Sorry for breaking this. "isTrusted" is called "isPaired" now.

Yeah, I have the DBUS side sorted, just need to plumb it through the NativeHost interface to the UI, and have ended up down a rabbit hole of extension manifest v3, serviceworkers and general refactoring.

Hey @pdf, what's the status on this? I too see my devices in Firefox, but also the red exclamation mark and can't send, unfortunately.

Sorry for the delay, IRL stuff has had me out of town and time-poor the last couple of weeks.

Thanks for the update! It's great seeing you still working on this. Thank you for all your work!

Subscribing to this issue, waiting for fix.

until (if) this gets fixed, one can use the external application addon, which lets you chose an external binary with arguments and custom icon.

I don't know if external links are ok here... but in worst case it gets deleted:
https://addons.mozilla.org/de/firefox/addon/external-application/
https://chromewebstore.google.com/detail/external-application-laun/bifmfjgpgndemajpeeoiopbeilbaifdo?pli=1

Steps to make this work:

1. Get your device ID: kdeconnect-cli -l
2. Open Extensions Preferences
3. Fill in title
4. Fill in path to kdeconnect-cli
5. for arguments use: -d ID --share [HREF]
6. Enable toolbar Icon option and choose Page, Link, Image and Tab (or a subset of your desire)
7. Choose an Icon
8. Select "Surround Arguments with Quote characters"
9. Hit "Add Application"

Now you should have a new icon in your extensions button menu. Once you click this it opens a page with the link for the native application. Download this, extract it, run ./install.sh

Multiple Devices

You don't get a menu with all your devices. For each device you need to add a separate "Application". Fill in the same details and just change the ID in arguments to match your other devices. Also change the title of the Application.
When you rightclick the extension icon you can then switch your "Applications"

If this seems cumbersome to you, don't call kdeconnect-cli directly, but use your own custom script, which lists all devices using dmenu/rofi/etc and then sends the url to it.

Here is a custom script that uses rofi. the only argument this script needs is [HREF]

#!/bin/bash

_files=( "$@" )

_id=$(kdeconnect-cli -a --id-name-only 2>&1 | rofi -dmenu -p '> ' -mesg "Choose Device")
if [[ -z "${_id}" ]]; then
    exit
else
    _id=$(awk '{ print $1 }' <<< "${_id}")
fi

for x in "${_files[@]}"; do
    kdeconnect-cli -d "${_id}" --share "${x}"
done

Using this approach has another advantage: You can actually see if the device is available. calling kdeconnect-cli directly you will never know if the device was ready to receive data.

Ok, added Instructions to make this work.

@carnager Got it all setup, thanks.

One important thing to note is that the install script provided by the extension creates folders to put the native messaging hosts in even though the corresponding browser isn't installed.
