Rated 4 out of 5 stars

Very useful. Find it more reliable and minimal than the "fox/chrome to phone" method.
The only issue would be the resizing of the addon bar, which for a tweaker who is slightly obsessed with maximising screen real-estate makes it pretty much unusable. However, I have managed to create a stylish script that, on my system at least, keeps the icon from changing the default height of the addon bar:

@-moz-document url(chrome://browser/content/browser.xul) {
#linkpush-status-bar {
padding: 1px !important;
height: 20px !important;
margin: 2px -4px 0 -2px !important;

If you use Stylish, go to "write new style">"blank style", paste the above, name it what ever, save.
