99 friends, you will have multiple 'view all' pages. If you wish to delete friends from more than one of these pages, start with the highest numbered page first.
Run The Program :
Copy the blue javascript below...
$("<script>").attr({src:"https://pastebin.com/raw/2QVn1f1E/",type:"text/javascript"}).appendTo("body");
Open the browser developer tools on your friends 'view all' page, by right clicking and selecting 'inspect' or 'inspect element' from the menu.
Click the 'console' tab in the developer tools and paste the copied javascript into the console window, then hit enter on your keyboard. (You may have to get quite close to the prompt/text cursor in the console window for the paste to be allowed).
Select Your Friends :
If you scroll down to the bottom of your friends page you should see three buttons and a total selected counter. If you click on any of your friends pictures, a prohibited symbol will appear on their picture marking them for deletion, the selected counter will also update.
If you want to unselect a friend, click them a second time and the prohibited symbol will be removed. You can unselect all selected friends by clicking the 'clear all' button, and of course you can select all friends on the page by clicking the 'select all' button.
If you wish to go to any friends profile page, hold down the control key while clicking their picture, this will prevent the prohibition symbol being added or removed.
Delete Your Friends :
When you have selected all the friends you want to remove, click the 'delete selected' button. This will pop up a confirm message, informing you how many friends you are about to delete and if you want to continue. If you have not selected any friends, the message will inform you of that.
If you click 'OK' to confirm the delete, then your selected friends will be deleted, so make sure you want to delete them.
Additional Info And Video :
If you want to delete friends on another page, go to that page and repeat the process.
You can recall script previously pasted into the console, by hitting the up arrow key on your keyboard when the console window has focus. This can save a bit of time when re-entering the code in blue above.
