Issues viewing documents when you open the application with Firefox?
If you access Online Billing Service using Firefox, you might encounter the following problem: when you try to view a document, instead of displaying the document, the application will download it.
The issue can be resolved by changing a setting in Firefox.
Step 1. Open Firefox and go to Settings.

Step 5. Go to Portable Document Format and click on the small arrow to the right of the row.
A drop-down window will open with three options:
* Open in Firefox
* Always Ask
* Save file.
Choose Open in Firefox, and the document will open in the application without being downloaded to your computer.
That's it.
