HTTPS-Everywhere 3.4.2 Firefox ESR 17.0.9 Slackware64 14.0 To reproduce: - right click on the add-on toolbar to open the popup menu - click Customize - a window will open, containing icons related to misc Firefox actions or to Firefox add-ons - there's no icon for HTTPS-Everywhere Note: when HTTPS-Everywhere gets installed - it adds an icon to the Navigation Toolbar only. This is inconvenient for me because my Navigation Toolbar is always hidden (I am using the Pentadactyl addon). Being able to have a HTTPS-Everywhere icon in the Add-ons Toolbar would be very handy.
