= Loopback connection =
Thunderbird makes a "loopback" connection to IP address 127.0.0.1 on non-Unix machines. That IP address is the local address of the machine where Thunderbird is running. This connection is not a security problem and should not be disabled. See the Firefox [https://bugzilla.mozilla.org/show_bug.cgi?id=100154 bug 100154] for more information.
= Auto-update checking =
{note}'''Warning''': You should install Thunderbird updates as they become available in order to secure your system against vulnerabilities. Therefore, we do not recommend that you disable update checks.{/note}
Thunderbird periodically checks to see if updates are available for itself or for installed add-ons (extensions, themes, etc). To disable these checks:
# [[T:optionspreferences tb]].
# Select the {menu Advanced} panel.
# Select the {menu Update} tab.
# Uncheck '''Thunderbird''' and '''Installed Add-ons'''.
= Home page loading =
By default, Thunderbird automatically loads a page with the latest Thunderbird information when the application is started. This page is downloaded from the internet. To prevent Thunderbird from loading this page:
# [[T:optionspreferences tb]].
# Select the {menu General} panel.
# Uncheck '''When Thunderbird launches, show the Start Page in the message area'''.
= Add-on list prefetching =
Each time the Add-ons window is opened, Thunderbird pre-fetches a list of add-ons to improve responsiveness of the {menu Get Add-ons} pane. This connection is only made when the add-ons manager is opened.
= Extension blocklist updating =
{note}'''Warning''': Disabling blocklist updating is not recommended and may result in you using extensions known to be untrustworthy.{/note}
Mozilla maintains a list of extensions that are not approved for use with Thunderbird. Thunderbird downloads this list from the internet. To disable:
# [[T:optionspreferences tb]].
# Select the {menu Advanced} panel.
# Select the {menu General} tab.
# Click {button Config Editor}.
# Enter {pref extensions.blocklist.enabled} in the {button Filter} field.
# Observe the '''Value''' column of the {pref extensions.blocklist.enabled} row.
#* If it is set to {pref false}, then do nothing.
#* If it is set to {pref true}, double-click on it to set it to {pref false}.
= Extensions =
Installed and activated extensions may connect to the internet. For example, a translation extension might connect to the internet to look up words in a dictionary. See the [[Add-ons FAQ]] for information about disabling add-ons.
