If I install the update to Adobe Reader 10, will that cause problems with Acrobat Pro 9?

Firefox (version 15.0.1) is telling me I need to install an update to Adobe Acrobat 9.4 in order to view pdf files in my browser. I use Acrobat Pro 9. The update is actually Adobe Reader 10, and I am wondering if I install this, will it cause problems with my version of Acrobat Pro?

Because I am not sure if this is so, I have temporarily disabled the plug-in and now pdf files download automatically rather than display in my browser. I would prefer they open in my browser but do not want to upgrade to Acrobat X.

My OS is Windows Vista. I did not include the "troubleshooting information" file because I'm not sure what specific info is being requested.

Thanks for any help.

yes...you need PDF Viewer extension or a PDF reader plugin like Adobe Reader, see : View PDF files in Firefox without downloading them

i don't think installing Adobe Reader 10 plug-in to cause problems to your Pro version but i think if you install the Reader you must disable the Pro version.


thanks again

Hi ideato,

Thanks. I had done that before I posted my question.

So now the only way I can open a pdf in Acrobat Pro 9 without installing the update (Reader 10) Firefox is asking me to do is to change how Firefox handles a pdf file. So I did that, and now if I click on a pdf, it will no longer open in the browser, but it does download. I just prefer it to open in the browser.

Any other ideas?

I just checked my application options in Firefox and the only "content type" for a pdf is listed as "Adobe Acrobat 7 Document". That is curious to me. Why doesn't it just give the extension "pdf" or say "Adobe Acrobat Document" or even "Adobe Reader Document"? I had set it to open in Adobe Acrobat Pro 9.4 as the default but I prefer to open it in the browser rather than download if I can.

It's only in the last couple of days that Firefox began giving me this trouble.

If before couple of days you have no problem, check it in safe mode, select "Start in Safe Mode" and check it.

I also asked in the Adobe forums and just got a reply that it wouldn't cause a problem with Acrobat Pro 9 to upgrade to Reader 10. So problem solved, and thanks for your help!

you are welcome

The answer I got from Adobe was that I would not have a problem with functionality in Acrobat Pro 9 if I updated to Reader 10 as Firefox was requiring me to do. They were wrong! Now most of my pdf files (including ones I have downloaded and ones I have created) show the Acrobat icon instead of a thumbnail preview.

Then instead of loading quickly, like they used to do when I wanted to view a pdf in Firefox, they are taking forever. So I uninstalled Reader 10 but the behaviour didn't change. I reinstalled an earlier version of Reader (version 9.x) and I am still having the icon problem, but Firefox insists I have to update to Reader 10 to view OR download pdf files. If I do, the files take forever to load.

What to do??

update to Reader 10 then go to C:\Program Files\Mozilla Firefox\plugins and see if there is the nppdf32.dll (the adobe reader plugin) if there is find and delete the Acrobat Pro plugin.

If there is only the Acrobat Pro plugin then delete it and then go to C:\Program Files\Adobe\

open the Reader 10.1 folder then

open Reader folder then

open Air folder then

copy the nppdf32.dll and paste it in C:\Program Files\Mozilla Firefox\plugins

exit firefox and restart it.

thanks again

Thanks, I'll try this and let you know.

You can set the plugin.expose_full_path pref to true on the about:config page to see the full path of plugins on the about:plugins page.

It is best not to leave that pref set to true as it exposes that full path to web servers via the navigator.plugins object, so reset that pref to false after you are done with the about:plugins page.
