Incognito & Container Support

Support can be added for Firefox only.
See also: #27

User Interface

Incognito can be supported without any issues. However to support containers as well. there are 2 options for the User Interface:

1. Generic User Interface

Use a generic container list, not knowing or matching the number of containers the user has e.g.

• Incognito
• Container 1
• Container 2
• Container 3
• Container 4

2. Specific User Interface

Get the container list contextualIdentities.query() and create the UI

• contextualIdentities

  To use this API you need to include the "contextualIdentities" and "cookies" permissions in your manifest.json file.

• Adding "contextualIdentities" permission automatically enables containers in Firefox which is undesirable to users who don't want to use containers
• "contextualIdentities" permission is not available as an optional_permissions
• See also: Bug 1386673: Make Contextual Identity extensions be an optional permission

Implementation

• Incognito/Containers can be set to a specific proxy (not patterns or PAC URL)
• Incognito/Container settings will have precedence over other settings (except Tab Proxy)

The checking order would be:

1. Tab Proxy
2. Incognito/Container Proxy
3. Check for "Disable" mode
4. Global Exclude
5. PAC URL
6. Proxy by Patterns or Individual Proxy

To decide

• Should "Disable" disable everything?
• Should Tab Proxy be independent of "Disable" since it has its own independent on/off?
• Should Incognito/Container Proxy be independent of "Disable"?

Sync and Preferences: Import/Export

Container settings may mismatch, if the user has different containers on different browsers.
