What ho one and all,

As a Luddite, I am reluctant to constantly upgrade. My Firefox 38 ESR is working fine, and when I have tried to upgrade, many of my extensions are disabled.

One of my most useful is currently, Evernote Clearly. It does what it says on the box but is no longer supported and is unavailable. As I do not have the original *.xpi file, is it possible to copy the file from D&S/Rex/AppData/ Mozilla/Firefox/Profile/Extensions to the Extensions folder of a new version and it will (may be) work?

Toodle pip and thanks

Rex
