AutoPinTab troch nicorac

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

To decide which 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 one of the pages you want to autopin and selecting the AutoPinTab context menu item.
