I'm having problems with Firefox (v70.0 for Mac) not allowing me to copy text or links after a computer crash and restart. Does anyone else have this problem? The computer has been crashing about every 3 days, and after each restart I will run Firefox only to find that it will no longer allow copying of text or links. The Copy menu item in the Edit menu becomes greyed out and no selected text is copied. I can correct this by quitting Firefox and restarting; then the Copy menu item is available again and I can copy web page text. All other programs continue to provide copy functions even as Firefox is not able to copy. One other point. When I run Firefox after a computer crash it will bring up a page, then close it, then reopen the page. That is my reminder that I won't be able to copy items without first quitting. On the second time I run Firefox it only opens the initial page once.
