This is a duplicate of bug 1379675, but that one was closed for inactivity, so I don't want to dupe this one.

Phil, thanks for reporting this. Could I get you to clarify a few details, please?
In your screenshot it looks like Nightly is running, is that right? Do you have it pinned to your taskbar?
Also, have you ever seen this happen before, and do you keep up with Nightly updates (that is, was the build you updated from a very recent one, or an older one)?

Thanks again.

Hi Matt, 

Yes, Nightly is running, but it's not pinned to my taskbar. I keep up with Nightly updates, so it was an upgrade from a very recent build, and with the last update (3rd October) it's happened again.

Also, prior to reporting this bug I have not noticed this behaviour.

Okay, great, thanks for the info.

Unfortunately that means I'm not sure what to tell you. If it were a pinned shortcut this would be an installer bug and I would know how to tell you to work around it. But as it is, there's no installer code that affects the icon used while the application is running, so I think this is out of my area.

Looks like win32-related then.

Nothing in widget impacts this.

This is happening to me as well (see bug 1495295 with more info), but this started a month ago, not a year ago.
Is there any change that was made recently that might have caused this?

The same issue here. Windows 10, 64bit.
With every update the folder with previous version is renamed to firefox.bak, then a new folder is created and the new version installed there.
Although the folder name and path is the same, the taskbar shortcut does not work after Firefox update.

The Firefox taskbar icon becomes blank and it leads nowhere,
but the Desktop shortcut (and shortcuts in any other folders that lead to firefox.exe) are working properly.

It seems to be something wrong between the update process and the system response.
