tab navigation doesn’t work in Google Chrome

in all cases you should be redirected to Wi-Fi login screen.

Dashlane window is not visible

solution

most likely Dashlane has already logged me out but login pop-up window is not shown - it doesn’t matter how many times I open and close application itself.

solution is to kill DashlaneAgent process - say, using htop or Activity Monitor. login pop-up window must appear the next time Dashlane is launched.
