@challenger2010 Working fine. Needed Inverting but that was it.

@bytethis said in Issues using RetroPie forums with Mozilla Firefox:

@madmodder123 Better ad block software is ublock origin than Adblock Plus. Adblock got bought out and compromised. Conversation here : https://www.reddit.com/r/RetroPie/comments/7s7r4s/unable_to_get_playstation_bios_working/

ublock origin : https://en.wikipedia.org/wiki/UBlock_Origin

Ublock blocks more unwanted ads..popups..etc and 100% effective.

Apologize for going off topic in your thread.

Ah that seems to have been it, ublock origin is working fine for me now. Thanks for letting me know about adblock plus, I remember when they were on top, but I guess times change :/
Interesting though that it seems even though adblock plus was disabled for this website, it seemed to be causing the issue.

@mediamogul thanks.

I had firefox LD working with lr-mame 2016. The game is very slow but 100% working
