I thought he wanted to keep his ex from seeing his profile. Yup, Firefox' Adblock can selectively block out Images of her, but does not remove the Image Placeholder from the Row.
If she changes any Pic, then the newer added or replaced Image would have to be "adblocked" again.
It's a Band-Aid, best suited to filter out a few selected Users. If "over-done", ie. too many Users blocked, then the WebPage may go out of whack. It should only be used if seeing a specific Person(s) is causing undue Stress. To Filter out Dozens or even Hundreds of Users one is simply not interested in will cause Page loading Errors.
The best Way to do this is to right-click on all Thumbnail Images of any given Profile and "Adblock" them.
 | Thereafter they won't show on any Picture Row on any Page on Site. |
