HOWTO:tell users how to install .XPI files
From LilyWiki
Installing Lily apps is really easy, but the process may be a little more manual than your user may be used to.
[edit] short and sweet
- download the lily app
- drag the file into firefox
- restart firefox once it's done installing
- look for the new app in the Tools -> menu.
[edit] Longer, but still super easy
- Download the .XPI file to your desktop or where ever you normally would. Just make sure you can locate the file once it's downloaded.
- Make sure Firefox is running. If not, launch it.
- Make sure Firefox has a browser window open. If not, open a new one.
- Find the .XPI file you downloaded on your computer.
- Drag the .XPI file into the open Firefox browser window.
- There will be an unusual prompt asking if it's OK to install the file you dragged into the browser window. Hit yes and it will do it's job.
- Once the file is installed, it will tell you that you need to restart Firefox. Go ahead and hit the "restart" button.
- Now that Firefox is restarted, look for the new application in the Tools-> menu.
- Done! Enjoy!
