Adding torrents opens multiple Tribler browser tabs

[teddyrogers]

Tribler 8.0.7, if Tribler is open in a browser tab and I click on a .torrent file a new browser tab is opened with another Tribler page.

Is it possible to prevent this behaviour, stop multiple tabs and Tribler pages from opening if one already exists?

I think there's an elegant way to avoid multiple tabs by adding the number of existing sessions to the initial core connection message, here:

tribler/src/tribler/core/restapi/events_endpoint.py

Line 112 in 5087eba

"kwargs": {"public_key": self.public_key or "", "version": v}

I'll give it a shot.

UPDATE: Above is not a good idea. The events endpoint streams in bytes, it's not a good solution to get just a single "alive" message (without a streaming protocol).

Could you do this through JavaScript using localStorage (or even a cookie) and checking on page load/ unload with a session key/ hash?

We could technically use that information. However, the solution of #8442 avoids talking to the GUI altogether, which is faster.
