I can open a form but I can no longer fill in the form on Mozilla. I have no problem on other browsers.

I have been able to fill in a health claims form on Mozilla previous times. The form opens as usual but I can't fill in the information blocks. I was able to fill in the blocks when I opened the form in another browser. I have the most recent version of Adobe Reader installed.

hello STL1983, firefox 19 & above have introduced its own integrated pdf viewer - if you want to switch back to the plugin you've used before to view pdfs just go to firefox > options > applications & scroll down and define the default action for the portable document format (pdf).

View PDF files using Firefox’s built-in viewer

You may not be able to use the Adobe Reader plugin in Firefox as long as the plugin.disable_full_page_plugin_for_types pref contains application/pdf.

You can set the pdfjs.disabled pref to true on the about:config page to disable the build-in PDF viewer.

You can check the value of the plugin.disable_full_page_plugin_for_types pref on the about:config page and remove the application/pdf part if present or reset the pref to the default via the right-click context menu.
