You can install firefox (or thunderbird) addons for all users of the same system. (See how-to-add-a-thunderbird-addon-globally, same applies for firefox)

How can these be automatically updated?

  • When you open Firefox and go too about:addons, does it offer to updates the addons? It may be able to update with by installing local user copy of the addon.

  • @Wilf: no, it does not do so by default

They can't, that's the downside of this method.

(Except if they're isntalled through your distribution's package manager and there's an update through those...)

  • How about a manual update process (wget etc. via cron)? Is that possible?

  • You could do that, yes. The point is that you can't do it from within firefox. Aug 8, 2015 at 5:41
  • Yes, but "from within firefox", installing an addon globally has never worked, either. YMMV

    It probably would be possible to make a script to do the update - alternatively you could do a packaged version (rpm example, deb example), update the packaged version, and then include it in a repo/ppa/copr/whatever to update it.
