Subject: bug#77415: Native Messaging in librewolf doesn't work
Date: Mon, 07 Apr 2025 16:07:58 +0200

Hi all,

Did you try the guix passff-icecat package?

$ guix shell icecat-minimal passff-icecat
then you start icecat, and it works

Same if you replace icecat-minimal with mullvadbrowser or torbrowser.

With librewolf there is an extra step due to a librewolf package bug:

$ guix shell librewolf passff-icecat
then
- you start librewolf
- [extra step] you go to about:addons and enable passff
- then it works

As to why it does not work with your non-guix extension, I imagine it's
because your native-messaging-hosts path is wrong?

Did you try either
- ~/.librewolf/native-messaging-hosts
- $ICECAT_SYSTEM_DIR/native-messaging-hosts

?

Cheers,
Clément Lassieur
