I know the meaning of the message , eg. that there were problem with the add on installation. I do not want the add on to be installed. What I want is to get rid of the message Firefox displaying each time i refresh the page that is trying to install the add on. Is it possible to prevent the message from pop up each time the site is asking Firefox to install the add on ? Any suitable about:config settings ?

How about Warn me when websites try to install extensions in Options > Security?

You need an allow exception to avoid getting a warning when you install an extension.

You can inspect and manage permissions for the domain in the currently selected tab via these steps:

  • click the "Site Identity Button" (globe/padlock) at the left end of the location/address bar
  • click the arrow to expand the security message
  • click "More Information" to open "Tools > Page Info"
  • click "Permissions" to inspect and modify permissions
  • click "Security" to inspect and modify cookies and passwords in a standalone window

Go to the Permissions tab (Tools > Page Info > Permissions) to check the permissions for the domain in the currently selected tab.
