===How can I install calendar in my current Version of XY? It doesn't work. ===
Download the most recent calendar.xpi. Open it with your favorite zip-program. You might need to rename the .xpi to .zip. But don't forget to rename it afterwards. Extrakt Extract the install.rdf and edit the var <em:maxVersion> of the Application you want to use to the Version you are using. I.e. 1.0 -> 1.0+ or 1.0->1.1 or whatever. Repack the install.rdf. Now you should be able to install it.
You can also try the [https://addons.mozilla.org/extensions/moreinfo.php?id=958&application=firefox Nightly Tester Tools], which have an option to override the compatibility test.
