Hi adityabhargava01-
My first suggestion is to upgrade to the most recent version of Firefox by going to this link:

My second suggestion is to read this article on how to many your preferences on how Firefox deals with PDFs and all other file types:

Is it possible to create a editable pdf with validation(required field) using Adobe Acrobat pro version?

Hi,
the subject says it all. I have downloaded the trail version to see if its possible to create a editable pdf with validation(required field) using Adobe Acrobat pro version?
Basically, I will have to create a pdf form where users fill it and send it back to me. there will be required fields (the textbox and check box) that user need to fill before saving the editable pdf?
Is it possible. if so, can someone kind enough to point to me right directions?
Thanks in advance.

Thanks for reply. What I am trying to achieve is to give an option for the user to download the pdf form and once the user tries to save the pdf, it validates with the required field. I managed to create the editable pdf with required fields option. I just need that validation to be done when user click on save file. How can I achieve this? thanks so much for your help.

Welcome to the Apple Support Communities
You can use Preview to open PDFs. Right-click a PDF file and go to Open with > Preview

Hello. My safari (and i keep it updated) cannot open PDF files. Should i install Adobe Reader and which version????? I have Mac Book Pro running OS 10.9

My safari (and i keep it updated) cannot open PDF files.Should i install Adobe Reader and which version????/ I have Mac Book Pro running OS 10.9
Please help me!!!!

Back up all data.
If Adobe Reader or Acrobat is installed, there should be a setting in its preferences such as Display PDF in Browser. I don't use those applications myself, so I can't be more precise. Deselect that setting, if it's selected. Otherwise do as follows.
Triple-click anywhere in the line of text below on this page to select it, the copy the selected text to the Clipboard by pressing the key combination command-C:
/Library/Internet Plug-ins
In the Finder, select
Go ▹ Go to Folder
from the menu bar, or press the key combination shift-command-G. Paste into the text box that opens (command-V), then press return.
From the folder that opens, move to the Trash any items that have "Adobe" or “PDF” in the name. You may be prompted for your login password. Then quit and relaunch Safari, and test.
The "Silverlight" web plugin distributed by Microsoft can also interfere with PDF display in Safari, so you may need to remove it as well, if it's present. The same goes for a plugin called "iGetter," and perhaps others — I don't have a complete list.
If you still have the issue, repeat with this line:
~/Library/Internet Plug-ins
If you don’t like the results of this procedure, restore the items from the backup you made before you started. Relaunch Safari again.

When viewing the applications tab of my firefox preferences, PDF file formats are not in the list of possible formatts, how do I add it so that I can open PDF file in my browser?

I am running OSX 10.5.8 currently, and have followed all of the tips and advice on the help sites (IE. uninstalling, installing pluggins, programs like adobe, and reinstalling firefox). I tried deleting and resetting the mimetypes.rdf file and the pluginreg.dat files. I have noticed that when you open the FF preferences window, and look at applications, there is no Portable Document Format file type listed. How do I fix this?

Install '''PDFescape''' extension from the FF add-on gallery. I think it may help to your problem

Unable to open pdf files using Internet Explorer and Adobe 9.1

We are unable to open any/all pdf files in Internet Explorer 6 or 7 using Adobe Reader 9.1 on Windows XP SP2.
The error message is that IE has a problem and sorry for the inconvenience.
Clicking "OK" closes IE.
We did not have any issue with Adobe Reader 8.1.
What we did to date:
1. Uninstall Adobe Reader 9.1
2. Run Windows Clean Utility to remove any remnant of Adobe Reader 8
3. Re-install Adobe Reader 9.1
Any other suggestions?
Need to have this upgrade.

I'm having a similar issue. Prior to upgrading to Acrobat 9.1 I was able to view PDFs from IE 6. No longer. Instead I get a message: "Error opening document. File cannot be found."
Help?

I click Yes and get to my computer where I can find the above mentoned attachment which I think I had previously saved. I then get the attachment whick I can print.

Unable to open pdf files on IE if I use Acrobat 6.0 - urgent

Hi, on clicking a hyper link, I need to read a PDF file from a server, and then
I need to show that PDF file on the IE window to the user, for that I'm using the following code -
javax.servlet.ServletOutputStream Pout = response.getOutputStream();
     response.setContentType("application/pdf");
     response.setHeader("Content-disposition", "inline; filename=" + "ClientStatement.pdf");
     java.io.FileInputStream fileInputStream = null;
     java.io.BufferedInputStream bufferedInputStream = null;
     ServletContext objServContext = getServletContext();
String strDirectoryName = objServContext.getInitParameter("ClientStatementsPath").toString();
     fileInputStream = new java.io.FileInputStream(strDirectoryName + strFilePath);
     bufferedInputStream = new java.io.BufferedInputStream(fileInputStream);
     byte[] bytes = new byte[bufferedInputStream.available()];
     response.setContentLength(bytes.length);
     bufferedInputStream.read(bytes,0,bytes.length);
     Pout.write(bytes);
     Pout.flush();
     Pout.close();
     bufferedInputStream.close();
It is working fine, if client is using Adobe Reader 5.0, if he is using Adobe Reader 6.0 then it is showing empty.
pls help to resolve this problem,
thanks in advance,
regards
Kamesh

