Diễn đàn hỗ trợ Firefox

I am a Dropbox user. I have until recently been almost strictly a Google Chrome user. The PDF seamless behavior I have been seeing in Chrome is like this: 1. If I click on a search engine result for a PDF, I see the PDF opened in the browser. 2. If I click on Download at Dropbox, the PDF is downloaded to my PC.

On installing Firefox, the behavior I saw was like this: Whether I clicked on a search engine result or Download at Dropbox, I saw the PDF opened in my browser.

When I changed the Action for Portable Document Format (PDF) (application/pdf) and Portable Document Format (PDF) (application/binary)to "Save File", the PDF downloaded to my PC. But so did search engine links.

I seem to have fixed the issue by making my settings like this: 1. Action for Portable Document Format (PDF) (application/binary) to "Save File" 2. Action for Portable Document Format (PDF) (application/pdf) to "Open in Firefox"

Fingers crossed. ??? I was wondering why it wasn't set up this way on installation.

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.

Examples (these link to documents from a Florida public document database): Example 1 (made with Power PDF Create) Example 2 (made with Adobe PDF Library): https://depedms.dep.state.fl.us:443/Oculus/servlet/shell?command=getEntity&[guid=5.506115.1]&[profile=Cleanup_Remediation]

Edit: Firefox 145.0.2, Windows 11

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.

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!

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 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.

So i reinstalled my graphics driver yesterday, and after that when i open a pdf on firefox it only shows blackscreen. it didnt happen on other browsers(chrome, edge)

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

I often open PDF links in Firefox. I can choose to open the PDF in a Firefox tab. If I leave the tab open and restart my computer, or look for that tab sometime in the future, I often see a page that says File not found (see picture). Somehow the page is being cleared out of the cache. Not sure if Firefox is doing this, Windows or some other program. Any ideas to keep these pages so I can see them in the future?

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

I often save to PDF or mark text then transfer it into a document. Firefox renders many letter combinations as ligatures: ff, fi, ffi, fl, and more. I don't want ligatures. The cures proposed have involved forbidding pages to use their own fonts. Is there another way?

The past two days Firefox has not been displaying PDFs properly, turning 2 out of 14 pages sideways. I restarted my computer but no change. The PDFs display beautifully in Edge.

I get bills in PDF form from my water and gas provider. When I pay the bills I use Adobe to add a "PAID" sticker and a comment indicating when the bill was paid, and then I save the PDF (from Adobe) with the newly added comment. Previously I was able to open these PDFs in Firefox and the contents of the comment (added via Adobe) was visible; however, recently when I used Adobe to add a comment to a PDF and then opened it in Firefox the contents of the comment were not displayed (NOTE: I opened the PDF in Edge and it displays the contents of the comment, but it doesn't display with the same wrapping as used when the comment was created in Adobe). Interestingly, older PDFs that I added comments to still open correctly in Firefox i.e. they display the contents of the comment. I am assuming there has been some sort of update to Adobe, and was wondering if there needs to be an update to Firefox to continue to allow the contents of comments in the PDF to be displayed.

Firefox has been used to open PDFs. Suddenly, all the PDFs appear as totally black. If I hover over the tab for that PDF, it shows the little representation as normal white background. This just happened. Don't know how to correct for this.
