+
+cert-error-mitm-connection = { -brand-short-name } notar CA-vottunarstöð Mozilla til þess að staðfesta öryggi tengingar, frekar en að styðjast við skilríki í stýrikerfi notandans.

+# LOCALIZATION NOTE:
+# Strings here are used to create events and tasks with start and end times
+# based on email content.
+# None of the strings are displayed in the user interface.
+#
+# You don't have to fill all from.*, until.*, *.prefix and *.suffix patterns.
+# It's ok to leave some empty.
+# Please consider declensions and gender if your language has them.
+# Don't just translate directly. The number of variants doesn't have to be
+# the same as in en-US. All of 0, 1, 2, etc is allowed in patterns except alphabet
+# pattern. You can and should add language specific variants.
+#
+# There are two different ways to find a start time text in email:
+# 1) it matches a from.* pattern and does not have end.prefix or end.suffix next to it
+# 2) it matches until.* pattern and has start.prefix or start.suffix next to it
+# Similar inverse logic applies to end times.
+# These rules enable using prefix and suffix values with only start.* or only until.*
+# patterns localized for some languages and thus not having to repeat the same
+# values in both.
+#
+# Patterns are partially space-insensitive.
+# "deadline is" pattern will find both "deadlineis" and "deadline  is"
+# but "deadlineis" won't find "deadline is" or "deadline  is".
+# Therefore you should include all spaces that are valid within a pattern.

+# In case you are looking for the note about different declensions on date
+# formats, here it is. If your language doesn't use different declensions of
+# month names, you shouldn't have much work. Just leave the *.monthFormat
+# string on "nominative" and the string month.*.name will be filled in.
+#
+# If you need a different form for a string, you can change the 
+# *.monthFormat to a different value. Supported values are currently:
+#    nominative (default), genitive
+# The modified month name form will then be filled in accordingly. If this
+# system does not suit your needs, please file a bug!

+# any ordinal symbol for the monthday number:
+#   dayHeaderLabel, monthlyDaysOfNth_day,
+#   yearlyNthOn, daysIntervalBetweenYears,
+#   daysIntervalBetweenMonths, daysIntervalInMonth.
+# Write only a single string if the ordinal symbol is the same for every monthday, otherwise

+# If your language doesn't require that in the mentioned strings, leave it empty.
+# e.g.
+# dayOrdinalSymbol=.

Einnig gæti verið að póstinum hafi verið breytt á meðan sendingu stóð. Hinsvegar er mjög ólíklegt að annaðhvort af þessu hafi gerst.\n

+SIInvalidHeader=Pósturinn inniheldur rafræna undirskrift, en undirskriftin er ógild.
+SIContentAltered=Rafræn undirskrift þessa pósts passar ekki við meginmál póstsins. Svo virðist sem póstinum hafi verið breytt eftir að sendandi bætti við undirskriftinni. Þú ættir ekki að treysta á efni þessa pósts fyrr en þú getur staðfest efni hans með sendandanum.

+SIRevoked=Skilríkið sem var notað fyrir rafræna undirskrift þessa pósts hefur verið afturkallað. Þú ættir ekki að treysta á efni þessa pósts fyrr en þú getur staðfest efni hans með sendandanum.

+SIPartiallyValidHeader=Jafnvel þótt rafræna undirskriftin sé gild, er ekki vitað hvort sendandi og undirskrift sé sama persónan.
+SIHeaderMismatch=Tölvupóstfangið sem er skilgreint í rafrænu undirskriftinni er öðruvísi en tölvupóstfangið sem var notað í póstinum. Athugaðu upplýsingarnar í rafrænu undirskriftinni til að sjá hvaða persóna það er sem er með rafrænu undirskriftina.

+pop3AuthChangeEncryptToPlainSSL=POP3 þjónninn virðist ekki styðja dulkóðuð lykilorð.

+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 til að nota vörumerki eða hefur notkunarleyfi fyrir vörumerkjum frá Mozilla Foundation stofnunni eða öðrum aðilum, þar með talið án allra takmarkana Firefox-nafnið eða fyrirtækismerki þess. Meiri upplýsingar má sjá <a data-l10n-name="mozilla-trademarks-link">hér</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.
+rights-intro-point-4 = Hvernig meðferð persónuupplýsinga og upplýsingar sem eru sendar til { -vendor-short-name } með { -brand-short-name } er háttað er lýst í <a data-l10n-name="mozilla-privacy-policy-link">Meðferð persónuupplýsinga hjá { -brand-short-name }</a>.
+rights-intro-point-4-unbranded = Allar reglur um meðferð persónuupplýsinga fyrir þessa vöru ættu að birtast hér.
+rights-intro-point-5 = Sumir eiginleikar í { -brand-short-name } nota vefsvæðisupplýsingar, en, því miður getum við ekki ábyrgst að þær upplýsingar séu 100% nákvæmar eða villulausar. 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>.
+rights-intro-point-5-unbranded = Ef þessi vara inniheldur vefþjónustur, skulu allar viðeigandi skilmálar fyrir þjónustuna vera tengdar við <a data-l10n-name="mozilla-website-services-link">Vefsvæðisþjónustu</a> flipann.
+rights-intro-point-6 = Til að geta spilað sumar tegundir af myndefni, þarf { -brand-short-name } að hala niður ákveðnum tegundum af afkóðunarviðbótum frá utanaðkomandi aðilum.
+rights-webservices-header = { -brand-full-name } Vefupplýsingaþjónustur
+rights-webservices2 =
+    { -brand-full-name } notar vefupplýsingaþjónustur ("Þjónustur") til að bjóða 
+    upp á suma þá eiginleika sem aðgengilegir eru í þessari útgáfu af { -brand-short-name } 
+    eins og lýst er hér fyrir neðan. 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>. 
+    Aðrar stillingar og þjónustur er hægt að gera óvirkar í valkostum.

+rights-locationawarebrowsing-term-4 = Staðsetningarvöfrun er núna óvirk

Hinsvegar, geta þeir ekki ábyrgst að þessar upplýsingar séu alhliða eða réttar.  Sem dæmi, gæti örugg vöfrun ekki endilega borið kennsl á óörugg vefsvæði og sum vefsvæði gætu verið rangt skilgreind sem örugg, og einnig eru staðsetningar frá staðsetningar þjónustunni bara ágiskanir og við eða þjónustuaðilar okkar geta ekki borið ábyrgð á að staðsetningar sem veittar eru séu nákvæmar.
+rights-webservices-term-2 = { -vendor-short-name } hefur leyfi til að stöðva eða breyta þjónustunum að eigin geðþótta.

Þessir skilmálar takmarka ekki nein réttindi sem eru leyfð með opnum hugbúnaði sem á við { -brand-short-name } og samsvarandi útgáfur af frumkóða { -brand-short-name }.

+    Sum lögsagnarumdæmi leyfa ekki útilokanir eða takmarkanir á ákveðinni 
+    ábyrgð, þannig að þessi fyrirvari gæti ekki átt við þig.</strong>

Ef einhver hluti þessara skilmála telst vera ógildur eða er ekki framfylgjanlegur, munu samt sem áður aðrir skilmálar vera áfram virkir.

+# 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

+# to provide and in what order.

+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.

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.
