multi-account containers as part of "home page" tabs - open without confirmation

I've got my "homepage and new windows" setting set up with several "ext+container links so that my selected websites open in their respective containers : e.g. ext+container:name=Personal&url=https%3A%2F%2Fwww.facebook.com%2F%3Fsk%3Dh_nor

I open facebook in 2 seperate containers so that I can maintain 2 seperate personalities under facebook - e.g. I am a group admin within one, just a group member in another.

I have 2 urls defined in my "homepage and new windows" setting for these :

ext+container:name=Personal&url=https%3A%2F%2Fwww.facebook.com%2F%3Fsk%3Dh_nor ext+container:name=Facebook&url=https%3A%2F%2Fwww.facebook.com%2F%3Fsk%3Dh_nor

This was working fine without any issues. My sites opened up when I started my web browser and everything.

Recently, firefox has started up but my container tabs do not load automatically, I am getting a confirmation (I will post a screen capture as a comment).

Is there a way to turn this off and just open the tabs without a confirmation?

Chosen solution

It looks like this was a security issue. You can create an exception for this protocol by going to about:config and creating network.protocol-handler.external.ext+container (Boolean) with value true.

Added that boolean value in about:config, closed and restarted and everything opened as expected without that additional confirmation.

Thanks! 👍👍👍

So returning to this as its come back again firefox 126.0 on Fedora 40 linux using Firefox Multi-Account Containers 8.1.3

I've got the same bookmarks created as before and I've standardized the "network.protocol-handler.external.ext+container" = true setting as part of my FF setup

When first starting firefox I've got a container tab bookmarked to open Google Voice with my "Google 2" container: "ext+container:name=Google%202&url=https%3A%2F%2Fvoice.google.com%2Fu%2F0%2Fcalls"

Seems the ext+container: isn't recognized properly ...

"The address wasn’t understood

Firefox doesn’t know how to open this address, because one of the following protocols (ext container) isn’t associated with any program or is not allowed in this context.

   You might need to install other software to open this address."

Looks like this was operator error on my part ;)

I had the "Open external links in a container" extension disabled. Once I re-enabled it and restarted, all "open at start" bookmarks work, inc those with containers.
