When I bring up he Filtering Log and do a Reload or Refresh of the page, the AGE icon turns from blue to gray. From this point on all sites when clicking on the now gray AGE icon says 'AdGuard can not run on this domain.' I must restart Fx for this to go away but will return when I reload a page again. **** Problem also happens without reloading or refreshing. I notice when I go to site that has been filtered the entries take forever to display. If I get out out the Filtering log during the time entries are being displayed I get the gray icon. Seems that two or more entries have to be displayed in order for this to happen.
