Dark mode for Embedded pdf Viewer

[dpa]

Hello everyone...

I use Firefox a lot of years and i am very happy with the interface.

But i saw that there is no built-in option to change  the Mode of Embedded PDF Viewer in to Dark

Is possible to be implemented in the near Future...?

Thanks in advanced.

I have a condition that makes it difficult and painful to read black on white and because it's hard to find a PDF reader on PC that has an invert colors feature, I have to read everything on my phone.

I hope Mozilla will one day make Firefox accessible to people with disabilities.

@1neStaryou can enable High Contrast Mode to achieve what you ask (https://mzl.la/3NOcnwM).

Thanks @Fristender - it worked for me too.

I use Firefox a lot to read PDF documents. Firefox contrast control mode with custom settings helps to change my PDF view to pitch black with white texts, which is perfect for me when viewing PDFS, but it makes all websites I visit very difficult to navigate and use. I'm requesting that there be an option to enable contrast mode for specific tabs or at least as an option when viewing PDF files.

Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.

@I_Nduefuna thanks for the feedback and request! There's a similar idea posted here: Dark mode for Embedded pdf Viewer 

If that aligns with your request, we can merge the two threads together and combine votes - that way the conversation is focused in one space. Just let me know 😃

Dark/Night mode for in-browser PDF reader?

Greetings,

We already have an extension for toggling dark-mode in Firefox. But these extensions don't work in the built-in browser pdf reader. Can we please have that option available for pdf? 

Thank you.

@mozzer That worked really well, thanks!
As a side note, I asked ChatGPT to create a toggle-able version of your bookmarklet. Here it is if anyone wants it:

javascript:(()=>{
const el = window.PDFViewerApplication?.pdfViewer?.container;
if(!el) return;
el.style.filter = el.style.filter ? "" : "invert(85%) grayscale(0)";
})();

I'm brand new to Firefox and I'm used to being able to enable the Dark Reader extension for PDFs in Chromium based browsers, so this page was really helpful. Thanks!

hello. sorry for the late reply. I'd be glad if the two post be merged
