AutoPinTab extension

Firefox extension that automatically pins new tabs based on their URL.

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


Official (signed) AutoPinTab releases must be installed through Firefox Addons website.

Development releases are unsigned so they require some manual steps to be loaded on Firefox standard edition:

  • download master branch in a ZIP archive, then extract it in a folder of your choice OR clone the whole GIT repository
  • open about:debugging on Firefox
  • click "Load Temporary Add-on" button and select manifest.json from extracted/cloned source files

To avoid these steps you can install Firefox Developer edition (it can be installed side-by-side with standard edition).

NOTE: the unsigned AutoPinTab release will be loaded temporarily, so it must be reloaded each time you restart the browser.


Open a tab you want to be automatically pinned, right-click on its content and select the new AutoPinTab context menu item.

This menu contains items to quickly add current URL to your AutoPinTab patterns.

Now reload the tab (or open a new one) and check if it gets pinned automatically.
