Hello, Jamie! Thank you for mentioning this. We have made some improvements to memory management in Firefox but it appears there are still some issues we need to handle. If you have a support contract with Delinea I suggest opening a ticket with support so we can work with you to get any additional details about your usage of the extension to help our dev team.

Have you tried our new extension, "Delinea Credential Manager"? It is the recommended Delinea password manager extension going forward.
