I try to log in into sync on fresh new laptop after downloading browser, so it has no extensions. It is stuck on login page with 'working' on login endlessly. It shows following error in the console: <pre><nowiki>*********** Working… instrument.js:109:42 v instrument.js:109 error logger.js:69 captureError error-utils.js:63 logError base.js:786 O base.js:80 Underscore 2 _workingTimeout notify_delayed_request.js:21 i timer-mixin.js:29 s helpers.js:74 *********** Response not received for: fxaccounts:can_link_account instrument.js:109:42 v instrument.js:109 error logger.js:72 timeout duplex.js:35 s helpers.js:74 *********** </nowiki></pre><br> refreshing and reinstalling did no good, and older pc on the same network logs in to sync perfectly.
