Brave Browser not Working Properly on Facebook

I had been using brave browser a few months and I can say it is the best alternative to the obnoxious Google Chrome. But I had a problem as I cannot send message on facebook as the message field is missing and I observed it that it is not blocking ads on facebook.

So I tested it on the mobile version of facebook, adblocker works normally but on the desktop version it is screwed.
