Is there a way to grant a website full clipboard permission?

I frequently use google image translate by taking screenshots and pasting them in the website. On chrome, I could grant it access to the clipboard on the first screenshot then not worry about it anymore. On firefox however, pressing ctrl + v first opens a context menu where I then have to click "paste" (or press p) '''every single time'''. It's getting annoying to have to go through this extra step. Is there a setting or add-on that would allow me to give a website full clipboard permissions like other browsers?
