I don’t quite get what changing the name would achieve in this scenario? I might be misunderstanding what you mean though. That being said, this was a suggested change 2 months ago within the community, so very unlikely to be any motivation behind it other than genuine change to clarify the feature. https://bugzilla.mozilla.org/show_bug.cgi?id=1924493

It’s less they removed the option, and moreso that they renamed it to Copy Clean Link. Functionally, it stayed the same. https://www.mozilla.org/en-US/firefox/135.0a1/releasenotes/
