As many of you are aware, Firefox had discontinued support for web app installations; it may resume at some later date, but this is speculation at this point.
However, don’t let that discourage you.
There are workarounds to this. Although it’s a bit of a hack and doesn’t provide a seamless web app experience (there will be a title bar and no app management page, for example), I have written a guide to emulate the behavior of a true Firefox web application. This is performed by creating a dedicated Firefox profile for a website and placing an icon for the profile in the application gallery.
I’m open to suggestions to improve the guide if you find a better approach or if you discover a way to automate this. Feel free to leave comments here or on the snippet itself.
I actually made a similar script a few days ago but it is lacking in a number of features such as downloading and parsing any potential manifest data and providing a default desktop icon (possibly using the favicon as a source). It is probably possible to do these things using existing tools in a shell script but I feel it will likely become a messy script, which it already is.
Feel free to extend and fix issues with this script:
Usage:
ffpwa.sh # Requires `yad` package to be installed; a GUI will appear to enter the name, description, and the URL.
ffpwa.sh -D <profilename> # This will remove the `.desktop` and profile directory BUT you will also need to manually delete the profile from Firefox with the profile manager using the command `firefox -P`. There's unfortunately no way to automatically do this.
~/.local/bin/ffpwa.sh (You can rename this to whatever you want such as create_pwa.sh and even remove the file extension to make it easier to execute):
#!/usr/bin/env bash
#
# See: https://wiki.mozilla.org/Firefox/CommandLineOptions
PROFILES_LOCATION="${HOME}/.local/share/ffpwa/profiles/"
DESKTOP_ENTRIES_LOCATION="${HOME}/.local/share/applications/"
if [ -d "${PROFILES_LOCATION}" ]; then
mkdir -p "${PROFILES_LOCATION}"
fi
while getopts "D:" opt; do
case ${opt} in

done
if [ -n "${DELETE_PROFILE}" ]; then
profile="${PROFILES_LOCATION}/${DELETE_PROFILE}"
desktop="${DESKTOP_ENTRIES_LOCATION}/ffpwa_${DELETE_PROFILE}.desktop"
rm -rf "${profile}" "${desktop}"
echo -e "Deleted profile files '${DELETE_PROFILE}' at '${profile}' and '${desktop}'\nYou MUST manually delete the profile from Firefox using \`firefox -P\` or by typing 'about:profiles' in a browser session."
exit 0

firefox -CreateProfile "${NAME} ${PROFILES_LOCATION}/${NAME}"
echo -e "Firefox profile created at '${PROFILES_LOCATION}/${NAME}'"
# Create a desktop entry (Linux).
DESKTOP_ENTRY_LOCATION="${DESKTOP_ENTRIES_LOCATION}/ffpwa_${NAME}.desktop"

Regarding the Exec=firefox -P "${NAME}" "${URL}" %u # --kiosk line, you may want to enable the --kiosk mode to run the “app” in full screen mode when it launches.
I think if I want to make the app/script more flexible, I might need to create a CLI app with a proper programming language instead of a shell script.
To make the configuration automatic, you can create a user.js file in the profile directory. The arkenfox user.js project has a good number of configurations for reference but the entire arkenfox configuration file is likely not suitable for this purpose if taken as-is.
I’m using that on my Windows machine for installing ProtonMail webmail as separate app. I haven’t tried it on PureOS, but at least the project has deb packages available.
That extension/native app works, even on the Librem 5. I removed the guide from the Librem 5 wiki, though it can work if you manually download Firefox. Librewolf stopped producing native binaries, opting for AppImages and Flatpak.
I was tinkering with this yesterday and was able to get if to work by duplicating the firefox-esr directory that comes with PureOS on the Librem5 (had to fix permissions and symlink firefox-esr to firefox to get it to work. Hopefully its a safe setup lol).
The good news is firefox web apps work, icons look great, slight performance increase, more space on screen because of less UI. Bad news is app management requires connecting to a monitor because of the firefox extension panel issues. Annoying but not the worst issue to deal with. Once apps are installed they seem to work well so far
Glad you got it working and that it’s provided a performance bump!
Can you elaborate? Are you saying that the extension panel is hidden? If so, I had worked around this for brief adjustments by temporarily setting the screen resolution to 100% scaling.
I don’t remember having to do anything like that. Which folder did you duplicate? A new Firefox profile (created in firefox-esr -ProfileManager) is stored within $HOME/.mozilla/firefox/<profile_name>.
Update: a known limitation is that the firefox process appears to linger around after closing the application, and this can cause system unresponsiveness/crashes over time. I would like to test this by appending a kill clause to the .desktop file, perhaps similar to what @user0 did for the chatty application:
Until then, I’m working around it by periodically checking for and killing stale firefox processes with ps -ef | grep firefox.
Apologies, I should clarify that I was talking about the Firefox extension posted by maneth.

Haha, admittedly this is obvious but I didn’t think to try that - I will!

I’m away from my L5 so I’m going by memory here but I believe the extension tries to download Firefox directly - but as there doesn’t seem to be an ARM64 version on the site it tells you to do the “advanced setup” where you have to download Firefox (or similar browser) and place it in the specified directory it requires. So what I did was literally duplicate the entire Firefox-esr application folder and move the copy to the “runtime” folder it tells you to use. Then I had to make a symlink from firefox-esr to “firefox” (I guess that’s what the extension is looking for) and fix some ownership permission issues to make it belong to the local user. After that it worked

Ah you know what, my L5 did actually hang and become unresponsive after trying to unlock it last night but I thought it was unrelated. Looks like it may affect that plugin too. Nothing is ever easy, lol…
BTW: Did you manage to figure out any solutions / insights to this?
This issue also appears to be happening to me with the firefox PWA plugin. About every 24 hours I get a full system crash which requires a restart so definitely seems to be an issue with Firefox itself as far as I can tell.
Unfortunately not, but I admittedly haven’t spent much time looking into it. I’ll dig into it more this week. As a temporary workaround, I’ve been using the sledgehammer approach every once in a while after closing my firefox sessions… killall firefox-esr 2> dev/null
@JCS, Yeah, I’m doing something similar at the moment too. It seems to me that the same web app creates multiple processes over time, even if the app isn’t closed.
It’s a shame because performance-wise, firefox definitely runs web apps better than epiphany - minus the memory leaks of course.
If you do manage to make any progress on that front, please share!
