I had another extension that reverted FB to the old design, plus a lot of other customizations, but it stopped working to revert the design just the other day, even though most of the other functions still work just fine.

Well, I'm not the only one who finds the new design unusable, so I am very happy to have found this extension. Thanks so much. I thought I was going to have to give up Facebook.

Update Nov 18, 2020. Seems to have stopped working for me sometime in the past couple days. I uninstalled and reinstalled it, but It doesn't work for me anymore. I see a 5 star review from just 3 hours ago, so it's still working for someone I guess.

It does not work!

Не работает

Не работает...

Tried 4 times and nothing changes. Some are lucky I guess.

Does nothing for me on win 7 firefox 82. I don't believe it works for anyone. Prove it.

Doesn't work.

La 6.2 non funziona e anche rimuovendola e installando la 6.3 (?) continua ad installarmi la 6.2.

still stuck w/the new and unimproved

Unfortunately, it looks like the add on no longer converts to the old layout.

Oct 23 10:45 pm firefox 82, nothing occures when I press the button. Says 48 hours, but nothing changes.

Thanks for your efforts. FB seems to have foiled me. It will not revert to classic with your newest extension. I also use FBPurity, do you think it might clash with your extension?

Since the last update on 22nd Sept 2020, the old FB layout doesn't display anymore and does not work.

Stopped working, won't fix

Cannot Send Messages in FB Messenger with this Enabled. FB Messenger also does not change, but regular FB Pages do. Need to be able to send Messages.

Now I cannot get back into FB

As of 10/21/20 no longer working on Firefox despite reloading it. It's unfortunate because it was very helpful while it lasted. At least it's still working on Chrome.
