Browser extension reports app not installed

The browser extension is installed into Firefox, but the extension reports that I do not have the app installed when in fact I do.

What version of Firefox is installed?
if you have the latest version, have you installed winpcap ?

The video box will be displayed after that.
After installation, you must enable the extension in Firefox.

The problem happens on Firefox 57 when upgrading to another build. I was able to correct the problem once I completely uninstalled Firefox and Ant Download Manager, then reinstalled. The problem also holds true for Firefox 58, whenever it updates. I suspect you have an issue whenever Firefox goes through the update process. You can confirm this by downloading an older version of Firefox and trigger the upgrade to the newest version.

YES, I have winpcap installed.

I do not use Firefox. I will examine your problem.

Today the latest version of Firefox is version 56.
The other versions you mention are beta or development versions.
(these versions of firefox are not finished)

We have just updated Firefox to version 56.
The extension is always installed and functional.
- the video box is displayed correctly, and after a click on a link, the "Add a download" window appears normally and automatically, the context menu and the AntDM icon are always visible and operational in Firefox.

Since the version 56, it is not possible to update via Firefox directly up to the version 57 or 58 with the default settings.

Can you describe step by step how to reproduce the problem?
I need in more details.
1. what is version AntDM?
2. What is version Firefox?
Plobably there is a confusion with version AntFF extension and version of Firefox

How did you install the extension?
(may be extension install from there?  https://addons.mozilla.org/en-US/firefox/addon/antffw/)

With the Firefox installation file in version 57 "Quantum", I upgraded version 56. I clicked the "Update" button in the installation file.

After I made a new installation of Firefox with version 58, when this version was started, version 58 recovered the extensions and bookmarks of the installation of version 56 or 57.

The AntDM extension is always installed and activated. After checking, it works correctly.

We can not reproduce your problem.
I suggest you completely uninstall Firefox and delete its user folder. And to perform a new installation of Firefox.
