Include the localizable strings for the about:tbupdate page
in Torbutton.

Kathleen Brade authored Oct 14, 2015 and Georg Koppen committed Oct 30, 2015

Removed torbutton_weblistener and torbutton_check_progress().

Removed torbutton_wrap_search_service() function,
  torbutton.prefs.fix_google_srch entities, and
  extensions.torbutton.fix_google_srch default pref.

This reverts commit 80b06cdf.

This is the first release in the 1.9.4 series. We switched to this new
series to avoid the confusion between maint-1.9.3 and non-maintenance
1.9.3 releases.

To keep the browser.startup.homepage pref value out of translators
hands, all of the localized browser.properties files have been
removed and the pref value (about:tor) has been moved to a new
non-localized.properties file.

We no longer provide a value for spellchecker.dictionary, which
means non en-US users will probably need to set their spellchecking
language from the browser context menu or via about:config after
they install a dictionary for their language. The browser will also
consult the LANG environment variable and use a "default default"
of en-US if an en-US dictionary is installed.

Avoid hard-coded heights and positions in about:tor. The "update needed"
  arrow is now constructed from 4 elements instead of 2 and the info.
  "bubbles" use table layout instead of hard-coded heights.
Set the CSS z-index so that text will be in front of the status image
  (onion image) and the "update needed" arrow.
Use "let" instead of "var" in the about:tor JS code.

We previously spoofed the `intl.accept_languages` value to "en-us, en"
but with the update to ESR 38 Firefox does not like the lower case
country code anymore. See: https://html5.org/r/8458 and
https://bugzilla.mozilla.org/show_bug.cgi?id=889335 for the reasons
behind that.

We adapt our code accordingly and set the default value to "en-US, en"
now. This fixes #13277 as well.

Thanks for this patch, cypherpunk.

Adding this fixes problems such as the lack of "Tor Browser"
in the left side of the URL bar for pages such as about:config.

This reverts commit 495c0079.

This reverts commit edeaca15.

This fixes 16722 as well and resets the toolbar UI to kill
"Share this page", but that still requires another restart :/.

This is basically Mike's idea and code.

Account for an nsIExternalHelperAppService.idl interface change
(the parameters to the doContent() method were changed between
ESR31 and ESR38). See Mozilla bug #903022.

Patch by Pearl Crescent

Import aboutDialog.dtd and aboutTor.properties from Transifex.
Improved import-translations.sh to check that all .dtd and
  .properties files are imported.
Work around a Transifex issue that caused some entities to be
  encoded twice.

Check the state of the active update (if any) and open the update prompt
in the correct mode.

It is now obsolete. Firefox now properly disables session store if private
browsing mode is enabled.

We avoid using https://127.0.0.1 as update URL in order to omit scary
Tor warnings (see: #13129).
