Protecting cookies from “delete all cookies”.
My sister is having issues with issues using a cloud application and the cookies that it requires to save work settings. She needs to save cookies from session to session to preserve her configuration settings. Several browsers offer the feature to not delete cookies from a whitelist of sites when the browser closes. But due to bad internet connections, she needs to delete cookies from other sites while she is still working. The delete all cookies feature on the browsers she has tried will not honor her whitelist and deletes the cookies she is trying to preserve.
Any suggestions on which browser can a stronger whitelist feature that will preserve site specific cookies under all circumstances?
