I opened Firefox this morning and noticed that the "new container tab" option was missing. I checked my settings to see if I had accidentally disabled containers, and the settings option is missing. After a reinstall of firefox the containers feature is still nowhere to be found. Is anyone else experiencing this bug?

You can check these privacy.userContext prefs on the about:config page.

  • privacy.userContext.enabled = true
  • privacy.userContext.ui.enabled = true

You can open the about:config page via the location/address bar. On the warning page, you can click "Accept the Risk and Continue" to open about:config.

Thanks for the suggestion cor-el. I checked and both of the preferences are true.

Are you using Private Browsing mode as in PB mode extensions do not work ?

Make sure Firefox isn't set to run in permanent Private Browsing mode (Always use Private Browsing mode; Never Remember History).

  • Settings -> Privacy & Security
    Firefox will: "Use custom settings for history"
  • remove checkmark: [ ] "Always use Private Browsing mode"
