The simplicity of creating new containers for my accounts. I like how you can open a tab for each container and have multiple logins between them. This helps a lot when checking my email from multiple email accounts with the same provider. Review collected by and hosted on G2.com.
I really could not find anything that I disliked about it. It is really that awesome! Nothing hard about it, it is that intuitive. Most other containers are harder to use, but not Firefox Multi-Account containers. Review collected by and hosted on G2.com.
You can mix and match different container tabs in the same window, which is a quite nice seamless experience compared to Chrome et al.'s multi-window profile system.
They also have integrations in a lot of handy places, like you can right-click a link and open it in another container, right click a tab and reopen it in a different container, etc. All the ones I know of get pretty good use here. Review collected by and hosted on G2.com.
Kind of a feature wish, if there were a keyboard way to open a new tab in a container. I thought it was on Ctrl+period, but I think my desktop environment now uses that to open an emoji picker 🤷. So I end up kind of lazy and opening more tabs in no-container mode than I really should. Review collected by and hosted on G2.com.
