Cookie Exceptions Keep Vanishing
i keep adding sites to my list of exceptions and mark them as Blocked, and usually when check again [as now] the list is empty. how do i stop this, why is FF losing my list? have i deleted something accidentally when zapping other items in my Manage Data list?
Note: Some software, like Advanced SystemCare with Surfing Protection, can protect files in the Firefox profile folder against changes. If you have such software then check the settings or uninstall this software.
Macs: Make sure you install Firefox properly and that you do not run Firefox from within the DMG (Disk Images) file. https://support.mozilla.org/en-US/kb/how-download-and-install-firefox-mac
