If you are getting an error immediately after opening popup, have you followed the Configure browsers documentation section?

I think this is the same issue as #82. Ubuntu is now supplying Firefox as a snap package and browserpass no longer works.

Exact steps to reproduce the problem

1. Click on the browserpass icon in Firefox

2. See an error message: "Error: Error: Attempt to postMessage on disconnected port"

What should happen?

Browserpass should work with Firefox.

What happened instead?

Browserpass doesn't work with the snap version of Firefox.

I agree that the issue is indeed very similar, hopefully solving one would solve the other 🙂

The snap package is now the default in Ubuntu 22.04 so it just started failing for me after upgrading my Ubuntu to the newest LTS. Please let me know if I can do anything to provide useful information.

Please see the linked Chromium thread, you'll find some info about what people tried and what is missing to get this issue solved.

I actually remember that thread from 2019 😅 But to be honest I don't know how to help by looking at that issue. I'm neither a Go nor a Snap developer, so the best I can do right now is provide logs and that kind of information and try already suggested workarounds.

For now I reverted to deb-style Firefox by following these instructions. I can confirm that browserpass works again :)

I did not try this myself yet but for the curious, there is a call for testing with respect to native messaging support in the Firefox snap.

And now I did test it. Running 22.04.1, default Gnome/Wayland:

apt remove firefox
mv ~/.mozilla some-backup # might not be necessary

# remove all the apt overriding
rm /etc/apt/apt.conf.d/51unattended-upgrades-firefox
rm /etc/apt/sources.list.d/mozillateam-ubuntu-ppa-jammy.list
sudo rm /etc/apt/preferences.d/mozilla-firefox

# install beta snap and add native messaging app
snap install firefox --beta
cd /usr/lib/browserpass && make hosts-firefox-user

After starting and installing browserpass from firefox addons I had to allow calling the native messaging app once. And here we go:

After installing snap firefox beta, if you don't get a popup dialog asking for native messaging permissions for browserpass, run this command after closing firefox:

flatpak permission-set webextensions com.github.browserpass.native snap.firefox yes

Do I understand correctly that this issue is now solved and can be closed? 🎉

Sorry for the delay in replying. Yes, this is working for me now. Thanks!
