Tor Browser: How to remove letterboxing, the black/gray bars in Tor Browser 🧅

in STEMGeeks2 months ago

So entfernt ihr im Tor Browser das Letterboxing, die schwarzen / grauen Balken.

Der Tor Browser ist der Browser der Wahl, wenn ihr im Internet wirklich anonym surfen möchtet.

Doch es gibt ein Feature, das mich eher stört und das ist die fixe Fenstergröße bzw. das Letterboxing, wie es offiziell genannt wird.

Um das Fingerprinting des Browsers zu erschweren, nutzt der Tor Browser normalerweise nicht das ganze Fenster, sondern rundet das Fenster auf eine standardisierte Größe, damit man von der Fenstergröße (Viewport) nicht so einfach auf das verwendete Device schließen kann.

Nebeneffekt ist, dass der Viewport eben nicht das ganze Fenster nutzt und schwarze (bzw. weiße) Balken entstehen, ähnlich wie bei Kinofilmen, die man auf einem 16:9 Monitor schaut.

Um die schwarzen Balken zu entfernen, gibt es aber ein Flag in den Einstellung, das ihr ändern könnt.

So entfernt ihr das Letterboxing im Tor Browser

  1. about:config öffnen (in der Adresszeile zu "about:config" navigieren)
  2. Warnung bestätigen (Accept Risk and Continue)
  3. nach der Einstellung "letterboxing" suchen und Einstellung privacy.resistFingerprinting.letterboxing auf false setzen.

Violá! Jetzt verwendet der Tor Browser das gesamte Fenster. Allerdings seid ihr damit etwas leichter trackbar. Ob ihr dieses Risiko eingehen wollt, müsst ihr je nach Nutzung selbst abwägen.

Verwendet ihr den Tor Browser? Habt ihr das Letterboxing aktiviert oder deaktiviert?


How to remove letterboxing, the black/gray bars in Tor Browser


The Tor Browser is the browser of choice if you really want to surf the Internet anonymously.

But there is one feature that rather bothers me and that is the fixed window size or letterboxing, as it is officially called.

In order to make fingerprinting of the browser more difficult, the Tor Browser normally doesn't use the whole window, but rounds the window to a standardized size, so that one can't easily infer the device you're using from the window size (viewport).

A side effect is that the viewport does not use the whole window and black (or white) bars appear, similar to what happens when you watch a movie on a 16:9 monitor.

Howerver, to remove the black bars, there is a flag in the settings that you can change.

How to remove the letterboxing in the Tor browser

  1. open about:config (navigate to "about:config" in the address bar)
  2. accept the warning (Accept Risk and Continue)
  3. look for the setting "letterboxing" and set the setting privacy.resistFingerprinting.letterboxing to false.

Violá! Now the Tor Browser will use the whole window. However, this makes you a bit easier to track. You have to decide for yourself, whether you want to take that risk, depending on your usage and privacy needs.

Do you use the Tor Browser? Do you have letterboxing enabled or disabled?

Da ich den Tor Browser nicht benutze (würde ich vermutlich öfter, wenn es nicht so träge wäre) habe ich auch kein letter boxing. Trotzdem ist das sicher für viele hilfreich!

This is really nice and helpful, thanks for sharing the steps in removing it.

I'm gonna file this under my "no idea when I'll use it, but good to know" folder.

Yeah, it's one of the first settings I change when I install the TOR browser, like to have it full screen without the black bars, even if it becomes less anonymous then.

Few are browsers that guarantee complete confidentiality when surfing Internet. Thanks for your instructions.

yea, that could be annoying, nice fix.. 😎

i don't use Tor all the time, but have before.

I don't really use Tor because I don't really know if it's the best place to go to because of all the dangers. At least, I don't really risk it but I know about Tor from a few videos that I have seen about it.
