I came to report this bug but found it is already here. I am on linux (Pop!_OS 22.04 LTS) and am using Thunderbird 102.2.2, although this was also present in version 91 (I only upgraded recently).
I have Thunderbird set to use the system PDF application (in this case Evince) for reading PDF files, which works perfectly for reading messages sent to me. However, when I attach a PDF document to an email and try to open it to check something, it only gives me the option for Firefox. Fortunately, Firefox can display PDF files but it is not the behaviour I expected.Thanks for digging into it. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to thunderbird in Ubuntu. https://bugs.launchpad.net/bugs/1981163 Title: [upstream] In Compose window, if a PDf is joined and clicked to open, Thunderbird launches Firefox instead of Evince Status in Mozilla Thunderbird: In Progress Status in thunderbird package in Ubuntu: Confirmed Bug description: In Thunderbird on Ubuntu Gnome, I set Evince as default program to open pdf files from Thunderbird. In received messages, and those saved on "Sent" folder, it works perfectly. But in the "Compose" window: if I add a pdf file to the message, and double-click on it to open and verify it, Thunderbird always uses Firefox to show it. In case Firefox is not installed (has been removed), I have an error message telling there is not associated application for pdf files and to go to Preferences - where Evince is already and still defined as default. It happens since many months and bug is still present in Thunderbird 102 / Ubuntu 22.10 beta. It's not the same as bug 234349 as here, it's not an URL file but directly a pdf joined in a mail.
