Viewing PDF files in Firefox on Intel Mac

Before moving to my MacBook Pro, I used Schubert-IT's PDF Plugin to view pdf files directly in my browser. That plugin is not intel-friendly, though, and Adobe doesn't let mac users utilize reader within their browser, so does anyone know of another program to view pdf files directly in a browser, without having to open preview separately?

Adobe Reader and its plug-in are PowerPC code, so the plug-in will only execute in a PowerPC application. Since Firefox is now Universal, you have to tell the system to run it under Rosetta in order for it to be able to execute PowerPC plug-ins. To do this, first quit Firefox, then find the its icon in the Finder, issue the Get Info command (or Command-I) and select the "Open using Rosetta" command. Now relaunch. It should be able to run PowerPC plug-ins (and only PowerPC plug-ins) in this mode. It will also take more RAM and run slower.

Viewing PDF files in Firefox

Not sure where to post this, so here goes...
I'm using Firefox 2.0x and Adobe Reader 8.0 on iMac Core2Duo. When I click on a link to a pdf file, the file opens nicely in the browser, but at the same time downloads a copy to my Downloads folder. I don't always want a copy of the pdf. How can I prevent the file from downloading?
In Safari, I do not get the auto download; but can view the file in a browser window.

The Firefox support forums are at http://forums.mozillazine.org/viewforum.php?f=38&sid=ff76c480f43cb2ca0f66992abc0 b96ce
A search on PDF there led to one thread at http://forums.mozillazine.org/viewtopic.php?t=531066&sid=92d8bb8b44de4e8178ce56c 069e63ad9
This would suggest that if you go to Preferences>Content>File Types and open the Manage button, you may be able to alter the action of a PDF file if it is listed there among your download file types.

How to view pdf files inside firefox?

I spent hours on this. pdf.js sucks ass. Neither foxit nor adobe reader works. I have been using firefox since 2.0.0.20. I will have to quit if I can't view the pdf files inside my browser! The worst thing that has ever happened to firefox is the pdf.js shit. It is slow as shit and useless like shit. Just let pdf files be handled by the pdf program.

hello, please refer to [[How to disable the built-in PDF viewer and use another viewer]]

There have been problems reported with the latest Adobe Reader update on Mac. 
See [[/questions/925119]]
You can disable the Adobe Reader plugin in Firefox and use the Adobe Reader program or Preview instead.

I can no longer open .pdf files in Firefox 4

Ever since I moved to the beta version of Firefox 4, I have lost the ability to view .pdf files in Firefox. I was convinced this was a problem totally with Firefox, but at around the same time I upgraded from an old G4 PPC laptop to a new Macbook Pro. Now I find I can't view .pdf files in Safari either. Is this a problem with Firefox, or a problem with the way I have configured my new computer?

I have the same problem and I agree with firebunny. This is really bad style from Mozilla. You should have thought about a problem such as viewing pdf's in the browser and compatible pdf-reader plug-ins.
My Adobe Acrobat plug-in was disabled by default when I installed FF 4 rendering viewing and downloading pdf's impossible. Now I am stuck with this browser and am considering going back to the last 3.6.16 version that I still use at my workplace without any problem.
Also I agree that this has nothing to do with the pdf readers that should be installed on the PC but with FF 4. I can prove this since I installed foxit-reader which also comes with a FF compatible plug-in. Neither here did selecting this as the default pdf application help nor does it enable downloads.

Safari & Firefox behaving badly when viewing pdf files

Since upgrading my Mac to Lion, Safari and Firefox have not displayed pdf files for viewing.
SAFARI: When I click a pdf link in Safari, a dark grey blank page appears. When I try to save the pdf file to my desktop, an error message says the file is not properly formatted.
FIREFOX: When I click a pdf link in Firefox, a white blank page appears. I can successfully save the file to my desktop, and in turn open the file using Acrobat.
CHROME: Everything works normally...no problems found when viewing pdf files.
I tried dumping the plist file for both Safari and Firefox, and resetting both browsers clearing them of cache, etc., but none of that worked.
Has anyone else seen similar behavior? Anyone have a solution?
I have posted this problem twice in Apple's Safari Forum, but have had no response in almost two months.
Thanks

