Multi-account-containers: Context menu prevail after unistalling.

[chinook77]

Hi, I've uninstalled Containers and the right-click context menu over a link shows "Open link in a new container tab" sub-menu. How can get rid of it without reinstalling/refreshing FF?

[jonathanKingston]

Testing this now.

@chinook77 unfortunately I think you will need to restart Firefox to remove this, it appears to be an issue with Firefox itself.

Do you have any other extensions installed?

• Can you paste the output of about:support page
• Can you provide your OS, version and Firefox version

Thanks

[jonathanKingston]

I can't replicate, STR followed:

• enable privacy.userContext.enabled in about:config
• Install containers test pilot
• Make some container tabs and load pages
• Remove containers
• Uninstall containers in about:plugins

Expected behaviour:

• Container tabs still exist
• Underline on tabs was removed
• Context menu removed
• Browser action removed

I've realized that "Open Link in New Tab" is broken too.

[jonathanKingston]

@kjozwiak are you able to replicate this?

[jonathanKingston]

Maybe this is a dupe of #440

[awlane]

I've also encountered this, although it was preceded by an inability to not open non-Container tabs from the context menu. I'm running the newest build of Nightly on Windows 10 and can dump about:support if you all believe it will help.
EDIT: This persists after a refresh, reinstall, and change of profile.
EDIT 2: Toggling "privacy.userContext.enabled" to False actually fixes it, though it beats me as to how and why.

[kodabb]

@zephyrmoth thanks toggling privacy.userContext.enabled worked for me

[bchauvin]

I'm also encountering this issue this Firefox 55.0.2 (64-bit) in Ubuntu 16.04.
The privacy.userContext.enabled trick worked for me too.

[brettwilcox]

I too wanted to say that I had the "Open Link in New Container Tab" after uninstall. Toggling privacy.userContext.enabled removed the options, but I would expect the uninstall behavior to do this for me.

For anyone curious, it appears that containers were a core feature introduced in Firefox 50 nightly.
https://wiki.mozilla.org/Security/Contextual_Identity_Project/Containers
It is safe to go to about:config and toggle the "privacy.userContext.enabled" to false to remove the containers menu.

Also, the extension basically exposes about:preferences#containers

[tipar]

Same here.

[camy011]

Bump, found this defect was already opened after I wrote up a new one so pasting that information here.

Steps to reproduce

1. Restart firefox with all addons disabled.
2. Install Firefox Multi-Account Containers
3. Remove or disable Firefox Multi-Account Containers
4. Right Click a hyperlink to see "Open Link in New Container Tab" menu option.
