How do I stop click-thru "'Firefox' is an application downloaded from the Internet. Are you sure you want to open it?"?

Every single time I launch Firefox 20 under Mac OS X 10.7.5 I get the click-thru warning message "'Firefox' is an application downloaded from the Internet. Are you sure you want to open it?". How do I stop this? There are internet postings and previous postings about solving this using Terminal commands for OS X 10.5.x & 10.6.x, but these commands do NOT work in 10.7.x or 10.8.x. This seems to be a Firefox ONLY issue, and solving it by globally turning off OS X security features as recommended before in a previously closed thread seems like a really BAD solution. Is there a "Firefox only" solution, or will I just have to stop using Firefox?

Make sure that Firefox gets installed properly.

Open the Firefox disk image (DMG) file and drag the Firefox program to the application folder on your hard drive. You shouldn't double-click the Firefox application to run it from the disk image, but drag it out of the DMG folder instead.

Hello,

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.

To Reset Firefox do the following:

  1. Go to Firefox > Help > Troubleshooting Information.
  2. Click the "Reset Firefox" button.
  3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
  4. Firefox will open with all factory defaults applied.

Further information can be found in the Refresh Firefox - reset add-ons and settings article.

Did this fix your problems? Please report back to us!

Thank you.

I had upgraded to Firefox 20 using the automatic update process, so the last time I'd downloaded a .dmg and manually installed Firefox was a long time ago. I trashed Firefox 20, downloaded a new .dmg and manually transferred to Applications folder and this persistent message ended. I assume if I'd ever launched from the open .dmg the same error message would result, so the fix offered was a solution even though the cause was something different since I only used the automatic update process and never manually handled Firefox .dmg downloads.
