Diễn đàn hỗ trợ Firefox

I am an academic. I use Canvas. When I am in Canvas and I try to open a document in it from Firefox, what I get are solid black pages. I do not have this problem with Canvas in Chrome or in Edge. I really don't want to use those Browsers. I actually have this problem with every PDF I try to open from all sites. This is a recent problem. But if I cannot correct it, I will have to use other Browsers.

See the attached image. This showed up when viewing PDFs. The highlighter demo can not be removed or turned off. I uninstalled Firefox, reinstalled, still there. Uninstalled Acrobat, the demo is still there.

Whenever I open up PDFs within the Firefox browser, they have a black background and the text and images do not appear. I can copy the text and images out of the pdf and into a word document and it works out fine. Also opening it up on other applications works out fine. Attached is what happens when I open up a known working pdf in Firefox. The browser version is the current version, 135.0.

this is supposed to have a QR code, but it does not load. I have attached a still screenshot below.

I also cannot upload images using Firefox to Messenger. The large purple image is a result of an upload, but it should be a picture of a woman saved from Krita.

I tried a setting called "Refresh Firefox" and that fixed it but only for less than a day. whats going on?

I am using Firefox version 136.0.1 and we have multiple PDFs that are password protected (please see attached screenshot from Adobe Acrobat).

When the PDFs are opened in Firefox, it allows the user to add annotation/text/draw which we do not want to happen hence we added restrictions to the PDF. It seems to me that Firefox does not respect the security added to the file. How can I restrict annotations to the PDF or at least require password when the user tries to add text to it?

The following viewers/editors ask for password before you can edit them (expeted): - Chrome - Edge - Adobe Acrobat Pro

Thank you.

Firefox 138.0.1, MacOS Monterey 12.3

PDF files: settings is set to "Always ask" (see attached) However, when I click on a PDF link, and get the dialog "Open With" is grayed out, and the only option available is "Save File" (see attached screenshot). (A few weeks or months ago it all worked correctly.)

Is there a way to get "Open" working again?

Every time I open a file that is downloaded the box showing info on the highlight tool comes up and then I have to hover over it and hit escape............I do not want it to open at all so how do I stop it..............

Hello all,

I know this feature is brand new and awesome! I have a question about the statement below from the FAQ.

What does the statement "When editing with Firefox, your documents generally stay on your local device" mean? I am just wondering about the "generally" portion.

I sometimes have to edit sensitive documents and want to make sure that this editor is a viable option. Will there be a prompt if the file has to be uploaded to a server?

Just some security concerns.

Thanks in advance for your help.

Is this an extension on the browser ? Do not see how it functions... Many Tks

Firefox is not rendering/displaying charts (e.g. on Etrade), some graphs, and embedded pdfs (ex. on TaxCaddy--cannot see pdf files embedded into the web page). When I use Chrome, the problem goes away. I'm running 136.0.4 (64-bit) on Windows 11.

What can i do to fix this?

When printing a PDF with custom page ranges, the footer text in the print preview (see image) does not match the actual page. As shown in the example image, if I want to print pages 2-16, the preview indicating page 4 is actually page 5.

So, if I want to print with a very custom range, such as 2-4, 6-10, 12-14, 16, it will be very confusing and will take longer to adjust.

And I also print custom ranges like this very often for daily tasks. I’m not sure if this is a bug or just a minor adjustment needed in Firefox’s coding. Thank you in advance for your help.

I'm viewing a pdf that seems to be made of stacked images. While viewing this pdf in firefox it has these black lines between images, as seen in attachment, these change slightly as I zoom in. These lines do not appear when viewing the pdf in brave, see other attachment.

Also, this happens both on my desktop and laptop that have very different firefox setups.

How can I fix this without fixing the pdf?

How could I even fix the pdf?

Every time I try to view a pdf file on Firefox I can view the file but in the lower right 1/4 of the screen I get a graphic of a page with shaded areas representing lines with writing on them. There is a type of pen cursor moving along the line.

This happens with different pdfs - from the internet and from my saved files. This doesn't happen on another computer with Firefox.

I've deleted and redownloaded Firefox an number of times, also tried troubleshoot mode - no improvement. Virus scanned, restarted a number of times.

Pdfs work on edge and chrome and reader with no problem.

I have a screenshot.

Any Ideas? Thanks

Your browser needs immediate attention! I have windows 11. When I visit websites via Firefox and click on a link that takes me to a document, a large pop-up on the lower right side of the screen appears blocking half the page and preventing me from downloading or printing it. The pop-up depicts a cartoon-letter with a highlighter pen traversing its cartoon-text, below which is an enthusiastic missive stating (and I quote): "Now you can highlight your PDFs! With our new highlighter tool, you can read and edit PDFs in one place." Because of this infernal nuisance, I cannot print or download web pages. This has been going on for WEEKS! (That pop-up is USEFUL?! Who thinx up this stuff??!!) Apparently you're having trouble fixing this problem ... I understand--I'll just use Edge or Chrome from now on. Sorry if I woke you.

Hi, when I work in Xero, the pdf documents will not open. Firefox is up to date and I have wiped all cookied and history. Is there anything else I need to do please?

Thanks Amanda

Hello Mozilla Support Team,

I have been using Firefox for a long time, and recently I upgraded my Windows system. Before the upgrade, I had set Firefox to open PDFs directly in a PDF Reader other than Firefox’s built-in PDF viewer, and it worked perfectly. However, after the upgrade, Firefox now shows the "Opening when completed" message and opens PDFs slowly, instead of opening them immediately in my chosen PDF Reader.

I have checked the settings, cleared the cache, refreshed Firefox, and even tested with other software, but the issue persists. The settings for handling PDFs are still the same, but they don't seem to work as they used to.

Can you please assist me in resolving this issue? Any help would be much appreciated.

Thank you
