You sure?

What I want to do is sandbox my accounts, specifically my work account. Here's a sceneario

I click a link in slack, I want the link to open in the work container.

How do I do this?

Because using containers, It will default open in the default container, i then have to right click the tab, and say "open in work container" .. which then opens that tab again, in the Work Container.

What I want is to not have to do that extra work. Click link -> Work Container.

You can't, at least, not default... you need to add extra plugins, like Multi-Account containers or whatever the plugin is called. That's a LOT of work for the average user. Compared to profiles where when you click the link, it opens in the last active window, which remembering windows are profiles, will be most likely the right profile. So if im working constantly on my work profile window, i click slack, and then click a link, its right back where i want.

The problem with container tabs, is that its tabs, not windows. So is there any way i can say to firefox "this new window is WORK Containers please"



Looks like there's an extension which adds a new protocol handler, which allows firing the container you like for a given link from the command line.

It's available at https://github.com/honsiorovskyi/open-url-in-container and Mozilla Extension store, so you can directly install it.

I think you can register a new "application" to open links, not set at default, and use Right Click -> Open With -> Firefox (WORK CONTAINER).

Will that work?


This is exactly the reply I was expecting. The "yes it works but here's some extra things you need to do to make it work". No average user is going to do that.

To me containers still don't replace profiles.


Last week I was at a project meeting cum conference, where most people attending were scientists, but not computer people. They have showed what they did with computers and programming languages, and it amazed me with no end.

These people wired tons of plugins on their browsers, VSCode and Obsidian installations, created web sites and tools which broke new ground and their tools were running on distributed systems at very good speeds. Some of these tools requires human years to develop even by “computer people”, yet these people sat with their partners during the pandemic and developed these amazing things while wearing trainers and drinking coffee casually.

These people would make this plugin draw circles up in the air while most of us “not average users” are reading the docs.

So, what is an average user? By your definition I’m an average user, because I use containers, but I didn’t use this extension, but found it in five minutes, because you wanted a solution.

Now I’ll install and use it fully tomorrow morning, before my coffee gets warm. Because it’s worth it.
