A few others: - Temporary Containers[0] - Google Container[1] - Google Container w/ Integrations (YouTube, AdTech, Apps, etc)[2] - Reddit Container[3] There are a few others[4] as well, but I've found the Temporary Containers solves the 80%. -- [0] - https://addons.mozilla.org/en-US/firefox/addon/temporary-containers/ https://addons.mozilla.org/en-US/firefox/addon/temporary-con...

You can make all of these yourself as long as you've got the Temporary Containers add-on installed. I don't see the benefit of installing four addons for this purpose, as the security risk of third-party addon vendors surely outweighs the convenience of a pre-configured container.

  Has temporary containers gotten the feature to drop the container when leaving the target sites? That's the main difference for me. If I'm in FB Messenger and click an external link I don't want that link to be opened in the FB container.

    I use per-domain isolation, so I don't run into this issue. However, I need 2 manual persistent containers for sites that are broken with per-domain isolation (Gmail and Outlook 365). Both visit many different domains after login. Within those containers, I need to be careful not to click on external links, but to open them in a new temporary container.

    I think it's actually just a containers feature now: https://news.ycombinator.com/item?id=24850878 https://news.ycombinator.com/item?id=24850878

Worth pointing out that while they're probably safe (and do in fact use the same container APIs to separate out the domains), these are all from third-party developers. Where as the Facebook container is from Mozilla directly.

  Multi-account containers IS made by Mozilla, actually

Is it possible to have each domain open in a persistent container? It looks like Temporary Containers uses a new one each time a site is visited. Containerise, on the other hand, seems to need to know about each domain in advance.

  I use persistent containers based on domain. Works brilliantly.

      I only use the official "Firefox Multi-Account Containers" (on this browser). It gives me a menu with choices like "Reopen This Site in..." and "Always Open This Site in..." as well as options to open a new tab in any of the permanent containers or even open new ones. Tip: if anyone gets confused by a page popping up, saying something like "You asked me to always open this site in, do you still want to " a typical explanation for me was I had set at site to open in a specific container but as part of login procedure it would access another domain for sso, trigger "Always Open This Site in..." for that domain and get confused. Now that you know this you should probably be able to either avoid it completely by being specific about subdomains or something. It is not a big thing, just a heads up so nobody gets confused.

Do not use Temporary Containers. This extension to Multi-Account Containers looks great at first -- its Automatic mode spins up a new container each time you open a new tab, then switches that tab to an existing container, should one be associated with the TLD you visit. The problem is that Temporary Containers does not delete these temporary containers. They accumulate in the MAC containers list. There is no way to mass delete them, nor set them to auto-delete when the tab is closed. These WILL sync to your Firefox account and reappear on every machine. Over 3000 temp container made MAC unusably laggy. This was so destructive of my MAC experience that I uninstalled both extensions. Unfortunately, to my knowledge, there is no way to reset the data MAC syncs to Firefox Account.

  Temporary Containers has an option "Delete no longer needed Temporary Containers" which defaults to 15 minutes, but can also be set to immediate. Are you setting this option to something else? Temporary Containers works really well for me. I have per domain isolation, which only breaks very very few sites (Gmail and Outlook 365). For those I have regular persistent containers. Alternatively, I can always open a new private window where I don't have this plugin active. uBlock Origin + Temporary Containers + ClearURLs are a great setup for privacy and security. Actually, I don't need much else aside from a VPN and a few settings in my user.js. The only thing I miss is Vimperator. Modern alternatives are full of glitches because of inherent limitations in the WebExtensions API.

    It's a long-standing bug that also affects me. It's quite annoying since it's easy to irreversibly hose up your sync account by going over the remote storage quota. Maybe you don't have a Firefox account and/or sync setup? There are related issues opened for Temporary Containers, MAC and Firefox and at least from the public discussions not much is happening about it.

      I use Temporary containers heavily and the MAC sync is also enabled but I never see anything like this. Sometimes 1-2 container it remains but I can delete it manually. Maybe I'm lucky with this.

The issue with this was using multiple Google identities. The Google Container Extension would want to open any other Google sites in the same container. I wanted to keep the soccer club administrator, school website, etc. Google identities separate and distinct. Perhaps things have changed and this isn't an issue anymore. What I did was create an identity (soccer, PTA) for each gmail account and set defaults for google.com, YouTube.com, etc. Having MTTSCPresident@gmail.com is really nice for being able to give someone else the password and let them take over the account when your term is done.
