Description Dimitris 2024-10-20 22:42:42 UTC

Thunderbird (currently 128.3.2-1.fc40) is not being invoked properly from Firefox (currently 131.0.3-1.fc40):

$ xdg-settings get default-url-scheme-handler mailto
org.mozilla.thunderbird.desktop

There's no override for Thunderbird under ~/.local/share/applications.

With TB already running, when attempting to open a mailto: url from a web page on Firefox, after a few seconds I get a TB error about TB "already running or use a different profile".

Reproducible: Always

Steps to Reproduce:
1. Start Firefox and Thunderbird.
2. In Firefox settings, under Applications, select "Thunderbird (default)".
3. Navigate to a page with a mailto: URL e.g. https://www.w3docs.com/snippets/html/how-to-create-mailto-links.html and click on a mailto: link.
4. After a few seconds, a popup appears with the message: "Thunderbird is already running, but is not responding. To use Thunderbird, you must first close the existing Thunderbird process, restart your device, or use a different profile."
5. However, from the command line, "xdg-open example" correctly gets a new email editor window from the running TB opened.
Actual Results:  
Invocation from Firefox seems to try to start a new TB process.

Expected Results:  
Should invoke TB such that the new email window is opened if TB is already running.

Not sure when this regressed as I don't click on mailto: often, but it used to work some time (months?) ago, potentially back in version 115.

Comment 1 Benji Wiebe 2024-10-30 16:04:21 UTC

I created a fresh VM of Fedora 40 KDE Plasma (using netinstall, so up-to-date), and dnf installed Firefox (version 131.0.3) and Thunderbird (128.3.3esr). Opening Thunderbird and Firefox, then clicking mailto: links in Firefox does indeed reproduce the bug.

However, if you download and install Firefox 132 from mozilla.org, extract it, and launch *that* copy of Firefox, mailto: links work as expected.
Just to confirm that this is a Fedora packaging issue. (unless it was fixed between FF 131 and 132??)

Comment 2 Dimitris 2024-10-31 03:03:55 UTC

Still reproduces with packaged version 132.0-2.fc41

Comment 3 Pierre Ossman 2024-11-29 06:19:05 UTC

Any progress with this? It's a rather large annoyance. :/
