Hi,

I've reproduced the issue described above on Firefox Release v.62.0 Build ID: 20180830143136.
    
I've also tried on the latest Firefox Release version 63.0 Build ID:20181018182531, on Ubuntu 16.04 and Win10 x64, but couldn't reproduce the issue. In the newest Release the Content Blocking section has changed, as such following your steps don't reproduce the issue. 

Could you also update to the latest version of Firefox and confirm that the issue is not present anymore?
