Remember to remove this application[1] from accessing your information after you're done.

[1] https://www.facebook.com/settings?tab=applications

You can do that, but I don't store the data anywhere using the app. You can comb through the source code, its an app made purely with JavaScript and EmberJS.

Even if you don't, it's a good idea to train users to remove apps that they're done with so that other less scrupulous developers don't have unnecessary access to their info.

Valid point, you're right.

Very nice. I recognise you can't auto unlike everything. On click can you shift the page a set number of vertical pixels to the next like button. Then I can just click to unlike in rapid succession.

Tweepi do this for mass unfollow, see the Flush tool interface here: http://tweepi.com/tools/flush#0

Good point! At first on my end it seemed like this was already kind of implemented since after every button click I scrolled my mouse wheel one tick down and the buttons aligned more or less (for a bit). This might be a good workaround!

Really? NICE. I'll try this out.

What's the reason you are asking for the email address permission?

As mentioned earlier, it's a default permission that Facebook gives access to.

This isn't the case any more: https://developers.facebook.com/docs/facebook-login/permissi...

You are explicitly requesting it. Take a look at the params you are passing to scope. I can see when clicking the sign in with facebook button in the URI you are requesting these permissions: scope=user_likes%2Cemail

I'm sure you are doing nothing malicious, but there's no way for us to be 100% sure you aren't doing something different on production.

Studies have also shown that you should only request those permissions that are needed, otherwise you lower conversions. So you might want to fix this right away.

This is no longer true for apps created after last years F8 conference (4/30/2014, Graph API v2.0,) and I believe the deprecation schedule ends in April.. Older apps will no longer get this by default.

IIRC it's by default when you ask for permissions.

I'm trying to make a script to uncheck them all, something like this :

    javascript:var x=document.getElementsByTagName("button");for(var i=0;i<x.length;i++) {if (x[i].type == 'submit') {x[i].click();}}; alert('Done');

Not working though...

Yeah, I tried the same thing. Facebook uses iFrames for rendering their Like buttons, so its impossible to automate the clicking of them. :/

Its possible using phantomjs but I am not sure I want to go through the effort.

Oh, that explains why!

Its unfortunate. :/ But, using this I found it wasn't too bad to scroll down and quickly unlike everything.

Nice! I did something pretty much exactly like this 3 years ago. If you are curious, the code is at Github:

http://unliker.prealfa.com/ https://github.com/adlpz/The-Unliker

Of course, please mind that it was years ago and maybe I wasn't, uhm, so _proficient_ back then ;).

Very nice! Don't worry, outside of EmberJS, I rarely write JavaScript so mine may not be as proficient either.

I do the opposite, I like random, suggested things. I like to poison their data with non-sense. Harmless to me, catastrophic for the creeps.

See, highschool me used to like random things but when you get it polluting your News Feed when all you care about is new music from indie artists, then that's when you want to start unliking things, haha.

Just mark them not to be visible in your feed.

If you only hide the stuff you don't care about, then you are poisoning their data with nonsense to a lesser extent.

I am working on an app that does a similar function but for 'friends'. Removing friends is very slow on desktop because of the thumbnails generated for all the profile pictures. The page refreshes often which further slows down the tedious task of deleting friendships.

Yeah, I was planning on creating something for friends as well, unfortunately the Graph API doesn't allow for programmatic deletion of friends, although it would be nice.

That's unfortunate (but good, I suppose) to know!

It seems it automatically goes to the next page (and scrolls about 1/3 down the page) once I scroll to the bottom? And there's no way to go back to the previous page?

Some usability issues, but overall a nice idea. I like the chronological sorting.

Yeah . . . I'm wondering how best to fix that. The problem with rendering iFrames is that once you hit 100, it gets CPU intensive and laggy, so I decided to delete older items under the assumption that the user was done with them. Thus, by limiting it to 50 items onscreen at once, it increases performance. Maybe pagination would have been better, I just didn't want to force users to click more than they had to.

I have 45 items. When I get to the bottom, it blanks all the items, and displays "finished loading items" twice. If I log out then log back in it displays my list of likes again .. until I scroll to the bottom.

Sounds like a very useful app. At least for those "liking hyperactive" FB users who have grown up and now are using FB to build their brand through the platform. Nice job guys!

Thanks! Heck, I remember back in the day when it was called 'Become a Fan' and not 'Like'. I was one of those hyperactive users out of boredom in high school, so I figured others would in a similar scenario.

It was also back when the "thing" you were a fan of wasn't a page that could post stuff to your feed. Now every single one of those "things" you were a fan of are pages that have admins/owners and can post stuff.

E.g. At some point you could populate your profile with favorite books, movies, artists, etc. You know, topersonalize. Well, now they're all pages and you like all of them.

Needs an unlike all option, you could just load all the unlike links and hit them all with jquery.trigger('click')?

Since the Like Button is an iFrame, that isn't possible, unfortunately.

If I scroll all the way the page links disappear and all I see is

"You have liked 56 pages.

Finished loading items!! Finished loading items!!"

I have same, initially it looks good and then this message without the ability to unlike things.

Great page though (when it works)!

I'm working on fixing that bug. This is my third EmberJS app, my first one with only EmberJS and no custom back-end, so I'm doing some hack-y things to get it to render more likes. Sorry about that~

Good idea.

One quick note to the authors (if you're reading), there's a typo on the info page:

s/need to you to/need you to/

Hey there, author of Page Unliker here. :) Thanks for catching that, I'll be sure to fix it!

Brilliant!

What about an "Unlike all" button?

I assume this uses the like widgets, so that's not possible. There's no Facebook permission for "ability to unlike pages".

Selenium it is, then.

Worked fine for me initially, but after refreshing the page, I get nothing

Try logging out and then logging back in. Its an annoying bug I'm trying to fix to no avail.

actually like this better, and works better and less buggy for me for some reason

Yes, same here. Yet, people downvote this suggestion…
