I get an empty pdf viewer frame. Also the debugger shows the following error;

Uncaught TypeError: Promise.withResolvers is not a function

Is there some way to overcome this problem? a future release of firefox esr?

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.

Firefox 137.0.2 64 bit

I've recently set up on a new desktop running windows 11.

My previous setup had windows 10, but the same version of Firefox.

In the past, when building web pages in php, I'd always used Firefox to preview the html elements of pages offline. I've not used a testing server on Windows as I'd rather test the PHP elements on the live server. Firefox was just for testing the html / css design elements, which it worked very well for.

Now, on my new computer and windows 11, when I try to open a php page offline with Firefox I get a window asking me what to do with the file - "open with" or "save file". When I choose "open with" and choose Firefox, Firefox opens up another tab with the address of the file in the address bar, but no content below, and then another window pops up asking me what I want to do with the file. This goes on indeffinately if I keep clicking "open with". There's no issue with the files I'm trying to open as I can open the exact same files on my win 10 computer with the same Firefox version and the display just fine. What's going on?

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.

I was having an issue with pdfs on firefox; all my pdfs were showing up as black. To fix that, I refreshed firefox, which solved the problem just fine. Unfortunately, once I did all my extensions stopped working. The page looks like this.

For most of my extensions, I can just solve this by getting rid of them and adding them again, but if I do that for onetab I'd lose all my stored tabs. How can I get this back?

For about a week now, I have been unable to read any pdf document I download. The body of the document is completely black (that is black, not blank). When I go to save the document, it is saved as a black (unreadable) document. I have had to switch to using another browser in order to be able to download/save a readable pdf document. How can I fix this issue?

Mozilla/Firefox is my browser. Lately, every time I am on a website where I need to open a pdf document, like a bank statement I want to download, a pop-up appears that advises me to sign on the dotted line or anywhere and shows a little pen writing something. Underneath is this sentence: "Draw, type or upload your signature, then place it exactly where you want. Save your go-to signature for next time."

Where did that come from? It blocks my view of the document and if i try to capture it in a "screenshot" nothing appears. Is this a Mozilla/Firefox thing or a (Acrobat) pdf thing? And what can I do to stop it?

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?

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?

For the past YEAR or more, every time I choose to download a PDF (whether by saving a web page via file/print/save to PDF or by downloading an actual PDF via emailed link) my saved PDF has a padlock. I am forced to remove each padlock individually by adding 'users' under permissions. There is no way to do this for more than one file at a time.

This never used to happen in the past and I've made no changes to my PC or to my Firefox settings. I know it's a FF thing because if I save my own MS Word files to PDF there is no padlock.

Is there ANYTHING I can do to finally stop this and download PDFs without a padlock?

Thanks.
