I just discovered that I can't launch FF ver 87.0 in a separate folder which I had made for FF. If I launch it in the original ''''DefaultBox' '''folder,it opens sandboxed okay. I made two Sandboxie folders so I wouldn't have to close my browser '''and''' my email if my browser was high- jacked on a webpage,which has happened now and then. The question remains though,why can't I launch FF in the special Sandboxie folder? Oh well,I am just happy I can run FF sandboxed again. Sorry for the bother.
