I am unable to type in a text box on a PDF fillable form.


I have previously had no problem typing in text boxes on PDF fillable forms in Firefox but now nothing appears when I try in to type the information in. I am not having this problem with the same PDF forms on either the Internet Explorer or Google Chrome browsers.

Additional System Details

This happened

Every time Firefox opened

This started when...

I noticed it for the first time today which is the first time in about a week that I have tried to use a fillable PDF form.

Your system details list show shat you have two Adobe Reader plugins installed.

  1. Adobe PDF Plug-In For Firefox and Netscape 10.1.1
  2. Adobe PDF Plug-In For Firefox and Netscape "9.4.5"

Uninstall them both and install the latest Adobe Reader version.
