Force pasting is something that is unfortunately required in many places, not just the browser. For example a Citrix session where the Citrix admin decided that pasting was a security risk and hence blocked it. Or some very poorly written apps.

For all of these I use an apple script that emulates typing one letter at a time, with a small delay because Citrix can't deal with typing which is too fast.

It's based on Force Paste: https://github.com/EugeneDae/Force-Paste

I invoke it with a shortcut (Alfred on macOS for example) and it's a life saver multiple times a day. Weirdly satisfying to watch happening =)
