Be careful with old versions!
These versions are displayed for reference and testing purposes. You should always use the latest version of an add-on.
1. Now packed with Addon SDK 1.6.1, which is leaner and does not have the memory leaks of Addon SDK 1.0, which I had to use to pack the previous version of I2I.
2. To make I2I work with SDK 1.6.1, a lot of code was changed. And now everything works well.
3. Fixed a bug for viewing site's favicon (didn't work for iframes before).
