+# LOCALIZATION NOTE (intl.accept_languages):
+# This is a comma-separated list of valid BCP 47 language tags.
+#
+# Begin with the value of 'general.useragent.locale'. Next, include language
+# tags for other languages that you expect most users of your locale to be
+# able to speak, so that their browsing experience degrades gracefully if
+# content is not available in their primary language.
+#
+# It is recommended that you include "en-US, en" at the end of the list as a
+# last resort. However, if you know that users of your locale would prefer a
+# different variety of English, or if they are not likely to understand
+# English at all, you may opt to include a different English language tag, or
+# to exclude English altogether.
+#
+# For example, the Breton [br] locale might consider including French and
+# British English in their list, since those languages are commonly spoken in
+# the same area as Breton:
+# intl.accept_languages=br, fr-FR, fr, en-GB, en
+intl.accept_languages=is, en-us, en
+
+# LOCALIZATION NOTE (font.language.group):
+# This preference controls the initial setting of the language drop-down menu
+# in the Content > Fonts & Colors > Advanced preference panel.
+#
+# Set it to the value of one of the menuitems in the "selectLangs" menulist in
+# http://dxr.mozilla.org/mozilla-central/source/browser/components/preferences/fonts.xul
+font.language.group=x-western
+
+# LOCALIZATION NOTE (pluralRule): Pick the appropriate plural rule for your
+# language. This will determine how many plural forms of a word you will need
+# to provide and in what order.
+# See: http://developer.mozilla.org/en/docs/Localization_and_Plurals
+pluralRule=15
+
+# LOCALIZATION NOTE (intl.menuitems.alwaysappendaccesskeys, intl.menuitems.insertseparatorbeforeaccesskeys):
+# Valid values are: true, false, <empty string>
+# Missing preference or empty value equals false.

+#                     the prevalent kind of keyboard for your target user.
+# LOCALIZATION NOTE : There are two types of keys, those w/ text on their labels

+# For more information please see bugzilla bug 90888.

+# F11..F20 might be something else, but are really keyboard specific and not region/language specific
+# there are actually two different F11/F12 keys, I don't know which one these labels represent.
+# eg, F13..F20 on a sparc keyboard are labeled Props, Again .. Find, Cut

+rights-title = Um þín réttindi
+rights-intro = { -brand-full-name } er frjáls og opinn hugbúnaður, búinn til af samfélagi sem samanstendur af þúsundum allstaðar úr heiminum. Hér eru nokkrir hlutir sem þú ættir að vita:
+rights-intro-point-1 = { -brand-short-name } er á boðstólum fyrir þig samkvæmt skilmálum <a data-l10n-name="mozilla-public-license-link">Mozilla Public License</a>. Þetta þýðir að þú mátt nota, afrita og dreifa { -brand-short-name } til annarra.  Þú mátt einnig breyta frumkóða { -brand-short-name } hvernig sem þér hentar. Mozilla Public License gefur þér einnig rétt til að dreifa breyttum útgáfum.
+rights-intro-point-2 =
+    Þú hefur ekki leyfi ti lað nota vörumerki eða hefur leyfi fyrir vörumerkjum 
+    frá Mozilla stofnunni eða öðrum aðilum, innifelur það í sér án allra takmarkana 
+    Firefox-nafnið eða fyrirtækismerki. Meiri upplýsingar fást á <a data-l10n-name="mozilla-trademarks-link">hérna</a>.
+rights-intro-point-3 = Sumir eiginleikar í { -brand-short-name }, eins og t.d. að tilkynna hrun, gefur þér tækifæri á að senda tilkynningu til { -vendor-short-name }. Með því að velja að senda tilkynningu, gefurðu { -vendor-short-name } leyfi til að nota tilkynninguna til að laga vörur sínar, og leyfi til að birta tilkynninguna á vefsvæðum sínum, og að deila tilkynningunni.

Fyrir meiri upplýsingar, og meðal annars upplýsingar um hvernig á að gera þjónusturnar óvirkar, er að finna í <a data-l10n-name="mozilla-service-terms-link">þjónustuskilmálum</a>.

Ef þú vilt ekki nota þjónusturnar eða skilmálarnir eru óaðgengilegir, geturðu gert eiginleikana eða þjónustuna óvirka. Leiðbeiningar fyrir að hætta að nota ákveðinn eiginleika eða þjónustu er hægt að finna <a data-l10n-name="mozilla-disable-service-link">hérna</a>.

Sem dæmi, gæti öruggt vafur ekki endilega borið kennsl á óörugg vefsvæði og sum vefsvæði gætu verið rangt skilgreind sem örugg, og einnig eru staðsetningar frá staðsetningarþjónustum bara ágiskanir, auk þess sem við eða netþjónustuaðilar okkar geta ekki borið ábyrgð á að staðsetningar sem veittar eru séu nákvæmar.
