Anyone know how to get it to work? I tried doing what was suggested in viewtopic.php?f=70&t=30314&p=243697&hil ... rt#p243697, but it didn't work.

window.visualViewport is undefined

They are trying to use a mobile-centric (and Google-sourced) API without checking for support first.
I filed Issue #2714 (UXP) to implement what few readonly properties it is supposed to spit out but it would be useless to try and implement this entire API in UXP otherwise since we do not use mobile gestures, APZ or support whole-desktop-zooming as that is entirely something for small mobile devices which we don't support anyway.

If you have Greasemonkey here's a userscript to work around it; depending on your needs you may also be able to simply turn off Javascript, or block the "635" script.

Code: Select all

// ==UserScript==
// @name        Scribd visualViewport
// @namespace   adoxa
// @include     https://www.scribd.com/*
// @version     1
// @grant       none
// @run-at      document-start
// ==/UserScript==
window.visualViewport={scale:1,addEventListener:()=>{},removeEventListener:()=>{}}

If I were to change scribd in the GM script to the relevant site, would this also work for https://www.citygross.se/ & https://yep.com/ & https://stein.world/ ?

Off-topic:
Sadly, Visual Viewport is becoming more popular, and site devs/frameworks has lost the concept of fallback code. Just thinking to myself here, but it would be interesting too see if most of the problematic sites rely on the same, or same source, framework. https://survey.stackoverflow.co/2023/#m ... s-webframe

The larger majority of frameworks seems to come from or rely on google, meta, and microsoft.. googles deep vertical and even sometimes horizontal integration just can't be legal..! Not that current legislators even grasp the difference between chrome and chromium, or google search and frontends like startpage..

Rant over. Sorry

It worked for citygross & yep; I had no issues with stein.world. Just add the includes (and rename without "Scribd ").

Code: Select all

// @include     https://www.citygross.se/*
// @include     https://yep.com/*

Much appreciated, thanks!

Ah, yeah, Stein World has it when trying to log in. My bad. I'll try to add it as well and see.

Speaking of frameworks having become too complex to manage...

CVE-2025-29927 Severity:9.1
Impact

It is possible to bypass authorization checks within a Next.js application, if the authorization check occurs in middleware.

This can effectively be spoofed with the x-middleware-subrequest header sent from a client. "Trust me bro! I'm authorized!"
oopsie!

Yikes!

Also, Next.js is React.js(1) based, requiring a Node.js server(2), and Node.js runs on googles V8 javascript engine..
If I understand it right.

1. React.js being a Meta/Facebook product.
2. Or a Vercel server using Cloudflare.

Getting a similar blank-pages result on embedded Scribd content, but cannot say if it's related to visualViewport. Tried applying the above userscript with no result.

It seems to be a problem with the way it updates some styles (switching display from none to unset). Here's a userstyle to unset it explicitly.

Code: Select all

@-moz-document domain("www.scribd.com") {
  .ff0, .ff1, .ff2, .ff3, .ff4, .ff5 {
    display: unset;
  }
}

[back2themoon]

Thank you adoxa, also works on scribd.com.

edit: deleted some erroneous comments I made. All good!

[Moonchild]

This is now slated for 33.9.0, meaning at that time you should be able to do away with the workaround.
