Hello Khalid,>

For the time being it only works on Firefox Nightly :

Also see this bug report :

https://bugzilla.mozilla.org/show_bug.cgi?id=1407202

And :

I had no idea what Firefox Nightly was, but it seems to have partially solved it. Since the particular web app is the only one that I currently use, I just set its URL as my homepage, and then I click on the button that turns it into an app. So it's more convenient that way. The one downside is that it will open links in the Nightly version and not in the stable version.

Thank you so much for the tips!

This should work as well in Firefox 77 that has browser.ssb.enabled present on about:config (just tested with YouTube via Page actions menu), so no need for unstable Nightly builds.

Note that there is also the --ssb command line switch as mentioned in the bug report.

I'm glad that works for you !

Would you be so kind as to remove the Chosen Solution mark from my post

      Never mind;   James (moderator) already took care of it.
