Bible Toolbar was an extension for the web browser Mozilla Firefox and was designed to ease searching the Bible at BibleGateway.com. Feel free to checkout the screenshots or read the old blog entries to find out information regarding the project.
Basic features included:
- Search based on keywords or passage references
- Limiting search based on certain versions or sections of the Bible
- Searching two translations side by side
Since the project is no longer ongoing, you should be redirected within 30 seconds to a modern online Bible for your usage.
