No, I don't have any extensions like that installed, and the feature just showed up for me.
Indeed, we added a "Send Page/Tab/Link to device" menu item to the contextual menu.

Is it new to 52? I hadn't seen a menu until today and really wanted to have that feature.
Yes this UI is new, there was an unofficial add-on [0] before that did something similar.
During my internship this summer we also added Push capabilities to decrease the time it takes to send a tab to another device (it used to be in the order of minutes).

It appears you don't have to have tab sync on for it to work. Mine does take a very long time to be received. Definitely a great feature, I don't want full tab sync just this.

I don't have that addon installed and am able to send links to my other devices.
EDIT asking because it's been this way for a long time, see https://wiki.mozilla.org/Services/PushTabToDevice#Desktop_Im... which says "Currently, push-tab-to-device on desktop must be used through an addon: [send-tab-to-device]"
