Sometimes your browser is set to open all PDF files when you click on a PDF. If this is the case, you will not be able to fill out fillable PDFs in the browser version. You will need to ensure that your PDF files open in Adobe so you can fill out forms and digitally sign your PDF documents.


To disable Microsoft Edge as the default PDF reader on Windows 10, use these steps:

  1. Open Settings (right click on Start button and choose Settings).

  2. Click on Apps.
  3. Click on Default apps.

  4. Click the Choose default app by file type option.

  5. Scroll down to .pdf to see the current default app for the .pdf file format and then select the app you want to make the new default. If you have Acrobat, you can choose Acrobat, if you only have Acrobat Reader DC, choose that one.


Once you complete the steps, PDF documents will open in Adobe Reader or Adobe Acrobat, instead of Microsoft Edge.
