Possible. If you need only the Add-ons to be saved & install offline, you may refer below steps. Or if you're planning to do a full backup, you can also refer Journeyman Geek's Answer.

  1. These files are usually .xpi or .jar files.
  2. Download the file to your local computer.

enter image description here

  1. At the top of the Firefox window, click on the Firefox button, and then click Add-ons. The Add-ons Manager tab will open.
  2. In the Add-ons Manager tab, select the Extensions panel.
  3. To add the downloaded add-on to the list of available add-ons, drag and drop the file into the Add-ons window. The Add-on is added to the list.
  4. The installation process should begin.

That should get your work done.

febe will do the trick - you can both back up things as a single xpi file, or individually.

I haven't used it recently so I can't remember if it backs up settings. Some folk seem to report issues backing up, but that seems to be an issue with permissions more than anytbing else. The nice thing is this is an extention, and I believe cross platform.

For windows, if you want a full backup of your mozilla firefox or thunderbird environment, or more than just xpi files, take a look at mozbackup. Its a third party bit of software that does more complete backups. Its what I use now.
