Without the docker files, this cannot be reproduced by others. Can you share them?

The current beta version should forward "xdg-open" to the html5 client, which will display the link in the top bar, as per: https://xpra.org/trac/ticket/1862 I've just tried it again and it worked fine here. > I can add that xdg-open-forwarding for URLs was working in version > v2.4-r19581 I installed as beta in a container some week ago. > > There are two more bugs, that are present in both version of xpra and only > in HTML5 client. > > If I run "firefox https://xpra.org"; in the remote xterm terminal window, > Firefox launches regularly and the web page loads fine. > If I ctrl+click on a link, for example on About, the link is opened in the > same tab instead of a new one. > If I use the desktop client, the ctrl+click opens the link in a new tab as > expected.

Keyboard event support in Javascript is challenging: it isn't always possible to distinguish the numpad keys from other keys with the same label. At least not with all the different combinations of browsers, OS and input language settings. > Please, let me know if I can help any further in debugging these issues.
