uuf3, 
when did you just start using version 3?
it gets mail OK if you don't switch to Firefox?
what antivirus program do you run?

I don't know why I'm on the "CC" list, but....

> if open web page of mail service
> mails will be in inbox but wont received by tbird

Do you know if the messages were:
1) actually downloaded from the server by TBird but are not in the "Inbox";
2) actually downloaded by TBird, are in the Inbox, but are not displayed; or,
3) were not downloaded by TBird. 

> so if not know how, this will cause critical (lose data) severity for some people

Since the messages are actually still on the server, no data was actually "lost" (although it may appear that way to the user).  If you "Get Mail" again, do the missing messages get downloaded ?

Try to repeat your experience, and gather the following:
1) Contents of "Inbox" before the "Get Mail" (for file location, see:
     http://kb.mozillazine.org/Profile_folder_-_Thunderbird
2) Contents of "popstate.dat" (the article noted above says this is "in Mail", but it's actually 
     in the 'servername' folder/directory in the "Mail" folder/directory)
3) Protocol trace; see https://wiki.mozilla.org/MailNews:Logging 
     (use "pop3" instead of the "imap" shown in the examples)
4) Contents of "Inbox" after "Get Mail"
5) Contents of "popstate.dat" after "Get Mail".

1. tbird down's heads of new mails
2. after selecting this mails and pressing link to download full contens of mail and than switch to ffox, this mail vanish from inbox
3. mails not showed in inbox (or any other folders) i don't know about downloaded mail or not

This would imply that 'popstate.dat' indicates they've already been downloaded (and may have already been downloaded, but are not being displayed for some reason).

> i must check content of popstate.dat after repeating problem for check, how
> mail downloads?

It is necessary to determine if 'popstate.dat' accurately reflects the state of the "Inbox" (and server) contents.  By having both "before problem" and "after problem" instances, we can determine what TB thinks those contents are, 

> and what i must see in .log?

If 'popstate.dat' indicates that a message was downloaded, but that message is not present in Inbox, the log will show whether TB actually _did_ download the mail (but somehow deleted it from the Inbox), or whether the mail was _not_ downloaded (but 'popstate.dat' was erroneously updated to indicate that it had been).
