Se esegui Tor Browser e un altro browser allo stesso tempo, ciò non influirà sulle prestazioni di Tor o sulle proprietà della privacy.

However, be aware that when using Tor and another browser at the same time, your Tor activity could be linked to your non-Tor (real) IP from the other browser, simply by moving your mouse from one browser into the other.

Or you may simply forget and accidentally use that non-private browser to do something that you intended to do in Tor Browser instead.
