Details

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:112.0) Gecko/20100101 Firefox/112.0

Steps to reproduce:

  1. about:config
  2. privacy.resistFingerPrinting - set to true
  3. restart brownser

Actual results:

The browser will not remember the previous window size, or font sizes ( set through ctrl + ) when I restart the browser.

Doing so while having privacy.resistFingerPrinting set to true should be possible.

The Dolphin-antic browser does both.

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Gtk' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Summary: Window Size and Font Size not Remembered with Finger Print Protection Turned On → privacy.resistFingerprinting works: Window Size and Font Size not Remembered

previous window size

RFP, by design, will not create new windows maximized, it will create them windowed so the viewport is in some rounded size from 1000 x 1000 and under

or font sizes ( set through ctrl + )

RFP, by design, does not respect site preferences for zoom settings. It allows you to zoom a tab, but resets on new tabs and new eTLD+1's

tjr, can we close this?

The Dolphin browser WANTS your profile to be fingerprinted, so that sites will be convinced that one profile is different than another profile with a different fingerprint. From their site:

Real fingerprint browser profiles

You'll look like a usual internet user as much as possible. We collect fingerprints from real users and give them to you when you create new browser profile.

This is the opposite of what RFP is trying to do: make everyone look the same. Completely different intent!

Perhaps what you want instead is to use our Multi-Account Container extension (found at https://addons.mozilla.org) so you can create those separate profiles, and the sizes and such can be remembered per container.

For RFP it is completely intentional that window and font sizes not be remembered.
