Make a PIN (hairpin) !
I have shown only one scenario. I see this every time I set up Bitwarden in a new browser, i.e. I am guaranteed to open its settings 2 times. I know this is his problem, and every time I try to guess the sequence of clicks so that the window does not close 2 times. Such a game, thank you.
This shows that the “no X-button” strategy chosen by Bitwarden does not work.
In my opinion, half of the forum here is devoted to this problem - how to fix the window from closing. The goal of Bitwarden - convenience when closing the window - deprived us of 1 click. Thank you. But you also added its HUGE problems due to the inability to copy a sequence of 2 lines of login and password.
I have shown in this picture a situation where you can get small problems without even reaching the password page. Bitwarden closes after one question from the Browser.
There is a well-known expression “Shoot yourself in the foot.” This situation accurately reflects it. The Russians still have one expression “They wanted the best, but it turned out as always” 
That is, I just won’t physically help you get to 2 daws in the settings. That is, I always have to log in 2 times to my favorite program
Here is my old, slightly delayed video (bug-report).
I have already had several posts with pictures on this topic. It’s been about 2 years now. Besides me, dozens and hundreds of users on this forum are asking for this pin. Tens and hundreds of thousands more users are simply silent outside the forum.
