Firefox does not display banners in youtube videos or flash games and instead shows yellow fields with a red font. Everything works in MS Edge. Flash Player is correctly installed.

Make sure you are not blocking content.

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Hi Fred, Thanks for the help, as I got back today the problem was gone, Firefox works like normal again. I suspect it had something to do with a recent Windows update, after that Firefox and Thunderbird had bugs.
