How come websites aren't taking up the entire window?

Closed this issue 3 years ago · 5 comments

For some reason websites only take up around 90% of the space of the window. But I want them to take up the entire window like they would in every other web browser. How can I change it to do that. It's probably something in the about:config section, but I don't know what.

This is most likely an anti-fingerprinting measure which makes sure that browser window size is nothing out of the ordinary. privacy.resistFingerprinting is the value in question.

Okay. I am going to set privacy.resistFingerprinting to false and replace it with a fingerprint blocking add-on. If that solves the issue, I will close this issue.

Unfortunately turning off privacy.resistFingerprinting didn't do anything, even after restarting the browser.

letterboxing is (currently) independent of RFP

user_pref("privacy.resistFingerprinting.letterboxing", true); // [HIDDEN PREF]

edit; you want to reset that or modify it to false

Does that solve your issue @amarakon ?
