How-to: Click & drag to open links in Firefox
Here’s an undocumented – as far as I know – feature for OSX users. Rather then CMD + ‘clicking’ to open links in a new tab, try dragging links to your tab bar. Additionally, incomplete text links such as uneasysilence.com can also be opened using the highlight then click + drag to tab or address bar to open. The last time I checked, the following functionality was not available to Windows users unless the SuperDragAndGo extension was installed (currently fubar for the updated Firefox version).
Also worth noting is the ability to drag n’ drop links from emails from Apple’s Mail.app. The same functionality applies – highlight inactive URLs and drag into Firefox’s tab or address bar to open. Depending on your tab preferences, dragging links into a background browser window will generally open the website in the foreground.
Note: This will work with the Flock browser as well.

Works on Windows, too.
This also works with Camino. :)
Good to hear that it works on Windows. I tried to do this under Parallels booting XP and for some odd reason I wasn’t able to get it to work. We’ll all take your word for it Roland.
Stridey: Good to hear it works in Camino as well.
for incomplete urls i use this greasemonkey userscript http://ergosum.frac.dk/user/linkiTing.user.js to turn them into links.
Good to know these things… thanks!
I just tried myself Roland is right it is working on Windows too :) Thanks for the tip!
mine works on windows too
Works with Safari too. Works in Opera 9.0 for Mac, but don’t drag through the link or it will just highlight it. I have to drag it straight up and then to the tab bar. I just dragged sideways through Ronald’s link and it still worked in Safari. Have a Blessed Day, Mike
you can use the same feature for images, drag them to the tab bar to open in their own tab
