I install FireFox for a lot of my clients and tend to install a set of plugins and configurations for the browser. Is there a way to package Firefox with it's settings and plugins and make it easier to distribute?
Yes you can Mozzila; have release a tool called:
It advertised to be able to pre-configure the following:
Deploy options for Firefox (prefs.js, userchrome.css, usercontent.css) Deploy extensions/themes Deploy settings for extensions (prefs.js) Lock down some of the settings (updates to extensions/ app, uninstallation of extensions) Deploy search-plugins (eg. a custom search-plugin for a Knowledgebase in your Org.) Deploy bookmarks Deploy user-interface customisations. (like toolbar settings) A custom namespace icon (Windows only) Customise the help page(s). Name of your Org in the title bar.
You can find more information at the Mozzilla wiki about tools they offer
