Thanks!

It was/is checked under Safari, Select Unwanted Data. I even have it checked under Timer Options. Under Safari, Select Unwanted Data, each item can be individually removed using "Remove Now" or collectively for the ones checked, "Remove All Unwanted Data." When I select "Remove All Unwanted Data" it removes for everything except the tracking cookies, which is checked. When I select "Remove Now" which is to the right of "Tracking Cookies," it does not remove them, it does not grey out like all the other Remove Now items in the list. It remains black and selectable. I selected it several times and it never greys out and the tracking cookies never delete.

Additionally, when in the Cookies tab as opposed to the Removal tab, when I select "Remove Tracking Cookies" it never greys out. I select it repeatedly for Safari and it remains black, rather than greyed out showing that the tracking cookies have been removed.

I just looked at the link. I did that already, prior to sending this query. Cookie shows as having Full Disk Access. This issue persists even with Cookie having Full Disk Access.

Yes. I am on Mojave. Will read info at link you've posted.

Tracking cookies won't delete under the Safari browser tab. When I select "Remove Tracking Cookies" they are removed for all but Safari. Any thoughts?

Been searching for the last hour and can't find any information on the Advanced setting, Never remove Browser Extensions.

I want to know how this works. Are there settings that need to be kept for items such as Firefox extensions? If I tweak a setting in the extension's settings, will it go away if i let those cookies (databases specifically) get deleted? Or are the Databases for something other than the settings on some extensions?

I'm not clear on what happens if I uncheck that box and how it will affect, if at all, my extension's settings.

Not a problem.

It continues to quit on its own.

Yes I did. Let me make sure it's opening the right one. I didn't delete the other one.

Ok. I've made sure it is now opening the correct one. I deleted the old one from my system to make sure. I'll keep you posted.

It just quit again about 3 minutes ago on its own. I did not interact with it all day.

This is the corresponding crash report.
