DOI Puller por Chuiden

About
A simple open-source Firefox extension that pulls DOI numbers and metadata from academic journal websites (JSTOR). Pulls from the page source for conveniently copying undisplayed DOI numbers from certain articles.

This extension has been tested on Firefox and JSTOR only as of May 2026. This extension only extracts the GA Data content from JSTOR pages with DOI number and additional metadata. May work on other websites that store DOI in gaData.content objects.

Popup Options
You can customize the display of the extension popup, as well as the content display on refreshes, in the popup window. Settings are persistent.
* Toggle Extractor on Current Page: Opens and closes the popup window
* Enable Persistent Dragging: When disabled, stays fixed on the top right of the page. When enabled, enables dragging and moving with the window scroll
* Theme: Light, Dark, and Soft Colors

Content Display
The display window appears and closes when the Toggle Extractor on Current Page is pressed. Default shortcut is Ctrl+Shift+F. The data displayed is extracted under the gaData.content object from the source page.

Future Updates
* Additional website and object support / sci-hub compatibility
* Export function / auto-copy DOI settings
* Persistent window across pages
* More customization