In Safari you to have the Acrobat PDFviewer plugin installed, or the The PDFBrowser plugin by Schubert of Germany Installed.
If you use the PDFBrowser Plugin you need the 2.4.2 version in order to work with the version 5.1 of Safari and 2.2.3 version for Safari 5.05 and lower.
In FireFox version 3.6.X and lower you need version of the PDFBrowser Plugin version 2.2.3 which also works with Safari 5.05 and lower. And version 2.4.2 for Safari 5.1 and above and FF 4.0 and above, and Seamonkey version 2.3 and above.
THE ADOBE PDFVIEWER PLUGIN has only worked with OSX for Safari. Adobe quit supporting any other browsers on the Macintosh with the roll out of OSX years ago except for Safari. And despite repeated request by many users, its gone on deaf ears.
As a result This Schubert fellow from Germany has had to fill the void. It works on "any" browser on the Market for Mac. And works for any browser for Windows except Internet Explorer.
The only thing it doesn't do is online forms which the Acrobat Plugin will. But since it only works with Safari its Useless. I'm not going to Crank up Safari just to fill in Forms.
Oh, you use to be able to install both plugins and would work fine. Now if both are installed neither works. Its either use the one that works on one Web Browser and allows form filling.
Or use the one that works on everything, but can't do forms. Oh Schubert on his Web site explains his is forbidden from installing support for forms.

Adobe 9.1.3 and FireFox 3.5.1+ "...can not be used to view PDF files in a Web Browser"

This is the issue but I'm not sure there is a resolution:
Firefox: Version 3.5.1
Adobe: Version 9.1.3
When navigating the web, click a URL that opens a PDF inside the browser and you get an error * "The Adobe Acrobat/Reader that is
running can not be used to view PDF files in a Web Browser". Please exit Adobe Acrobat/Reader and exit your Web Browser and try again". I did read a post that doing a "repair" from the Adobe Reader application should fix this, they also reference a few registry keys to check becuase the post states it's lost the application path to Adobe version X. I don't necessarily buy that "fix" and here are my details below.
In FireFox if you navigate to Tools > Options > Applications > Adobe Acrobat Document
You're given choices:
Always ask: DOES NOT WORK, produces afore mentioned error *
Save File: Works, saves the file to a directory on your PC
Use Adobe Reader 9.1 (defau...: Works, opens your PDF's outside of your web browser
Use Adobe Acrobat (in Firefox): DOES NOT WORK, produces afore mentioned error *
Use other...:
IE seems to just work as expected.
If you open Adobe Reader > Edit > Preferences > Internet > Check "Display PDF in browser" - DOES NOT WORK, produces afore mentioned error *
This would seem to be an Adobe error rather than a FireFox web browser problems since FireFox does seem to know the correct path although I suppose you can't rule out that this is a FireFox problem since 2 out of the 4 PDF open options DON'T WORK.
Any thoughts on this issue would be greatly appreciated.
Other information:
Adobe 8.1.5 works perfectly with FF 3.5.1+ when opening PDF's in the web browser, we also had no problems with previous versions either.
MSI push via Active Directory from Adobe 8.1.5 upgrade to Licensed Distribution I signed up for, Adobe 9.1.3 which was upgraded from 9.1.0, to 9.1.2, to 9.1.3 via an MSP patch.
Operating system: Windows XP SP 2, plenty of RAM, plenty of Drive
IE version this works with the new version of Adobe 9.1.3 is version 7 (7.0.5730.13)
Our FireFox MSI's come from Front Motions website and as far as I know we've never had problems with their MSI's, also tried the new release of FF 3.5.2 from their website.
I think that about covers it. Anyone else experiencing the same problems or have a patch?

After troublshooting this for the entire day today the issue seems to be a MIME problem.
If everything is woking perfectly, in Tools > Options > Applications...
You should see 4 or more things related to Adobe like "Adobe Acrobat Forms Document", etc. If you don't see at least 4 MIME entries either your Adobe installation is hosed or your FF installation is hosed. I haven't figured out which is causing the issue.
What I did was remaster my patches from my original Adobe 9.1.0 MSI with the two updates via the command line in the directories with the source files. On the 9.1.0 original file I first remastered my MST transform with the Adobe MST utility. I then applied my patches.
msiexec /a AcroRead.msi /p AdbeRdrUpd912_all_incr.msp
msiexec /a AcroRead.msi /p AdbeRdrUpd913_all_incr.msp
I then uploaded that to my network share, unlinked my group policy, made a new group policy, added a batch file to delete adobe.com from program file and the desktop on system startup even though my MST was supposed to take care of that - it's not a perfect world is it? :-)
I then reapplied my GPO's for both FireFox 3.5.2 and Adobe 9.1.3, I checked to make sure the MIME extensions were there and they were. You might have to go into your Adobe Preferences and select that open in browser setting depending on what happens or adjust your MIME settings in FireFox's options but it should work.
That's what worked for me. It's possible a few other things I did along the way tweaked it out, in my group policy on the first run I did select to upgrade previous group policies, for the remaster and repush I didn't select any previous GPO's to upgrade.
It's hard to tell what one thing tweaked it out or what combination of things tweaked out the install. I did also reinstall Adobe 8.1.5 and FF 3.0.10 before doing all this since our machines currently have that setup, I'm not sure if that affected it either, it's just hard to tell but I don't think it did simply because I had done that several times in troubleshooting this issue.
If anyone else has more specifics that would be great!

