I noticed this about two years ago; show me that I’m not the only one who cares about this.
The strategy of a “detached window,” as some active forum members suggest as a long-term permanent solution, is fundamentally flawed.
I easily end up with five or more of these windows. These “detached windows” hide under the browser, and I only find them after several hours. I’d like to remind you that each detached window consumes memory just like any browser extension—50-100 MB. The Windows taskbar groups them together, and I don’t even notice them.
A “detached window” is a dead-end approach! Even if my suggestions were implemented, it would be better to have just one “detached window.” In that case, its state should switch to receiving the active tab’s address and automatically searching for the appropriate password.
This kind of behavior would be the most convenient.
