There wasn't really anything remotely deleted here. You just reloaded the page
and the script was not sent again, right?
What's far more worrying however, is that the code you put on Pastebin doesn't
look like it belongs on this webpage. To me it looks like some code to track
your geolocation. Either the website itself or the Tor exit node (or perhaps
even some other attacker in the middle) tried to inject some code here, I
guess. When you restarted Tor Browser, you probably got a new curcuit for the
site and thus a new exit node.
Perhaps it's a good idea, to not disable the add-ons which are supposed to
You don't just by a chance know, which exit node you used for that site when
