[Desktop] Allow users to add site exceptions for data that is cleared "on exit"

Description

As it is now, any data type that is checked in the Clear browsing data --> [On exit] will have all data of that type removed upon closing the browser. While this is the intended function, we should implement a function similar to what Microsoft Edge does, where site exceptions can be added to a “Do not clear” list. Data on this list is ignored when the browser runs “clear on exit”:

This would help users maintain login data for sites they regularly visit and not have to re-authenticate every time data is erased. Additionally, this helps with support, since clearing browsing data often resolves issues with bad cache data – having the ability to suggest users do this, but without sacrificing specific data they know they want would be very useful and appreciated by users

This would really help a lot of people achieve better security, I’m sure more people would use the delete cookies on exit feature if you were able to add exceptions

So, I followed the advice to set up a new profile to test this and you all are absolutely right. It is a feature.

If I set Clear cookies and site data when you close all windows to on and add sites to Sites that can always use cookies those will not be deleted.

My problem came from setting Clear browsing data -> On exit -> Cookies and other site data, that’s the one which isn’t overwritten by the site exceptions. Thank you everyone!
