With version 2023.9.1 instead of opening a small popup at the plugin icon, a new, small window will open in firefox to unlock the vault with shortcut Apple + Shift + L (insert last credentials to website login) .
But I will always get the bookmarks opened in this window and it is impossible to read login information, is it possible to change again?
I would suggest reporting this behavior as a GitHub Issue (official bug report), and tagging @cagonzalezcs.
OK, I will do so …
