I am no longer able to open in Mac Preview or save when hitting Command + P, then 'print using system dialog'. It will only print instead. For instance, I save certain web pages as PDFs using the print dialog and now it will only print when trying to use either the save or preview options. Command + P, print using system dialog, then I choose either save as PDF or open in Mac Preview, but as soon as I do one of these it will only print. I am able to use save in the drop-down list of printers, but I need to be able to open in Mac Preview.

Hi,

I added some annotations to a PDF using Okular on CachyOS. When I open the PDF in Chromium’s built-in PDF viewer, the annotations appear in the correct positions, just as they do in Okular. I also checked using a few online PDF viewers, and the annotations display correctly there too.

However, when I open the PDF in Firefox, all the annotations appear in different positions than they do in Okular.

I'm having a problem with Firefox when opening PDF files. The electronic signature appears inaccurately, making it difficult to complete tasks using that signature. Please improve the quality of the simple electronic signature and make it more accurate so I can finish my remaining work.

I am a magazine editor right on deadline and as my Firefox inisted it must be updated I endeavoured to do so and now it will nor allow me to open up and forward any pdfs.Please help.

Hi, I have few laminating machines icons on my computer face but I can't open them there is a message saying I can't open this file,

I think I have a Firefox PDF reader on my computer.

Thank you Bob Robertson

Firefox 136.0.1, Linux 6.8.0-55, have set Okular as default pdf application, however Firefox will not open pdf file when downloaded nor will it open the file when selecting Open File from the Download Icon on the toolbar. Only was I can get to file is to select Show in Folder option and open from within Dolphin.

In Firefox, recently I am unable to download pdf documents. I get the message "download failed". If I request the same download using Chrome, I get the download immediately. But Firefox is my default browser and it's a nuisance. This only started in the past month or so.

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

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.
