Okay, I'll try to help. - click settings>privacy&security and verify that 'accept cookies' is checked - click file>new >existing mail account - fill in requirements but DO NOT include password - be sure to include full email address - click the 'retest' button or 'done', whichever there is. - at this point, Google should show a pop-up for your credentials - after entering that, the screen should prompt with 'allow' button - click that and it should work.

Hello thanks for the attempt, the pop up comes i click and after comes server connection error. i deleted the password beforehand but seams thunderbird grabs something in « isp » database.
