This is barely related, but I’ve recently discovered it using Firefox and just wanted to share my misery. If you’re not using Chrome with the Google Docs extension, then Google Sheets will REFUSE to let you copy and paste with a right click context menu. But you can just press the keyboard keys to do so, or use the menu options to do so.
Like…what? It works, but they refuse to let you do it with the context menu, despite including them in the context menu.
If you try, it pops up a window and tells you that you have to install their extension or pound sand.
