Very nice. Thank you. It works again with firefox 82 and facebook.

worked perfect but of today. 21.20.2020 it does not work anymore, can we expect a fix?

FOR EVERYONE. IF THIS ADD-ON DOESN'T WORK ANYMORE UNINSTALL IT AND THEN DOWNLOAD IT AGAIN, SO THE PROBLEM WILL BE FIXED

EDIT: Thank you so much for all the hard work to get it to work again. It is not an easy thing to do. I hope you find a way to make it work for everyone again and for those whom it doesn't work for (yet) don't be mean with one star reviews when you clearly state you're working on solving the issue. Facebook itself is the problem here people! Not Matt who is doing everything to make it work again!

It was soooo good when it worked.. But yesterday evening it went back to new layout and nothing I do helps to bring back the old one.
There was a Firefox update, but I also use Chrome and that one has the same problem. I hope it gets fixed soon because I so hate the new layout on fb... can't find anything...

As much as Facebook want to force their terrible new interface Old Layout helps longtime users like me keep the original look.

very useful extension, but it doesn't work now. Hope someone can fix it

Great!!!

This is informative, helpful and in good faith with Classic Facebook.
