Hello,
when I assign a site (for instance a google table) to a container and I wanna open another site (for instance another table) it wants it to open in the same like the first one. But I don’t want that.
I dont want to assign a domain name to the container but a specific website.
Is there a workaround?
Another example:
I assigned “https://www.google.com/finance/” to a container.
But now everytime I google anything it also wants to open that google search in that container.
Currently, Multi-Account Containers doesn’t support assigning based on URL pattern. So you’re limited to full domain name or subdomains.
There’s a third-party addon called Containerise (https://addons.mozilla.org/en-US/firefox/addon/containerise/) that supports more complex URL matching rules that you might like to give a try.
The UI is really lacking here. I am looking for some way to open pages in containers based on url pattern or at least exact url. E.g. I want to efficiently work with a example.com/loginInAsAlice and example.com/loginInAsBob. For that I want to create bookmarks to both urls, and each of them should be opened in different containers.
Unfortunately, that add-on is “not actively monitored for security by Mozilla”.
There is no way I’m giving full access to all my browsing to such a completely insecure add-on.
Thanks for the well intended tip anyway. 
Hi there,
Is there any way to add parameters to a URL to open in a container, not just an extension?
I find URL-matching to be insufficient. I have 3 different gmail accounts, for example:
I’d like to be able to link them in my homepage so that they open directly in the container. Something like work:htpps//mail.google.com
Is that possible?
