Hello. I am unable to add Mozilla Thunderbird (thunderbird.exe) to the custom list for Exploit Protection. It's not listed under the Default list, so I'm not sure why this is. It doesn't give me any errors or anything, it just doesn't show up in the list after adding. I am able to add other applications without issue.
Another question I had: is there any downside to enabling protection for all of the applications listed, even ones I don't have installed/don't use? And further, would it be wise to add basically every application I use regularly to the list?
