It's good now.I did "Clear saved session" like gold_finger said and it helps.And for the second issue I found the answer,thanks to rokytnji,at mozilla support.The reason was:
"This can happen if the website's server incorrectly specifies the Internet Media type of the file. It also can happen if the server assigns "Content-Disposition: attachment" to the file".
Thanks!
