When Fidefox updated to 157, it kept all my settings, but it will not allow my windows default PDF viewer to save and open PDFs automatically. Instead, it uses the Firefox PDF viewer - which has improved, but it is not what I would like. I have reset my handlers.json along with trying to force it via about:config. Nothing is working, and it is a hassle.

Why isn't this happening when I open PDF files? Usually, there's an option that lets me choose between opening it directly in Firefox or using my PC's default app (Foxit Reader), but it keeps opening directly in Firefox instead.

Meine gespeicherte PDF Dateien lassen sich nicht mehr automatisch mit Firefox öffnen Durch das Umstellen Ihres Firefox lassen sich die am Computer gespeicherten PDF nicht mehr automatisch mit Firefox öffnen. Ich werde jedes Mal gefragt, womit geöffnet werden soll.

Hi. This is more of a bug report than a question, but after new update our company got a big problem: we print from firefox, but we had it set up so as we open the PDF document it would open directly into Adobe Reader (and then print). After update this is no longer available, altough the settings say clearly "open with Adobe/windows application". Is there a possible solution? Thanks for the answer

I used Quickfile for my accounts. Until the most recent Firefox update, I could create invoices within the software which seems to use Firefox to create them. this no longer works - within firefox it looks like it is creating the file, but doesn't seem to create a file that is able to be opened. Therefore I am using the Print Preview within Firefox, and selecting Print/Save to PDF and this works ok, but is another couple of clicks which is annoying.

Whilst Firefox may not be at fault, the issue isn't there on other browsers and it happened with the big update last week.

The "New" PDF previewer sucks, can we revert to the old one that actually worked ?! It's a "Preview" , maybe don't try to open everything and BE a PDF program inside the browser, the whole point is to get a "Quick" look so you can decide to open , or, delete it ! This is as Bad as MS Edge trying to take over for PDF's , Revert this change, or Give us a way to choose to use the old way ! Thank you.

Ich öffne ein PDF File in Firefox. Er wird in Firefox angezeigt und sofort öffnet sich die Datei zusätzlich Adobe Acrobat. Das soll es nicht. Ich habe geändert: - in firefox im Menu download: PDF öffnen: Firefox - in Windows 11 Standard APP für PDF: Firefox - in Windows 11 Standard Browser: Firefox

Ich weiss nicht, wo ich jetzt noch die Einstellungen ändern kann, damit sich eine PDF Datei nur in Firefox öffnet und nicht automatisch nochmal Acrobat.

I use Firefox to read a lot of PDFs. Some of the documents have their own internal sections embedded into them. Because of this, Firefox PDF organizes the page numbers in a strange way. Instead of just page 1 through page 112, each section will have its own numbers starting over from 1. Thus, when I try to skip to page 3, it doesn't actually bring me to page 3 of the entire document, it brings me to page 3 of whatever section I'm in.

A large part of my job is digging through documents, and I don't have time to try and figure out which section of the document I'm in. I need page 3 to be the actual page 3. And I refuse to go back to Edge or Adobe.

I know there's a way to fix this in about:config because I've done it before on a previous computer, but I recently got a new computer and all my settings are gone. How to I turn on just regular page numbers in about:config?
