Firefox Community Forum

I have uninstalled Adobe Acrobat from my Mac Mini running Sequoia OS. Acrobat is not listed in my Firefox extensions. Yet, when I open a PDF from a link in an email, it opens in Acrobat (clearly announced as such with its logo) in a Firefox tab. Also, I have my Firefox setting for PDF files set to "Open in Firefox".

Acrobat is a vicious plague on my life, and I want it gone. Please assist me in ridding it from my Firefox use.

Thank you, Tom

Hi All,

I've set Firefox to open PDFs in the default system application (I'm on Linux, KDE, Firefox 146). With previous versions it worked fine. Now, it won't open the file; instead it shows a popup that I have to click to open the file.

Is there a setting I can tweak to get the old behavior back?

Thanks

When I load a pdf into Firefox, a pdf app opens at the top so I can write text, add an image, etc (thanks for this). Lately, when I am using the app, it will stop working randomly no matter which button I am using. If I'm suing text, it will stop and not allow me to select anything. If I'm using the highlighter, the same thing happens. I tried removing all my extensions but that did not work. I know this started after a Microsoft and Firefox update. Could you please fix it, otherwise I have to use Chrome and I hate Chrome. The app controls are on the far right of the image.

I'm begining to regret installing v146.0!

One of the most useful features of Firefox is the PDF editor and with this update, I've found that after annotating a PDF with several text boxes, clicking the text box icon (as shown in the attached screenshot) does absolutely nothing and it is impossible to enter any further text. The only way out of this is to refresh the pdf (after saving otherwise all changes will be lost) and then starting all over again only for the error to repeat itself making the editor almost unusable. Would really appreciate knowing how to work around this especially since to make my notes clearer, I change the color and the font size which is all lost everytime I have to refresh the PDF :-(

Incidentally, why are there so many updates? I prefer stable software that works rather than 'new features' that I never use!

Finally, Firefox used to have an amazing facility of making the Firefox private browser the default browser for Windows 10 but this was removed some years ago and can only be reinstated by changing registry keys. Everytime there's an update, these registry keys are overwritten :-(. Why was such a useful feature removed please?

Thanks in advance.

When a PDF document is dragged into Firefox, you get an app that allows you to write on it, import images, highlight, etc. However, if I use grouped tabs, you cannot use the app anymore. It will not write on grouped. I'm not sure where this issue would fit in the options provided. Thanks for any help you can give.

Certain PDFs only allow page view when opened in Firefox. When opened with other PDF viewing software or browsers (Microsoft Edge, Adobe Acrobat, Google Chrome), these PDFs allow continuous scrolling. I don't have this issue for most PDFs.

I've tried fixing the problem by editing the PDF settings in Adobe Acrobat but to no avail. When combining a PDF that works fine with a PDF that doesn't allow continuous scrolling in Firefox, it seems to take on the settings of not allowing continuous scrolling.

Hello! I have a lot of PDFs on my computer, and every time I go to look at them, my browser immediately views it in "automatic zoom" and with the sidebar expanded. Is there a way to disable these features? I find myself fixing all the PDFs to "actual size" and closing the sidebar, and not only does it take a lot of time, but it doesn't save my preference once I've closed and reopened it! Please let me know if there's a setting I can disable to fix this issue. Thanks!

Trying to read PDF pages in Firefox. When I click on a file it says "You do not have OpenText Content Server Browser Web Extension 2.0.10 installed, or it is not enabled. Follow these instructions to install and enable the extension." I've looked in the extension add ons but cannot find the appropriate add-on and when I go to download from file, there are no files that would are appropriate either. Any suggestions? Also, I'm using a federal government laptop if that has anything to do with it.

Thanks guys for any help you can offer....

I’d like to give some feedback regarding the built-in PDF editor. I really enjoy this feature and use it often because it’s convenient and easy to work with. However, there’s an issue that has forced me to stop using it for now.

Whenever I add text to a PDF using Firefox’s editor, everything looks fine on my computer. But once I upload the edited PDF to another platform such as Google Drive, the text I typed disappears and turns into empty boxes. This means the annotations or filled-in fields are no longer readable on other devices or cloud services.

At the moment, the edited PDF can only be viewed properly on my own computer, and this limitation makes it difficult to share documents or submit forms. I sincerely hope this compatibility issue can be improved, because I really do love Firefox’s PDF editing feature and would like to continue using it.

Thank you for your work, and I hope the team can look into this problem!

I frequently use the firefox pdf viewer and greatly appreciate it. However when I use the highlight tool the large popup is distracting and covers up some of the contents on the page. Is it possible to have the tool selected and use it without having the popup being constantly open. See attached image

In the PDF editor, when I select a tool, for instance, "Highlight" or "Text" or "Draw", from the top bar (right corner), to "unselect" it and go back to the hand tool I have to press the button in the toolbar again.

Is there not a keyboard shortcut?

I expected that "Escape" would unselect the tool.

Hello, how can I preset a fixed size for opening and displaying PDF files? Ideally, I'd like to be able to select a percentage scale or permanently set a fixed height or width. Thank you for your help.

Hallo, wie kann ich eine feste Größe für das Öffnen und Anzeigen von PDF-Dateien voreinstellen. Bevorzugt wäre z.B. eine Skalierung in % vorzuwählen oder auf Höhe bzw. Breite dauerhaft fest voreinzustellen. Danke für Ihre Unterstützung

Hi all, I remember in older versions of Firefox (within the past 6 months) that pdfs embedded in a page would be a hyperlink that you had to click which would open in another tab. Now pdfs automatically open which is very annoying as it makes it difficult to read, while I found a way to open it in another tab I was wondering if there is a setting I can disable so I can just click on a hyperlink.

Thanks in advance

Whenever I use FF to get a PDF file, It is corrupted. It seems to download ok. It will display, but copying from it yields garbage. Using apples Preview for speaking yileds jiberish. I do not have this problem with Safari

I had this problem for months even before my latest OS was install. Mac mini, M2, Sequoia 15.7.1, FF 145.0 (aarch64) kleps@uic.edu
