I would like Firefox (the new super fast Quantum with low memory usage) to open some URLs in a special/popup window, i.e. almost without anything (toolbar, menu bar, tab bar, address bar, etc.) other than the web content.

At the moment I can only do something like this by clicking a link in an HTML file with the following code:

<a href="https://web.whatsapp.com/"
   onclick="window.open('https://web.whatsapp.com/','popup', 'width=650,height=900');">

I wish I could do this by simply entering a command from terminal - or a standalone shell script would also do (ideally without the address bar, and positioned to the right and not left ;-)

Any suggestions or ideas please?

  • Have you checked the man page for firefox? I would be pretty surprised if there isn't an option to do this (I know for Chrome it's --app, but I bet Firefox is different). Nov 16, 2017 at 19:50

    In the absence of such an option I've created a Q&A concerning this matter here: unix.stackexchange.com/questions/410043/…
