Rated 4 out of 5 stars
This is the feature I really wanted. With this addon, I don't have to use an inconvenient feature "Tabs From Other Computers". Just I have to "send" the tab to another computer, then the tab will be opened in the computer automatically.
One point, the "send this page to device" menu is possibly unstable for me. When I initially installed this addon, the menu doesn't appear and it suddenly appeared.
Note: the XPI file of the version 0.2.2 is broken. There is only the file "install.rdf" and no executable code. I had to clone the github repository and build an XPI with the latest SDK by my hand.
