While incognito, no failure to log or javascript debug.

Done two days of googling but nothing that pinpoints solution.
Some refers to legacy_browsers (tried it, didn't help) http://www.roundcubeforum.net/index.php?topic=22278.0
Some hint it could be CSRF (whatever it is..) https://github.com/alexandregz/twofactor_gauthenticator/issues/24
Maybe closest is this closed thread: https://support.mayfirst.org/ticket/10769

Anyway, so far no solution.
Apparently something was changed as this came up after some of the last apt-get update, unfortunately not sure which one.

SOLVED. It was Chrome extension called AS Magic Player. Removing it and it works again.

Similar behaviour with:
-move email
-compose new email and try to send (skips spelling check), never sends
-does not refresh automatically new emails to the list
-if delete one, it disappears from list but not from folder counter. If click to another folder and click back to this folder, deleted email shows up like it never deleted
-double click email to view it, click Show Headers => opens empty textbox and gives failure to log&javascript

There may be other but I'm a bit hesitant to go and test 'em all while this is broken.

Hints are appreciated

If its working fine with incognito mode my first though is some sort of conflict with Chrome extensions.
