Linux support

Does this work on linux as well?

Yes, it does. I just got it working for the Firefox docker container (which is of course Linux based).

You simply put the files in

usr/lib/firefox/userChrome.js
/usr/lib/firefox/defaults/pref/config-prefs.js

Make sure to edit the userChrome.js and in installUnpackedExtensions() remove the example paths and leave only one installExtension line with the path to your own add-on file (e.g. in zip format).

In Docker, I have done this:

To make maintaining easy, I created the folder debug_files in docker/Firefox and placed all required files (userChrome.js, config-prefs.js, addon.zip) inside it.

Now I can map the two *.js files to the required locations and the addon.zip file is simply available through the internal /config path.

To summarize:

Volume mapping:

docker/Firefox  ->  /config   (this is useful regardless of this hack for accessing config and download files)
docker/Firefox/debug_files/userChrome.js  ->  usr/lib/firefox/userChrome.js
docker/Firefox/debug_files/config-prefs.js  ->  /usr/lib/firefox/defaults/pref/config-prefs.js

In userChrome.js modify installUnpackedExtensions() like this:

nstallExtension("/config/debug_files/addon.zip", true);

I'm trying this out now. But I've installed firefox via snap. and so I think the path that I need to add things to is /snap/firefox/usr/lib/firefox

I got this to work with ubuntu 22.04 installed from snap by:

• adding userChrome.js to /etc/firefox/userChrome.js
• and config-prefs.js to /etc/firefox/defaults/pref/config-prefs.js
• apply the changes described in the PR for ff version 117
