hmm? see pic.

That is exactly what I'm looking for as depicted on picture. How do I get it. All I have is one block and it says:

Use recommended performance setting....and it's checked

I'm missing the 2nd block? Using FF 88.0.1 Was having problems with it and I did a refresh. I have no idea if the block was missing before the refresh or what? I'm experiencing extreme slowness and sometimes none response,

ok, try unchecking it.

mostimes, cycling the options will bring up new ones.

BINGO! You're the best. Another window opened and now I've got what I was looking for. Thank you for your help and now I'm going to give it a go and perhaps it will resolve other things. I'll click the block "Solved the problem" if it does.

You're welcome !
