Support for extensions using XUL/XPCOM or the Add-on SDK was removed in Firefox 57, released November 2017. As there is no supported version of Firefox enabling these technologies, this page will be removed by December 2020. Add-ons using the techniques described in this document are considered a legacy technology in Firefox.
Download In Progress
My MVC application has a simple file download controller action that downloads a file.
Here is the code:
I can download/save files successfully but can't seem to get Firefox to show the file download progress. All other browsers shows the file download progress.
Does anyone know how to get Mozilla Firefox to show the file download progress?

You need to add Content-Length to the header so the browser can calculate that.
You need to send a Content-Length header that tells the size of the file in bytes, otherwise the browser has no idea how large the file is and it cannot display a progress bar.
If you pass a content-length, then it can display a progress bar as it downloads.

the latest XUL version for older versions of Firefox, SeaMonkey and PaleMoon is here:

Original Download Statusbar add-on for Mozilla Firefox is abandoned October 28, 2011:
https://addons.mozilla.org/firefox/addon/download-statusbar/
Does it mean its death? Of course not! It has been reborn! I brought it back to life!
Now it is called Download Manager (S3) and works with all Firefox versions 26+
Completely rewritten code to be compatible with the latest versions of firefox, but visual interface unchanged for use as a familiar old Download Statusbar
What is Download Manager (S3)?
Despite its compact size, Download Manager (S3) packs in more useful features than the standard download window. The fully customizable interface auto-hides when not in use, allowing full control without interruption.
HotKey:
- Ctrl + J = Open Download History page
- Ctrl + Shift + Z = Show/Hide Download Bar
- Ctrl + Shift + Backspace = clear the last downloaded item
- Ctrl + Shift + Insert = Undo last clear
- Ctrl + Shift + Enter = open the last downloaded item
- Alt + Shift + Enter = show the last downloaded item
New Features (compared with the original Download Statusbar):
- Replace Downloads Library page.
Now you have full control of your downloads history!
