Does anyone have or know of anyone that has made a browser script that'll auto-remove the 404'd Favs (IE: the favs that link to a submission that the artist has since deleted)?

One thing I hate is seeing those little broken icons representing deleted pictures among my favorite list, and since the original faved object is gone with no link, info or anything to lead you to the original artist, it serves no purpose (aside from screaming out "HEY! I WAS DELETED! I don't know who I was deleted by, or what I was originally for, but I was deleted!")

And the reason I'm looking for a script is because manually searching my fav list is..well, tedious at best. Worse still is deleting the 404'd entries, since I'm kicked back to the first page of my list instead of to where I was, forcing me to copy-paste what my page was or click back to what page I was on.

For each 404'd entry.

And god help me if some artist mass deleted their whole account (or was banned), as that'll leave a metric tonne of 404s for me to clean up.

So, does anyone have anything that can help?
