Don't block popups
Trying to edit a draft in Zimbra, but Vivaldi blocks popups. Oops! Browser is blocking popups. I have looked in the settings and cannot find where to turn this blocking off. Also. When creating a new email, I do no want that window as a tab, but open as a stand alone window. It was possible when I used Opera.
The missing popup window is a known issue in Vivaldi.
You can unblock popups, currently a Vivaldi setting is missing.
But you can:
1. open chrome://settings/content/
2. and set your exceptions for popups
I found the settings for blocking popups. At the end of address bar there is an icon with a square. Here there is possible to allow all popups for a given site.
However even setting Always Allow it does not work, but if it is a known issue hopefully it will be fixed soon.
