How does one acquire add-ons for ffx installed behind firewall?
I have several installations of firefox on platforms behind various firewalls w/o internet access. They are maintained provide easy access to LAN servers containing notes/logs, etc. I have used several addons, specifically the All-in-One Sidebar, for several years. However the current addon page wants to auto-install on active browser instead of providing a download that I can migrate to other browsers. Info in text box below is a MSW platform, but also have several *nix installs that I would like to support.
Question - how does one download and NOT install over active browser, but rather migrate to other offline installations.
