Popup action download key not triggering

[lnp5131]

It takes several attempts for the download to trigger when using the shortcut. Clicking the popup will download immediately. So far tested on google images. There seems to be a difference between clicking the popup and using the download shortcut. If the shortcut could share the same code as clicking that would be desirable.

Try disabling Use GM_download if available (under General), see if it makes a difference.

Currently using the Firefox extension, I don't see that option. Is there a development XPI?
Edit: Just checked the userscript version too, I don't see that option, but I do see it in the userscript code.
Edit2: I disabled the addon while the userscript is enabled and the option appeared. With GM_download enabled, it opens up a save dialog, which is undesirable. It then opens a tab after the dialog. With GM_download disabled, it opens a tab without attempting to save. This applies to both the click and shortcut. The speed seems to be about the same.
