Suggestion: Add plasma-browser-integration package in Aurora

Aurora
1

KDE 6.4 now supports Plasma browser integration for Flatpak versions of Firefox and Chromium.
Here’s the link to KDE 6.4 Complete Changelog you can find it in Plasma Browser Integration section.

I think that plasma-browser-integration package could be pre-installed on Aurora in order to get this feature work :slight_smile:

It is included, but it doesn’t work by default!

I looked into it and asked around, and here’s what I found:

  1. The flatpak-integrator service used by plasma-browser-integrator “doesn’t like” symlinks. By default, $HOME points to the symlinked homedir at /home/user, which breaks the function that creates the files required for the integration to work. Details here, though I’m not sure if it should/will get fixed since…
  2. $HOME shouldn’t really be pointing to the symlink. According to Chris (from the ublue discord), this is an upstream Kinoite bug, already reported here.

Ultimately, what I just did is redefine the user’s homedir with usermod, which seems to have fixed it. This won’t work unless you’re logged out, so log from a tty with the root account (if you have one) or make another user that is allowed to sudo:

sudo usermod youruser --home /var/home/youruser

Thank you so much for the help—it works for me on Flatpak Firefox and Chromium.
I’m wondering how to make it work for Zen Browser too. :thinking:

It’s not supported yet, but it seems trivial to add support for it:

// List of Flatpak browsers we support.
const QList<BrowserInfo> supportedBrowsers = {
    {BrowserBase::Firefox, u"org.mozilla.firefox"_s, u"/.mozilla/native-messaging-hosts"_s},
    {BrowserBase::Firefox, u"io.gitlab.librewolf-community"_s, u"/.librewolf/native-messaging-hosts"_s},
    {BrowserBase::Chrome, u"com.google.Chrome"_s, u"/config/google-chrome/NativeMessagingHosts"_s},
    {BrowserBase::Chrome, u"com.google.ChromeDev"_s, u"/config/google-chrome-unstable/NativeMessagingHosts"_s},
    {BrowserBase::Chromium, u"org.chromium.Chromium"_s, u"/config/chromium/NativeMessagingHosts"_s},
    {BrowserBase::Chromium, u"io.github.ungoogled_software.ungoogled_chromium"_s, u"/config/chromium/NativeMessagingHosts"_s},
};

You can probably copy the files manually as a workaround

Thank you so much
I copy the plasma-browser-integration-host file from librewolf folder to /var/home/rain/.var/app/app.zen_browser.zen folder and copy native-messaging-hosts folder to /var/home/rain/.var/app/app.zen_browser.zen/.zen.

Then I edit the org.kde.plasma.browser_integration.json file “path” to where zen browser is "/var/home/rain/.var/app/app.zen_browser.zen/plasma-browser-integration-host",.

But no luck, extension in zen still can’t connect to the host, is there any steps I missed?

Ah, there was this too:

It seems to do it automatically for all the supported browsers, but of course for Zen it does not.

Try running flatpak override --user --talk-name=org.kde.plasma.browser.integration app.zen_browser.zen
