Rated 5 out of 5 stars

To make this work in 3.6, you have to do 2 things.
-Fix the maxversion in install.rdf
-Add the chrome.manifest file. You can write it yourself, or let it generate by an old version of FF. Since most of you probably used AutoCopy before, you'll find the chrome.manifest file in a folder that looks like this.
C:\Users\yourname\AppData\Roaming\Mozilla\Firefox\Profiles\asfsfsdf.default\extensions\{0FED7D55-65D4-47b6-A6DE-9A4ADB55355F}\
If you are lazy you can just use my edited xpi file:
