We have some end-users that might have an outdated plugin on their machine. When browising our website, the will receive a banner that says:

Firefox has prevented the outdated plugin "Adobe Flash" from running on ourSite.

We are not attempting to load the Adobe Flash plugin on ourSite, and we do not have any control over the end user's machine, their FireFox settings, or which plugins they have installed. We can't have this message pop-up on ourSite, it will cause confusion and generate support calls.

The only thing that I can think of that may be related is that we are calling navigator.plugins.refresh(false)

Is this banner being displayed as a result of Firefox refreshing it's plugin info?

Thanks, Ryan

hello ryan, would it be possible to provide a link to the page where the issue is occurring?

Hi philipp,

Unfortunately it is not a public website, it is a product that my company offers. I'm working on getting more information about the Firefox version and plugins that are installed on the machines where this occurs.

Thanks, Ryan

Are there any ads present on the page that might be causing this?

Is there any script running that checks the plugins?

Firefox shouldn't display this notification if there aren't any plugins (Flash) used.

Note that Firefox has prefs to suppress the info bar, but that won't help.

There are no ads present, it is a secure b2b app.

There is script running that calls navigator.plugins.refresh.

There is script running that embeds an <object> tag into the DOM, which loads our own NPAPI plugin via it's mimetype.
