Firefox: How to stop a new tab link in progress?

[ComicsLover]

I've been wondering this for quite a long time now.

You have a lot of opened tabs you want to keep because it would be a pain to find all the pages again for each tab.
You right click and select Open Link In New Tab.
The page starts to download to the tab, but is stopped because it's asking if you want to okay or decline the site's cookies.
You realize you don't want to open that site after all and try to cancel the tab.
You can't.  It keeps asking for the decline or  okay of cookies until the whole site is on the tab anyway.
Only other way is to force close Firefox, reopen all previous tabs...and lickety-split close that last offending tab before it gets too far in the downloading process.

My question:  Is there a way I have not found to get just that one tab to close before the site fully downloads?  (Or is it moot by that point as the site is already fully downloaded anyway?)

It may be too late by the time you see the message about the site cookies but the way to stop a page loading is to tap Esc. 

Unless you've customized the Navigation Bar, there should also be a Stop icon (X, Red when page loading) next to Refresh.  The standard location is to the right of the location/address bar.

Holy moley!  You mean the ESC key actually does something after all?
(I'd come to the conclusion after years of computer use that it was either for decoration, a finger exercising tool, or somebody playing a prank on purchasers.)

Thanks.  Darn cookie messages come up almost instantly, so I guess I'm stuck either okaying a gazillion site cookies for a page or quiting Firefox and restarting.

Maybe I'll try switching browsers for any links I'm not sure I really want to see.  Then when I quite the browser I won't lose everything.
