My major GDocs/Sheets frustration is that doing a paste-without-formatting in Mac/Firefox silently fails. It works in Mac Chrome. No workaround that I can find. This is a regression from say, 2 years ago. I used to be psyched that I could use GDocs for work but now I hate that I'm forced to use it for work.
