AutoPinTab browser extension

Description

This Firefox extension automatically pins newly opened tabs based on their URL.

To decide the tabs to automatically pin, user must define a set of patterns.
Each pattern could be a plain text URL (like "http://www.google.com") or a JavaScript regular expression pattern (like "^https?\/\/www\.google\.com\/").

Patterns can be configured using the addon options page or right-clicking on the page you want to autopin and selecting one of the AutoPinTab context menu items.
