Several months ago, I started using RefTagger from Logos on this site. That free code snippet automatically adds hyperlinks to any Scripture reference I type in a post here. That link will take you to the passage (online) and display a pop-up box with the verse(s) in it when you hover your mouse over the link.
That’s fine for my blog, but what about the dozens of other blogs I read (many of which don’t use RefTagger)? Refalizer adds a very similar feature to Firefox so that you can have a hyperlink for every reference displayed in your browser. (Well, almost every. I typically use a period between the chapter & verse numbers and Refalizer quits at the period and only links to the book/chapter. Perhaps that’s an update coming soon?) Still, it’s quite an improvement over opening another tab to look it up “the long way.” And as a Firefox extension, it’s a cinch to install. It access a half-dozen or so different online Bible sites and offers quite a number of translations. You can pick your personal favorite in the preferences (open “Addons” and click “Preferences” on the Refalizer extension box).
You can download the Refalizer extension here.
