I think this thing is glitchy. Every couple of days, it tells me a friend has unfriended me and then re-friended me shortly after. This has happened easily half a dozen times now - always the same friend. I asked this friend if they'd been unfriending and then re-friending me or messing with the settings on their account, and they say they have not. I believe her - I get along well with this person - but unfriend finder keeps popping up saying she's unfriended and then re-friended me.
Additionally, when clicking the 'help' button - nothing happens. It's completely unresponsive.

luwuk ok

Itu aja dulu, kalo sukses di tambah lg

Me dice siempre que he perdido todos mis amigos.

Good

It hasn't showed me antrhing so far. I guess thats a good thing lol

Not working

It does NOT show WHO unfriends you, it just shows the numbers of plus and minus friends. Nothing more.
Behind of it - coming hidden promo and adds of block adblock.

Good

good

不會用
臉書沒有出現Unfriend Finder的捷徑

I feel this is misleading. Each time I receive a notice that someone has unfriended me, I click to see who it is. Instead a message comes up promoting an app called, "BlockAdblocker". I disabled all ad blockers, & "unfriender" still did not do its job while still promoting "BlockAdblocker". So I hope this note is still published. If there is some answer to this app's problem, let us all know.
