As of recently, I’m experiencing a recurring issue when running Thunderbird on Ubuntu, alongside Firefox. The problem arises specifically when clicking on a link in an email, particularly links from the Freshdesk Ticket System. After Thunderbird opens the link in Firefox, it appears to disrupt keyboard input in Firefox. For example, when attempting to add a newline in a Freshdesk ticket (by pressing Enter), new tabs are opened in Firefox instead. This issue immediately resolves either after closing Thunderbird. Could you provide any insights or suggestions on how to resolve this? It’s a consistent inconvenience in my workflow. Thank you for your assistance.
