## Description

Conductor: Dynamic URL Redirection to Firefox Containers

Conductor is a Firefox extension that allows you to automatically redirect specific URLs to designated Firefox containers.  Take control of your browsing context and enhance your privacy and organization.

Features
<ul><li><strong>User-Defined Rules:</strong> Create custom rules to redirect URLs based on powerful regular expressions.</li><li><strong>Container Support:</strong> Seamlessly integrates with Firefox's built-in container feature.</li><li><strong>Automatic Redirection:</strong> Redirects matching URLs before the page even loads, ensuring you're always in the right context.</li><li><strong>Persistent Settings:</strong> Your redirection rules are saved and synchronized across your Firefox profile (using <code>browser.storage.sync</code>).</li><li><strong>Options Page:</strong> An easy-to-use options page allows you to manage your redirection rules.</li><li><strong>Lightweight and Efficient:</strong> Built with performance in mind.</li><li><strong>Open Source</strong></li></ul>
How to Use
<ol><li><strong>Install the Extension:</strong> Install Conductor from the Firefox Add-ons website.</li><li><strong>Open Options Page:</strong> Go to <code>about:addons</code> (or Manage Your Extensions), find Conductor, and click "Preferences".</li><li><strong>Add Rules:</strong><ul><li>Click the "Add Rule" button.</li><li>Enter a <strong>URL Pattern:</strong> This is a <em>regular expression</em> that will be matched against the URL.  For example:<ul><li><code>example\.com</code>:  Matches any URL containing "<a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/2141eac2eacda036b00afc30fd0a7e6f24e9bddf402cf4393fe5144f468147e8/http%3A//example.com" rel="nofollow">example.com</a>".</li><li><code>^https://www\.example\.com</code>: Matches URLs that <em>start with</em> "<a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/e8fd22f4c7550ae6a1b73e45c11489cead89ac0a50d2a612d5ec48264a9a1b4f/https%3A//www.google.com/url%3Fsa=E&amp;source=gmail&amp;q=https%3A//www.example.com" rel="nofollow">https://www.example.com</a>".</li><li><code>.*\.google\.com</code>: Matches any Google domain or subdomain.</li></ul></li><li>Select a <strong>Container Name:</strong> Choose the container you want to open matching URLs in.  You must have already created the container in Firefox.</li><li>Click <strong>Save</strong></li></ul></li><li><strong>Test:</strong> Visit a URL that matches one of your rules. It should automatically open in the specified container.</li></ol>
Permissions Explained

This extension requires the following permissions:
<ul><li><strong><code>webRequest</code> and <code>webRequestBlocking</code>:</strong> These permissions are necessary to intercept network requests <em>before</em> they are sent, allowing the extension to redirect URLs to the appropriate container. This is the core functionality of the extension.</li><li><strong><code>tabs</code>:</strong>  This permission is used to create new tabs in the specified containers and to manage existing tabs (e.g., closing the original tab).</li><li><strong><code>cookies</code>:</strong>  This permission is required to access the <code>cookieStoreId</code> associated with each tab and container. This ensures that the redirection happens within the correct container context.</li><li><strong><code>contextualIdentities</code>:</strong>  This permission allows the extension to interact with Firefox's container feature, retrieving the list of available containers and creating new tabs within specific containers.</li><li><strong><code>storage</code>:</strong> This permission is used to store your redirection rules persistently and synchronize them across your Firefox profile.</li><li><strong><code>&lt;all_urls&gt;</code> (Host Permission):</strong>  This permission is necessary to allow the extension to intercept <em>all</em> URLs.  Without this, the extension would only be able to intercept URLs that you explicitly listed, which would defeat the purpose of user-defined rules.  The extension uses this permission <em>responsibly</em> to match URLs against your <em>user-defined</em> rules and redirect them to the appropriate containers. It does <em>not</em> collect or transmit any browsing data.</li></ul>
Regular Expressions (Regex)

Conductor uses regular expressions for URL matching, giving you great flexibility. Here are some basic regex tips:
<ul><li><code>.</code> (period): Matches any single character (except a newline).</li><li><code>*</code> (asterisk): Matches the preceding character zero or more times.</li><li><code>+</code> (plus): Matches the preceding character one or more times.</li><li><code>?</code> (question mark): Matches the preceding character zero or one time.</li><li><code>^</code> (caret): Matches the beginning of the string.</li><li><code>$</code> (dollar sign): Matches the end of the string.</li><li><code>\</code> (backslash): Escapes special characters (e.g., <code>\.</code> matches a literal period).</li><li><code>[]</code> (square brackets): Matches any character within the brackets (e.g., <code>[abc]</code> matches "a", "b", or "c").</li><li><code>[^ ]</code> : Matches anything that is NOT in the set</li><li><code>( )</code> : Groups sections.</li></ul>
<strong>Example:</strong>

To match any URL that <em>starts with</em> "<a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/30817b6548cf5af02374327504538370515a5963958c8cdaef43cedeff8e8259/https%3A//www.example.com" rel="nofollow">https://www.example.com</a>" <em>or</em> "<a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/39541a8b4c9bb24f6383cd0a78de9c22eef7b6bcf647bd75853758064e0f1f3a/https%3A//example.com" rel="nofollow">https://example.com</a>", you could use:

<code>^https://(www\.)?example\.com
</code>
