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.

Az új 82.0 firefoxal nem működik sajnos :(

It stopped working October 30, 2020. I hate the new look.

Dont bother downloading, it does not work

It was working fine for a while .
Shut down P.C. for 4 days , came back from my hunt and when turned P.C. back on it says I'm in the Old version but its on the New and it wont allow it to go back to the old .

Hi Matt, I was almost finished with my business when the old FB stopped working. It just goes right back to the new layout. Reload does not work.

Stopped working today 10/20/2020

Stopped working on my firefox, why??? help please

I put one star to get your attention, it is no longer working on Firefox for Mac. When I enable it it says browser is not supported and puts everything in the old mobile layout. When I turn it off it widens it, but when I restart it goes back to the new crappy layout. Before it was great!!!

YOU SAVED MY LIFE !!!!!!!!!!!!!!!!!!!!!!!!
