It’s quite simple to add to your Firefox browser. Just enter the FXChrome add-on page and install it. After finishing the installation, restart Firefox. Now Firefox should look exactly like Google Chrome. Note: One problem I noticed with this add-on is that, it misses close button on opened tabs. To close a tab, you need to right click and choose close option. FXChrome is available for both Windows ands Linux version of Firefox browser at here.