I'm using a Mac, using OS 10.4.11 and I'm trying to save a downloaded .pdf file in Firefox 3.6.10, what's the easiest way to accomplish that?

I downloaded a file from Apple, Support and it downloaded as a .pdf file.(http://support.apple.com/manuals/#powermac - item # 38 (4th page 8th item down).
I want to cut & paste that .pdf into an AppleWorks 6.2.9 word processing document. Using the select All option, so as to highlight the material on the page - I'm not allowed this option(it doesn't do it, thus I can't copy the document and paste it. It's a 7 MB download.
http://support.apple.com/kb/HE39?viewlocale=en_US " How to Download Product Manuals (PDF files) states that:
Using a Mac with Firefox:
1) Click the manual you want to download. Firefox will ask if you want to open or save the document.
2) Choose Save and select a location to save the manual.
The option/process 1) didn't take place - It simply went directly to the window showing that the download was taking place and that window shows what is being D/L and a progress bar.
In the preference options -->General I have selected "Save files to: Desktop". I have not selected /√ "Show the Downloads window when downloading a file", however, that is exactly what happens.
Thanks for any assistance that you can provide.

As you have a Power Mac you also have a alternative option to consider which is a third-party build from http://tenfourfox.blogspot.com/2011/08/601-now-available.html

Unable to open .pdf in Firefox 3.6.8 with Adobe Reader 9.3.3 installed. Error message is "The Acrobat/Reader that is running can not be used to view PDF files in a web browser."

I am unable to open a PDF file in Firefox 3.6.8. Adobe Acrobat Reader 9.3.3 is installed. I get the error message "The Adobe Acrobat/Reader that is running can not be used to view PDF files in a web browser."

You can get that error if there is still an old Adobe Reader plugin in the plugins folder in the Firefox program folder.

The scroll function on my mousepad is disabled when viewing a pdf file in firefox version 5.0. The scroll works on the pdf, but not on the other tabs. When the pdf is closed, the scroll function returns to normal. Any ideas?!

Hey thanx for the help, it worked like a charm.
I think firefox changed the application lay out, as I used to be able to choose my PDF opener from the list at " Adobe Acrobat Forms Document' where I could choose Nitro-PDF reader, but it has now moved all the way to the bottom like you suggested to the obvious place of "Portable Document Format" section.
If someone didn't tell me , I wouldn't have scrolled all the way down to be able to find it... it really should be with all its cousins up the top...
Cheers again..

I cannot view PDF in Firefox at the first time but once I manually open the PDF file from my local computer, I can view other PDF files via Firefox webbrowser

I install Adobe Acrobat 9 in my laptop which runs on windows 7. I use Firefox 3.6.8 and have the problem with the PDF file. The problem is I cannot open the PDF file in Firefox web browser at the first time I launch firefox. It shows a warning box without any message. Only OK button is shown so I can close it. However, if I manage to open the PDF file from my local computer by just using adobe acrobat itself then the PDF can be opened in the Firefox web browser. I followed the instruction on the mozilla help but nothing works for me. The problem still exists. I wonder if anyone have the same problem like me and know how to solve this. Thank you so much

Hi there!
I cannot help you, but I think we have a common problem: We got a system here running Vista SP1 with Acrobat 9 standard on it. When we open a pdf file it works normally, but when we open another pdf file, we see the first one in that second window.
Think that missing option to watch several files within a single window-thing messed up more than meets the eye ... but as we just purchased the 15 licenses, we have to use version 9.
I didn't find any clues on this problem, but I will post any new hints I get.
