Configure Firefox

1. Make Firefox the default

   update-alternatives --set gnome-www-browser /usr/bin/firefox update-alternatives --set x-www-browser /usr/bin/firefox

2. Sync

   Set up Firefox sync.

3. Configuration

   Browse to about:config and adjust:

   • browser.enable_automatic_image_resizing = false

   • browser.search.context.loadInBackground = true

   • dom.event.clipboardevents.enabled = ¿maybe?

   • dom.webnotifications.enabled = false

     Notes on eliminating popups: Disable popups

   • geo.enabled = false

   • pref.privacy.disable_button_view.view_passwords = false

   • toolkit.legacyUserProfileCustomizations.stylesheets = true

4. Install Extensions

   Extensions may come over automatically from sync, but this is inconsistent. If necessary, load them manually: Ctrl+Shift+A

   • UBlock Origin

   • Noscript

   • Tree Style Tab (laptop only)

5. Hide UI clutter

   Install custom chrome file. It may be necessary to close Firefox before doing this. mkdir ~/.mozilla/firefox/*default/chrome cp ~/Dropbox/Basic/new_machine/linux/firefox/userChrome.css ~/.mozilla/firefox/*default/chrome
