Brave browser seems to have a working version of Firefox-style Containers, and some users are already using it on the main browser, not just the experimental Nightly build.
A Redditor spotted the feature and posted about it on the r/brave_browser subreddit. The user enabled a flag at brave://flags labeled “Enable Containers,” restarted the browser, and from there was able to open tabs in isolated containers.
The practical example they gave: being logged into two separate Google accounts at the same time, in the same window, without needing a second profile or a separate browser window. That alone is notable for anyone who juggles personal and work accounts daily.
For anyone unfamiliar with Containers, the short version is that each container keeps its login sessions, cookies, and browsing data separate from the others. Open Gmail in one container, open it again in another, and neither knows the other exists. Firefox has had this for years, and it became one of the more quietly beloved features among power users.
The feature is still a work in progress. Opening a link in a container requires you to have the site already open in a regular tab first, then right-click it. You also cannot open a bookmark directly into a container yet. Not exactly smooth, but functional enough that people in the thread are actively using it day-to-day.
Brave’s own community forum has had discussions around the feature going back to early 2025, and GitHub activity shows the team has been tracking container-related issues for a while. This feels like a feature that has been slowly baking.
Interestingly, the OP noticed that the brave://flags entry for Containers specifically lists Android as one of the supported platforms. That could mean nothing right now, or it could mean mobile support is on the roadmap. Hard to say for certain.
Several users said Containers were the main reason they had kept Firefox around. Whether or not this rolls out more broadly or officially soon, it looks like Brave is getting close.
