Is it a question about desktop Firefox?

I want the Adobe Acrobat extension primarily for my desktop computer use which is Microsoft Office format.

Hi Steve, is the problem with reading/downloading PDFs, or converting web pages to PDF?

The settings for how you read/download PDFs are set on the Options page: View PDF files in Firefox or choose another viewer.

For creating PDFs, if you have a paid version of Acrobat -- DC or 2017, for example -- and need Adobe's extension to show up in Firefox, please see this earlier thread for a workaround: https://support.mozilla.org/questions/1290339

Do either of those suggestions help?

I use Adobe Acrobat most on my desktop which uses Microsoft Office programs.

Hi Steve, I interpret this to mean you run the Windows operating system. But do you have the free Adobe Acrobat, previously called the "Reader", or the paid version that comes with the Acrobat browser extension?

I pay for Adobe Acrobat DC so I can convert online documents (in Google as my browser) and I can edit text when documents are sent to me. Mozilla Firefox posted a message many months ago saying it would no longer support Adobe Acrobat and there is now no "button" on Firefox to use to convert an online article to Adobe.pdf format.

Hi Steve, try the manual install method in the thread I linked earlier: https://support.mozilla.org/questions/1290339
