Why does PhpStorm 2020 open a new browser window (firefox) when debugging and reset the user session?

Question

ubuntu

Installed a new PhpStorm 2020, set up Xdebug. Works.
However, there are 2 problems: when you click on the Debug button, a new tab in the open browser used to open, and the user's session was saved (he remained logged in).
Now, not only does the browser open in a new window when debugging, the user session is terminated and he becomes unlogged. (this is like opening the browser in incognito mode).

Someone faced? In which direction to dig? Browser problem? Or in a storm?

PhpStorm 2020.2, Firefox 80, Ubuntu 20

Answer 1

In general, I figured it out myself.
Run / Edit configurations - where the browser settings are, go to Firefox, select custom path and add /usr/bin/firefox -new-tab to the path , and in the list of browsers opposite firefox, select edit, and select the default-release
profile PS session was terminated, because the browser was launched under a different profile.
