Some problems with Firefox 68.0.1

Hello,
Since version 68.0.1 of Firefox, I have some problems with the Bitwarden extension.
Every time I visit a page that is well known to me, the Bitwarden web extension does not notify me of any login or password for that page. However, with another browser, they are well present.
In addition, Bitwarden is set to “never” in the locking options.
Every time I open the browser, I have to log in again.
In addition, I receive an email each time that a new device has connected with Bitwarden like: " Your Bitwarden account was just logged into from a new device.

You can deauthorize all devices that have access to your account from the web vault under Settings → My Account → Deauthorize Sessions."
I would like to point out that I am not in private swimming mode.
Have any of you ever faced this problem?
Thank you to all of you.
