Open in external app not working
"Open in external app" by pixelweben.de (installed from Google Store) doesn't work in Vivaldi snapshot 1.3.501.6 on Windows 7 (x86). After following the developer's instructions and installing his additional helper app to support the extension, the options do show up, but the field for entering an external application is greyed out, and the button to browse the file system for an application is disabled, as well. That's the most essential part of the extension. I can only enter a name for the app and its parameters, which is useless. I've e-mailed the author, but with no response. Is there a setting in Vivaldi that I'm overlooking and that might be blocking the extension?
