How can I copy extensions from one computer to another?

I use about a dozen extensions on one computer, and would like to use the same ones with the same settings on another computer. Copying the cryptically-named folders from the ...Profiles/xxxx.default/extensions folder doesn't work - FF doesn't seem to know they are there, even after a restart.

Using FF 3.6.8 on WinXP Sp2

After you copy the extensions folder and all sub-folders, in the profile folder delete extensions.cache, extensions.rdf and extensions.ini, this will force Firefox to rebuild the list of extensions. The problem with this approach is some extensions will create files and folders elsewhere in the profile folder, and many will add preferences to the prefs.js file. I find it easier to have copies of the .xpi files for the extensions and re-install them.

Another way to do this is by using another extension, FEBE.

Hey thanks! I didn't know about FEBE, but it worked just like I needed it to.
