Upon reevaluating the Firefox Extension, Proton Pass, it's clear that it holds true to its commitment of being an entirely private and secure password manager—it efficiently safeguards all your data, metadata included. However, the user interface could see enhancements, particularly in terms of detail management. As it stands at the time of this review, only a limited portion of the screen is available for editing all your details.

A key gripe for me is the inability to adjust your login email address—a restriction that Proton itself doesn't see as crucial, suggesting users subscribe to a new package with a different address if desired. This is puzzling, especially since I've managed to alter my email address on other secure platforms like sync.com, which also incorporate end-to-end encryption. Such experiences affirm that this feature, indeed, can be integrated, even within E2E encryption models' framework.

Despite these early developmental challenges and teething issues—commonplace for any new product—Proton Pass, barring the aforementioned points, proves itself to be an impressive offering.
