How to backup and restore downloaded gnome-shell extensions?

I guess I figured it out. You have to replace (after backuping, for safety) the following three folders with the original ones previously saved from the system you want to clone:

~/.local/share/gnome-shell/extensions

~/.local/share/gnome-shell/quicklaunch

~/.config/dconf

Then logout and login.

Let me know if it works, or if you find better ways!

(tested on Ubuntu Gnome Shell Remix 12.04)

The downloaded gnome-shell extensions are stored in the .local/share/gnome-shell/extensions folder in your home directory folder. Copy the extensions folder and store them in somewhere else.

When you need to restore those extensions, copy and paste the stored extensions folder in your .local/share/gnome-shell folder. Logout and Login.

The easiest way so far is to use the chrome connector.

All you have to do is to right click the extensions, go to options and make sure "Synchronize GNOME Shell extensions list" is enabled. After you reinstall ubuntu you need to install this chrome extensions again and disable/re-enable this sync options. You will be prompted which extension list to use, remote or local and you can chose the remote list.

Only caveat i have found so far is that the extensions settings are not backed up too.
