Brothers and Sisters,
I just did a search on the Firefox extensions site for "Bible" and found something great that I want to share with you. It's a Bible TOOLBAR, but it's only available for the older versions of Firefox on the Mozilla site. I did a little bit more reading and found out that the author is still updating the Bible TOOLBAR for new versions of Firefox, and the extension is available on his home page:
http://www.bibletoolbar.net/install.htmlI did install it, and it works great. It's a tiny extension that installs flawlessly in Firefox. It interacts very quickly with Biblegateway.com and allows you to do keyword searches of any two translations of the Bible that you choose. It also allows you to quickly display any portion of either one Bible translation or parallel Bible translations that you choose.
YES - it will open any 2 Bible translations you choose in parallel - side by side, in a format that's easy to see and compare the two translations. I must also add that the toolbar allows quick and easy changes for your selections.The options are very simple. I set mine to open in a new tab. They have an extensive list of various translations that can be used. There are even quick links to commentaries and additional information, depending on which translations of the Bible that you choose.
In short, this little gem of a Firefox extension is tiny, excellent, fast, FREE, and has no strings attached. I have my fonts set larger in Firefox to make things easier for me to read, and it appears that the Bible TOOLBAR automatically uses my larger font settings. So, this extension works just fine for the bifocal and trifocal crowd. 
Love In Christ,
Tom
Hebrews 12:1-2 NASB Therefore, since we have so great a cloud of witnesses surrounding us, let us also lay aside every encumbrance and the sin which so easily entangles us, and let us run with endurance the race that is set before us, fixing our eyes on Jesus, the author and perfecter of faith, who for the joy set before Him endured the cross, despising the shame, and has sat down at the right hand of the throne of God.
