How to disable firefox asking if I really want to launch .msi file?

Every time I download *.msi file and try to launch it through firefox last downloads menu (or library window) firefox warns me that this is executable file and asks do I really want to launch this. This is really annoying.

How to disable this warning?

P.S. I do not want to use about:preferences#privacy to disable warning me about insecure downloads! I want to only remove this stupid warning before launching legitimate .msi files just because they are .msi files. I still want firefox to scan all downloads.

OK, I've found it in the source code.

Add the following pref: browser.download.skipConfirmLaunchExecutable = true

Go to about:config and set browser.download.manager.alertOnEXEOpen = false.

Unfortunately it did not help. I had it on disabled earlier. I have no warning on exe files, only on msi files. This is something new, silently added in firefox 65.

I created string and set it to true and it did not work. Now I cannot create boolean because it only changes what string says.

  1. Right-click on the pref and select Resetuj.
  2. Restart the browser.
  3. Try again to create a boolean preference.

Thanks! That solved the problem, string disappeared after resetting it. Now I created boolean and message is not popping up on msi files!
