Mac OS X 10.9.3, Firefox 30.0, updated today. Since then, all my copied texts somehow automatically get into "find on page" field. And some other behaviour, like that: I find some text on the page, for example "picture", and find the first one named "picture of me". Then I make it a link to downloadable picture and copy the text to put it in some other places down the page, while saving the text and the link. Then i push the "search down" button near the "find on page" field (where "picture" is written", and get to the place where I see another "picture of me" text, so i select it, and push cmd+V to paste the text with saved link, and, instead of that, the text replaces with the word "picture", which was in search field. And it has no link. So when i pushed the search down button, i automatically copied its content into clipboard. How the hell does it happen? I do not know about Windows, but it was not acting like that before, and only appeared after update on Mac. I need help to fix it! Thanks.
