opening links in tabs vs. new browsers in Firefox
 

Is it possible to open links in new tabs in Firefox?

right click the link -> open link in new tab

you mean, always or just for certain links?

right click -> open link in new tab

I should have put..."without right clicking"

from other applications?

tools > options > advanced > tabbed browsing > Open links from other applications in > select: a new tab in the most recent window

In firefox I just click the scroll button to open in new tabs :)

get the single window extention

You can hold down ctrl when you click the link.
