Download error on PDFs--can't find helper--please help!

Question

Hi,
I'm trying to use USPS.com to print labels. It used to work great for me until I downloaded the newest Firefox version and also installed the new CS3. I have Mac OS 10.5. When I go make a label at USPS (or try to download any PDF), I get an error like this and the document won't open, I can't print anything:
Download Error
/Users/heidinylnd/desktop/statement.pdf could not be opened, because the associated helper application does not exist. Change the association in your preferences
I have Acrobat 8 Professional. I downloaded Acrobat Reader 8 to see if that would put the required "helper" back in place. No luck. I even made that the default program to open PDFs. I used to get "Preview" to open the PDFs, but that's not working now, either. Erg!
Please help!

Answer 1

I did! I had to fix it through Firefox. Apparently something doesn't install automatically with the new CS3 or 10.5--whichever is the culprit.
Try this:
Go to Firefox in your top menu options
Scroll down to preferences
When the "Main" screen comes up, click on "Content"
Hit the last button on the page, "Manage"
You'll then be able to see what program is linked to PDFs. On mine, no action was set once I installed the new programs and deleted my old version of Acrobat.
I didn't fix this in Explorer, but I'll bet there's a similar process. I worked on finding the answer for 4 hours--finally getting help through firefox's volunteer forums! I even downloaded the new Acrobat reader and that didn't do anything before this.
Hope it works for you, too!
