I have Thunderbird 128.6.0esr (64-bit) installed as a Flatpack package on Fedora, running on Gnome / Wayland. Whenever I click a link in from an email from Github, that normally opens the browser, Thunderbird immediately freezes, and Gnome asks me if I want to kill Thunderbird. Waiting never works, and the link never opens. This is somewhat recent behavior. Links to other websites *do* open. I know how strange this sounds. How can I debug this?
