Rules

While we are not an official Mozilla community, we have adopted the Mozilla Community Participation Guidelines as far as it can be applied to a bin.

Rules

  1. Always be civil and respectful
    Don't be toxic, hostile, or a troll, especially towards Mozilla employees. This includes gratuitous use of profanity.

  2. Don't be a bigot
    No form of bigotry will be tolerated.

  3. Don't post security compromising suggestions
    If you do, include an obvious and clear warning.

  4. Don't post conspiracy theories
    Especially ones about nefarious intentions or funding. If you're concerned: Ask. Please don’t fuel conspiracy thinking here. Don’t try to spread FUD, especially against reliable privacy-enhancing software. Extraordinary claims require extraordinary evidence. Show credible sources.

  5. Don't accuse others of shilling
    Send honest concerns to the moderators and/or admins, and we will investigate.

  6. Do not remove your help posts after they receive replies
    Half the point of asking questions in a public sub is so that everyone can benefit from the answers—which is impossible if you go deleting everything behind yourself once you've gotten yours.

Or what do you use them for? Isn't it now quite easy for websites to track outside of just cookies?

I have anything google, anything shopping, anything banking in separate containers.

I also have separate containers for multiple accounts on Github/Gitlab

addendum: what's also neat is that I can define a page to always be opened in a specific container. so when I just open new tab and open YouTube, its already in the Google container

Combined with container bookmarks extension, it becomes really handy.

Amazon, i can login as my personal or my company account based on the bookmark I click

Social media, different profiles straight in with their bookmark

I manage a few things for my mother, utilities and such, keeping her logins already logged in in a bookmark folder is handy.

Essentially, any time you need to segregate logins / accounts.

Super reasonable. I should get with the times and start using it too...

As i say, it really comes into its own with the container bookmarks addon

https://addons.mozilla.org/en-US/firefox/addon/container-bookmarks/

It can be a bit of pain to get setup with containers for bookmarking, but if you get stuck feel free to shout

might have to give this container bookmarks a look. I'm looking to move away from Zen browser. the 1st best thing for me on zen is their workspaces, and that can set containers to open specific containers only. 2nd best thing is each workspace can have its own pinned tabs.

but I just lost a lot of tabs because of a zen bug.

so I figured this container bookmarks can replace that workspace pinned tabs.

Yeah, i have a combination of a selection of folders in bookmark bar for various functions and a home page / speed dial again with bookmarks which are container enabled, makes my workflow much easier.

Separate accounts for the same site is just about the only use case nowadays since Firefox started implementing isolation per-site.

[–] TVA@thebrainbin.org 6 points 2 days ago (1 children)

For anyone in IT who works in multiple tenants or with multiple clients that use the same site(s), it's an absolute gamechanger

[–] core_of_arden 8 points 2 days ago

As already mentioned. It's really handy for keeping accounts separate. It's also very handy when it comes to keep tracking separated. Keeping your google sites in one container, your FB in another, your bank in another an so forth...

[–] MicrowavedTea@infosec.pub 8 points 2 days ago

Maybe a niche use case, it's extremely handy for testing an application with multiple users. Everyone else at work seems to be keeping 3 browsers open at all times just for the separate logins.

I use them quite heavily in combination with Cookie Autodelete. I then create a separate profile for each surveillance capitalist service I work with. So for example, here's my list of containers:

A screenshot of my container list

Every time I visit one of these sites, Firefox opens them in the respective container, and the cookies they create are isolated to that container. When I'm in the LinkedIn container, Cookie AutoDelete nukes every cookie that isn't from LinkedIn (including Google, GitHub, etc.). When I'm not in any container, all cookies are deleted everywhere.

Basically it's a nice way to leverage Cookie Autodelete without having to whitelist Big Tech for all my browsing.
