Tor browser has been automatically removed and the launcher reinstalled it randomly

[BarbzYHOOL]

Hello, Today, I launched Tor browser as usual and torbrowser-launcher started and installed it like it was the first time I also lost my bookmarks

it's like it has been deleted

So:

1. why? I checked Apt history, i didn't do anything
2. Where does torbrowser-launcher install tor?

thanks
