The button used to work for me a couple of years ago but now it doesn't work properly. I can only find a few of my facebook friends on Duo using the button. It's really annoying that it doesn't work!

Yes, I find this as well to be true.

I was about to search for friends on Facebook when I realized that Duolingo was going to send out an invite to everyone.

Well, I didn't want to do that as some of the "friends" in my Facebook page are business contacts where such invitation would be inappropriate. There was a box to "uncheck" so I did, believing that I would then be able to select who to send an invitation to...

...but it has never come back, even after clearing cookies and my cache. I am on a Win10 64X system using Google Chrome.

Same problem

Doesn't work for me either! MacOS High Sierra + Chrome/Safari

I'm on Windows 8, Chrome V. 39.0.2171.95.

Same here. W10, Chrome and Edge

it does not work for me on my windows/chrome either

Doesnt work for me either

This feature does not work for me either.

Same symptom: click "Find Friends on Facebook" and nothing happens.

I am running Chrome Version 63.0.3239.132 (Official Build) (64-bit) and Mac OS Sierra 10.12.6.

It doesn't work for me either. I have chrome. I made a post about this but I can't find it! But I see people have been having this problem for years. So.... I'm guessing this will never be fixed???

Also, doesn't work for me. Its there, but I can't click it.

Same stands for me

i can't use it either, using mac 10.10.5 safari :/

I'm running the latest version of Windows 10 Home, and using Firefox Quantum version 60.0.2 (64-bit)...that's the latest version of Firefox Quantum as of my writing this comment.

I have the exact same issue as everyone else seems to be having: I go to click on the "Find friends on Facebook" button, but when I click on it, nothing happens.

Judging by the amount of people who've been having this problem for a long time, I think it's pretty safe to assume that Duolingo doesn't give a crap about fixing or maintaining their website - at least, not as far as Facebook integration is concerned.

That's a bad way to do business, if you ask me. Shameful, really.

It has happened to me today as well. All the circles have changed and most of them have gone all the way to 'zero' as well as the search button does not work well. It doesn't seem to get find any results.
