I installed a virtual machine on VirtualBox. My host machine is Ubuntu 12.04 LTS. My problem is that I found all the addons of Firefox of the host Ubuntu in the Firefox browser of the guest machine.

In the guest machine, when I check the folder where the addons are saved, I do not find anything, but from its behavior, I guessed that it has all the capabilities Firefox-hostmachine has (for example I can watch Youtube on the VM without installing an approriate addon).

How can I avoid that the addons of host machine to be used by the browser of the virtual machine ?

  • Which flash-player did you install on your host-machine? – jobin Jun 12 '14 at 13:37
  • I installed Adobe Flash on the host machine. – user284234 Jun 12 '14 at 14:03

Firefox (and Chrom(e/ium) can sync your password, add-ons, bookmarks and more from any device to any other device. For firefox it is explained in this link. From chrome here.

You have this enabled it seems ;)

  • The link explains that only add-ons installed from Firefox's add-on repository are synced. How come flash-player was installed (I believe it is Adobe flash)? – jobin Jun 12 '14 at 13:35
  • I did what the picture shows on the link, and I got the result I wanted. But I do not know how the addons of the host worked on the firefox of the VM without needing to be installed. – user284234 Jun 12 '14 at 13:41
