Reproducible: Sometimes Steps to Reproduce: Write a really long message to a web forum in a very small textarea, and paste some quotes or URLs from other web pages to the end of your message. :-( Actual Results: blah blah blah blhttp://www.some.domain.org/ah blah blah blah Expected Results: blah blah blah blah blah blah blah http://www.some.domain.org/ This is compiled from CVS from yesterday morning, but I've been seeing this problem for a long time.

i find that th is happens regardless of amount of text; pasting seems to detect where cursor is the moment one pastes instead of honoring insertion point as indicated by caret. It's a dup, however, of bug 48786 "Middle click pasting in textfield inserts at wrong point within field" *** This bug has been marked as a duplicate of 48786 ***