I dunno, but setting the content length to be bytes AVAILABLE from the buffer doesn't seem correct to me. I think you can get away without setting content length.
like this:
bufferedInputStream = new java.io.BufferedInputStream(fileInputStream);
byte[] bytes = new byte[1000];
while ( (bytes = bufferedInputStream.read(bytes, 0, bytes.length)) != -1){
    Pout.write(bytes);
Pout.flush();
POut.close();
bufferedInputStream.close();Other questions:
How long does it take to generate the file? Possible timeout?
Try going to edit:preferences, and check the Internet options. Does it work if you disable "display in browser"?
Hope this helps in tracking it down.

Why does Preview not display some PDF content which is visible in Adobe Acrobat?

I have occasionally received PDFs from multiple different sources for which some content (words, checkmarks, etc) simply does not appear in Preview. The full content does appear when view with Adobe Reader. Unfortunately, when viewing in Preview, there is no indication that anything is missing.
What is going on here? Is there some solution? I prefer Preview because it is fast ans versitile, but if it doesn't actually display the whole thing...

The answer is that some pdf options are not available in Preview. Adobe has a number of annotation and graphics and even file linking options which do not carry through to Preview. In other words, Preview is not 100% compatible with Adobe Acrobat, Preview is less capable, although it can generally handle probably 99% of what people do in pdf format. But there is a small collection of things that do not come through properly with Preview.
One obvious example is forms. While this may not be the situation you are asking about, note that Adobe Acrobat can create forms that one can fill out with Acrobat Reader. These forms have cells and one can go through them and enter text or information into those cells with Adobe's software. Sometimes the forms even include boxes to be checked or highlighted and so forth, all possible with a click using Adobe's own software. However Preview often is unable to enter the data on those forms. Again, the reason is that for certain somewhat advanced options, Preview does not have every capability that Adobe Acrobat (or Acrobat reader) has.
For simple stuff, however, Preview generally works well.

Quality of pdf files not clear after conversion (Adobe Acrobat 9.0 Std)

Hi,
I am using Adobe Acrobat 9.0 standard and my computer is running on Windows XP SP3 (with Office 2003 SP3). Everything used to works fine until my laptop crashed and I need to re-install everything.
Now when I want to convert PowerPoint presentation files (with pictures, diagrams), the pdf version becomes not clear and the fonts are smudged.
I have re-install Adobe twice but ended up with the same problems. My colleague is able to convert the same PowerPoint using CutePDF without any problem.
Please help. Thanks.

You may want to try the following steps:
open a pdf file
click Edit
click Preference
in Resolution section: select Use system setting: 144 pixels/inch
in Rendering section: select For Monitor, select Smooth line art, select Smooth images, select Use local fonts, select Use page cache
in Page Content and Information section: select Use smooth zooming, select Use smooth scrolling
click OK

Create- combine multiple pdf files has stopped working? Adobe Acrobat Pro on Mac

Hi It's my first time on this forum. I'm a regular user of the create pdf by combining multiple pdfs. It always works no questions asked, but just a few days ago when I'd click on create and select Combine files into a single pdf nothing happens. Usually a pop up would let me identify the files to combine.
Any help would be appreciated.
Thanks

Hi Anne,
If all you need to do is combine the PDFs, and Acrobat continues to give you problems, you can have a go at the free program PDF Split and Merge. You will need Java installed on your computer to run it (Java apps run on all systems -- Mac, Windows and Linux, and mobile systems like Android and iOS). Acrobat hangs for me sometimes when trying to combine multiple PDFs, especially if the individual PDFs are of considerable file size. PDF "Sam" works fine for me when Acrobat won't. It also uses less memory and resources than mighty Acrobat, on my RAM-challenged (Windows) machine. As stated above, PDF Sam is a Java program, so it should work also on Mac. There are also system-specific downloads available on the author's web page.
Have a look-see at PDF Split and Merge at pdfsam.org/download (Go to "Other Platforms and Versions" to find the Mac-specific version).
Download Java (if it's not installed!) at java.com (Go to java.com/download/manual.jsp and scroll down for Mac OS X). *Java 7 requires at least Mac OS 10.7.3 to install; check "About This Mac" at Apple menu -> About This Mac... to see your system version.
Good luck
