This seems unnecessary and can be annoying, especially when pasting values into multiple form fields. Reproducible: Always Steps to Reproduce: 1. Visit a page with a text input 2. Enter some text into the input 3. Copy that text to the clipboard 4. Submit the form 5. Re-visit the page from (1) 6. Paste from the clipboard into the form field Actual Results: The auto-complete list appears, suggesting the value just pasted in. Expected Results: Auto-complete should not appear. I can see two possible ways of addressing this issue: either not invoking auto-complete for pasted text at all, or never suggesting the exact value already in the form field. See also Bug 462690 which is related but not (IMO) a true duplicate.

This is not a duplicate of Bug 262206, although it is closely related. Fixing that bug would render this bug moot, but it's not the same thing. Especially given that 262206 is WONTFIX, I think it makes sense to handle pasted content differently from manually entered.
