Hi Paisleyborn, what happens when you try to download or view the bill? For example, you click a link or a button and then --

• nothing happens
• blank page appears
• error message appears (what does it say?)
• something else

If you test the same link or button in Microsoft's Edge browser, what happens there?

Nothing happens when I try to download the bill in Firefox. In Microsoft or chrome there is no problem. the problem only occurs in Firefox.

Could you check your PDF setting? By default, it is "Preview in Firefox" but you also could try setting Firefox to open the PDF in your preferred external viewer (such as Adobe Reader) or to save the file automatically. This article will get you to that setting: View PDF files using Firefox’s built-in viewer. Do any of those options work for this site?

Also, in other browsers, what happens when you click the link/button? In particular, does the site:

(A) replace the current page with the PDF, or (B) open a new window/tab with the PDF, or (C) show a dialog to Open/Save the file, or (D) immediately download the PDF?

If a new window/tab opens in the other browsers, perhaps Firefox or an add-on is blocking popups too aggressively.
