Thunderdird seems nopt able to access non-email web addresses: mozilla start-up page, addons, and google calendar.
System -Linux Mint 12, Thunderbird 45.5.1
Thunderbird cannot open the Mozilla start-up page; the"get addons" page shows "server not found services.addons.mozilla.org"; and, my google calendar cannot be accessed. All email accounts (imap) function ok, and browsers work fine on the computer. The add-ons website services.addons.mozilla.org can be seen in a normal web browser. My urgent problem is the google calendar, now compounded by Thunderbird being updated but unable to update Lightening due to addons not available!
