# Firefox Multi-Account Containers

76 Hacker News commenters recommended Firefox Multi-Account Containers and 13 criticized it, November 2025 to November 2026. It was recommended in 10 of 13 months; owners who said how long report a median of 7.5 years (3 owners). It meets the Hacker Approved badge rule.

**Verdict:** Recommended for keeping several accounts of one site logged in side by side, and for splitting browsing into isolated containers. Critics say setup is manual and the interface is barebones.

## Why people recommend it

- Multiple accounts logged in at once (7 comments): "Containers are also very useful indeed; I have to log into various different Google and Github accounts and can do this in a single browser window." ([source](https://news.ycombinator.com/item?id=46300378)) "the real killer feature of containers is that it becomes a breeze to use the same service with different accounts & identities" ([source](https://news.ycombinator.com/item?id=49002209)) "I do this a lot and I have dedicated containers for each customer so I can easily switch with out having to log out and in" ([source](https://news.ycombinator.com/item?id=48996841))

([source](https://news.ycombinator.com/item?id=49010257))
- Per-tab proxy or VPN routing (3 comments): "It allows me to access different networks (that might only be reachable via jumphosts or similar) from the same browser." ([source](https://news.ycombinator.com/item?id=48996803)) "With Multi-account containers I get to choose which tabs use the proxy :)" ([source](https://news.ycombinator.com/item?id=49061424)) "Really useful if you route all of your traffic through a VPN by default" ([source](https://news.ycombinator.com/item?id=49046759))

## What people warn about

- Manual setup and site assignment (3 comments): "Firefox multicontainers are pretty cool. But it's an advanced process that most people wouldn't do or do correctly." ([source](https://news.ycombinator.com/item?id=47567744)) "It’s so odd that there is no way to edit the list of sites manually." ([source](https://news.ycombinator.com/item?id=45839600)) "you have to add every Meta domain into that container manually" ([source](https://news.ycombinator.com/item?id=46880800))
- Weaker isolation than separate profiles (4 comments): "My biggest struggle with containers is that I constantly accidentally shift out of them without noticing." ([source](https://news.ycombinator.com/item?id=45837845)) "Firefox's MAC seems like it's not quite as isolated as a separate profile" ([source](https://news.ycombinator.com/item?id=49046849)) "eventually they actually got in my way just as profiles do" ([source](https://news.ycombinator.com/item?id=45939649))
- Barebones, neglected, lacks features (3 comments): "they are barebones and there is so much more that could be added" ([source](https://news.ycombinator.com/item?id=49045397)) "the feature has been sort of "contained" for far too long and not been made flexible/usable enough." ([source](https://news.ycombinator.com/item?id=49043833)) "The containers extension has been languishing for years now." ([source](https://news.ycombinator.com/item?id=49046658))
