PassBrow no longer works with Vivaldi.
Vivaldi has a different way of manipulating the tabs, making using PassBrow unusable, there are options in the settings where you can hide the tabs and the address bar so that they are not displayed when PassBrow closes its windows and displays the screen of login, but in a very simple way the manipulation of the browser is available, because Vivaldi does not use the type of window "popup", still giving the option for the user to open the popups as a tab. For these and other reasons that caused numerous bugs, in addition to the low number of PassBrow users with Vivaldi, the support and development of the extension for this browser was discontinued, it will continue to appear and receive updates because the browser uses the Chrome Web Store and there is no option to disable which browsers can use the extension. So use at your own risk. To users of this browser, we apologize.
