ESR115: change devicePixelRatio spoof to 2 in alpha for testing

links

• https://github.com/mullvad/mullvad-browser/issues/75 - Blurry elements on some websites
• 1554751 - Consider to change the spoof value of window.devicePixelRatio

then upstream if no issues reported .. I think 4 years is long enough. It's literally a single char change. Good first patch

added All Platforms Fingerprinting FF115-esr labels

note: some PDF code lives here as well, but I think PDFs are/were supposed to be exempted (since they couldn't exfil anything .. until they had some limited JS added, which we disable)

added Backlog label

added Feature label

LW leading the way ... https://codeberg.org/librewolf/issues/issues/1571

IMO we can just do this, return 2 - simple as changing the value in code. And patch -moz-device-pixel-ratio in a follow up for 13.5. At least this gives us 1 release in alpha should we find weirdness

@richard cc: @ruihildt

added 13.0 stable label

@thorin if someone writes/ports the patch happy to review otherwise this is going to have to wait after our must-haves for 13.0

sounds like a job for @cypherpunks1 :) or fabrizio - just change the value, we can open a new ticket to cover the -moz leak for followup

oh you should have tagged me, I would have been happy to offer the patch :-)

removed 13.0 stable label

added 13.5 stable label

added Roadmap::Future label and removed Backlog label
