For a long time, there was no new addons for Mozilla Firefox. Now, Link Target Display puts an end for the longing for the Firefox lovers. It is an add-on, which displays link target in a tooltip at the bottom of the browser window if you have hidden the status bar. Usually, the status bar will be hidden automatically in fullscreen mode and you can hide it permanently in the View menu if you don’t want it to have.
If you will start using this addon, you can come out of your pressure of looking at the links in a tooltip and searching the hidden status bar.
