"[App] is an application downloaded from the Internet. Are you sure you want to open it?" problem

more options

Most apps that I download with Firefox (Firefox is my default browser so I download basically all apps with Firefox) give me the error that "[App] is an application downloaded from the Internet. Are you sure you want to open it?" When I download the same with Safari I don't get the error so it appears like it is a Firefox issue. Is there some setting I can make to get rid of this problem? I've followed some instructions concerning this from the internet but none have worked. Some sites say that after the first time opening the message should disappear but it doesn't. I am using El Capitan and the most up to date Firefox.

This is not the problem I am talking about. It has nothing to do with unidentified developers but just a warning that I may not want to open the app because it was downloaded. In past OS’s that warning would appear occasionally (probably the first time I opened an app) but now it always appears when I open an app that was downloaded with Firefox. As far as your advice is concerned, I always have the “Anywhere” option checked in “Allow apps downloaded from”.

Does it matter where you download the file?

The closest thing I found to bypassing/cleaning this is the following article which is five years old now: http://osxdaily.com/2010/09/12/disable-application-downloaded-from-the-internet-message-in-mac-os-x/

That is the same advice that I found (from different sites). I am guessing that with El Capitan's new security features that maybe that doesn't work anymore? I don't get any errors when I run that command but it doesn't help in any way. If you can't help me I will just live with it or wait until there is more El Capitan specific instructions.

I can't possibly read every thread here, but I don't recall seeing this one before. You might try posting on Apple's forums to see whether anyone there can explain how you do or do not get a warning with the identical download based on the browser you use.
