I've been using the firefox pdf viewer for quite some time and it's worked quite well. Within the last few days though I've developed an issue.

When I open a pdf it opens correctly for just a brief second (standard text, white background, nothing unusual) and then switches to something like the attached image (black background/ text and such). I have not changed anything that I'm aware of, though I did just recently install a new firefox update (136.0 64-bit windows 11). I didn't notice any articles or comments about this particular issue here yet, so figured I'd ask for some help.

Anyone know how to resolve this? Or other things I should look into?

Thanks for your time, Derek

Unfortunately, my workflow involves dealing with multiple PDF files per day. However, for some reason, Firefox's behavior with regards to PDF files is inconsistent.

• If I set the Action to Save File, Firefox downloads all PDF files, including those that it can normally open in the browser when I click a link (e.g. files hosted in servers that allow direct access to PDF files). As such, my Downloads folder is cluttered and needs to be cleaned regularly to delete the PDF files that were downloaded even if I could have opened them in the browser.
• If I set the Action to Open in Firefox, Firefox can now open those hosted PDF files in the browser instead of downloading them to disk. However, every time I download a file, Firefox then opens the file in Firefox after downloading, even though I need to edit the PDF file somewhere else.

Would it be possible to set Firefox's behavior so that it does BOTH of these things:

1. Open PDF files that can be opened in the browser without downloading in Firefox without needing to be downloaded, AND
2. Do not open downloaded PDF files in Firefox after downloading is complete.

Hi. I like using Firefox, But when I open a PDF or download a document for PDF reading I continually encounter a problem which seriously interferes with reading the document with the PDF. The Problem is this - PDF Is unusable because of a box that appears on the right side of PDF. The box contains an animation of a highlighter continually highlighting a representation of text. How do I make this box go away and stay away so I can read the PDF? Thank you for any help you can provide to solve this issue. Sincerely W.

When I open a PDF in Firefox, a box covers the right half the page demonstrating the highlighter tool. It never leaves. It blocks half the page and prevents me from reading and/or printing. Please help. It's making my work impossible.

when opening a PDF in firefox an auto dialog box comes up saying "now you can highlight your PDF's" with a highlighter symbol showing how its done.this ad is blocking my document and I can't seem to remove this ad box> how can I fix this and remove this

Hi, Up to the most recent update of Firefox I could preview PDFs within a cloud based software, but when I downloaded them they opened up in my default PDF Viewer.

Since the update the preview PDFs in the software just spin and never show, unless I have the setting in Firefox set to "open in Firefox" then I can see them. But if I have that set, then any PDF I try to open or download will open in a new Tab in Firefox, rather than the PDF viewer, and then I have to save it to be able to open it in the PDF viewer.

However, if I change the setting to be "Use Windows Default Application" they open up just fine in the PDF viewer, but the previews in the cloud based software go back to spinning and not opening.

How do I get back to having both things happen, rather than either / or please?

Many thanks for any help offered Best regards Jen

On my home page i have 2 rows of short cuts. Then the latest news listings. Can I change the types of news listings? For example one story might be from NPR while the next can be from CNN then another from MSNBC. Non of which interests me. Is there away to set sites in the settings to list News and events that I would be interested in? Sites like The Wire, Reuters, NewsMax, RT, The National Desk, etc. So would there be a way to get those headlines? Thanks

So when I read and edit documents (PDFs), I need to manually select the highlighter and other tools, and it is very painful and tedious. Also, there is no option for different modes, such as solarized mode, and I need to install extensions, which are not compatible as well. Now is there any way to enable and fix these?

a few months ago firefox started rendering images funky. I am not sure what changed, it seems to be a setting problem as other computers with FF 135 don't seem to do this. I have not been able to come up with the right search terms to describe the problem. here is a screen shot of the issue.

When I am using the highlight tool in my firefox browser, the drop-down stays open and there appears to be no way to make it invisible. It takes up a chunk of my browser window so that I can't read the part of the pdf it's covering. Is there a way to make it go away while I am continuing to highlight in my pdf?

As long as I have legitimate antimalware running, even with exceptions added for firefox, almost every single page comes up with one of the unique-to-firefox security errors rendering it practically useless. And the recommendation is to disable my antimalware? This is not an acceptable solution. I certainly don't trust Firefox to call the shots regarding my security over a reputable antimalware company. Especially when firefox is the only browser that has a problem. If you're going to to make yourself useless, you might as well let me access a page with a valid certificate and signature. Can we have an option to turn off your faulty security measures please?
