Firefox and Rumble Chats - FF doesnt copy name of chatter like it used to.

I prefer Firefox over all other browsers I've tried About a year ago, I think, '''after an update''' I couldnt copy a chat into LibreWriter that included the name of the chatter. Disappointed, I found Brave browser that does copy all within the chat window. The thing is is Brave is unreliable, and often the chat locks up after an couple hours unless it is regularly checked -I stick with Firefox for my involvement, using Brave to record only because it lags while typing, sometimes so badly a whole sentence can be typed before it appears on screen. Can you restore the code that allowed the name of the chatter in Rumble chats to be copied like Firefox used to? It would be much appreciated. Thank you, Biff
