Container Redirect

!!! NOTE !!! It's a fork of a great extension containerise (with some small fixes and additions). All the fame and glory goes to its author kintesh. The original extension is not maintained anymore hence this fork. New features and enhancements are not planned currently, bug fixes and some bits and bobs at best.

Firefox extension to automatically open websites in a container

Select your container and add a domain to always open all visits in the chosen container.	Add many domains as you wish.	Special No Container option to break out of a container.	Simple CSV based mapping of a domain to a container by name for easy backup and bulk editing.

Installation

Install the latest release for Firefox from AMO

Usage

Glob pattern

Glob patterns cover most common cases (see the examples below). For more complicated scenarios, use regex patterns.

1. If a pattern contains only a domain, we try matching only the URL's domain (the whole domain). For example:

• if the pattern is duckduckgo.com, then URLs https://duckduckgo.com, https://duckduckgo.com/?q=search+me+baby will match the pattern but URLs https://google.com, https://google.com/?q=duckduckgo.com will not match the pattern.

• if the pattern is *.duckduckgo.com, then URLs https://subdomain.duckduckgo.com, https://subdomain.duckduckgo.com/?q=search+me+baby will match the pattern but URLs https://duckduckgo.com, https://google.com/?q=subdomain.duckduckgo.com, https://evil.duckduckgo.com.evil.com will not match the pattern.

2. If a pattern contains only not only a domain but a path, we try matching the whole URL. For example:

• if the pattern is duckduckgo.com/\?q=search+me+baby, then only URL https://duckduckgo.com/?q=search+me+baby will match the pattern. Notice that ? is escaped with \. Since * and ? are glob meta-characters, you need to escape them if you want them to be interpreted literally.

• if the pattern is *.duckduckgo.com/\?q=search+me+baby, then URL https://subdomain.duckduckgo.com/?q=search+me+baby will match the pattern.

The glob meta-characters *, ? are converted into the regex characters .*, .? under the hood so there can be more than one such a character in a pattern.

Regex pattern

Regular expressions should be used when using of glob patterns won't work. A few examples:

1. Search for a pattern anywhere in the URL. For example, pattern @duckduckgo and URL https://duckduckgo.com/?q=search+me+baby.

2. Search for a pattern in the URL's path but not in the domain. For example, pattern @.*?/.*duckduckgo\\.com.* and URL https://google.com/?q=duckduckgo.com.

Matching with existing container name (settings option 'Match current container name'):

The expression inside <...> must be a valid regular expression (<> is an exception to map to No container).

Examples:

• <>amazon.co.uk, Shopping will open all amazon.co.uk (not subdomains) links in the Shopping container but only if the current tab is not assigned to any container (<> at the begining means No Container)

• <shopping>@(?!.+\.amazon\.co\.uk).*, No Container will open all links from inside the Shopping container that are not .amazon.co.uk subdomains in the No Container

• <^(?!Profile \d$)>@.+\.facebook.com, Profile 1 will open all links to facebook.com in the Profile 1 container unless the current tab is already assigned to Profile 1, Profile 2, Profile 3, etc.

CSV Editor

You can use a CSV editor to set up the container rules (pencil icon). The rules have the format of host/URL pattern, container name, container color (optional), container icon (optional). For example,

www.reddit.com , reddit , orange , fruit
google.com , Google , blue , fingerprint

If the container defined in the rule already exists, the values of the color and icon will be ignored (the values of the already existing container will be fetched and used when the changes are saved).

If the container defined in the rule does not exist, it will be created. If the optional values (color and icon) are not set, random values will be chosen.

Integration with Mozilla Addons

Temporary Containers, Temporary Containers Plus

To prevent some issues, Temporary Containers and Temporary Containers Plus are allowed to request containers' patterns.

Development
