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?

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.

If you want to open it confirm that you do. You will not be asked that question again after the first time you open it
Unless you are keeping Firefox in the .dmg it was downloaded in. That is to say, if you obtained Firefox in a .dmg, and you have kept the .dmg mounted, and are launching Firefox from the mounted .dmg, then you will ALWAYS get that warning. You should copy Firefox from the mounted .dmg to your Applications Folder (or anywhere you prefer), and then eject the mounted .dmg. Unless you need to install Firefox on another system, you can then delete the .dmg.

"Firefox" is an application which was downloaded from the Internet - Open?

Everytime I go to open up programs (for example, firefox) I get a dialog box like this:
“Firefox” is an application which was downloaded from the Internet. Are you sure you want to open it?
Underneath it says "AppFresh downloaded this file on May 3, 2009". These programs are installed via an administrator, but I don't want to have to click yes every time on my standard account. What can I do?

Peter:
I don't want to have to click yes every time on my standard account.
As noted in earlier posts, you should get that message the first time you launch firefox or any other downloaded application. If you get the message each time, for some reason the computer thinks it is the first time you are launching the application. Are you sure that the application is installed in the application folder? Or are you launching from the .dmg each time? If you are,
double click on the .dmg file.
When it opens drag the icon to the Applications folder and it will be permanently installed. You will need to authenticate to install, but you should not have to authenticate each time you launch the application.
Drag any icon that you have in the Dock to the Desktop
Then launch the application.
If you want to keep it on the dock click and hold on the icon
Select Keep in Dock in the pop-up menu.

How do I get downloads from the internet to open in something other then text edit?, How do I get downloads from the internet to open in something other then text edit?

Lots of times when I download files from the internet like games or something they will open up in text edit. When it comes up its just a bunch of letters and numbers, it won't actually run the application. How do I get the file to open up correctly and actually run?

Hi, do you have a link to one of these you downloaded that does this?
Basically you, in the Finder, do a Get Info on it, look for Open With & choose the proper application, but might these be Windows® only games?

"Firefox.app" is an application which was downloaded from the Internet...

This is a topic that has been posted before but I'm creating a new one because the previous discussion is closed and none of the answers solved my problem.
Each and every time I launch Firefox, I receive the following warning, - “Firefox.app” is an application which was downloaded from the Internet. Are you sure you want to open it?"
For the record, I have tried the following fixes with no success:
- Removed the Firefox folder from user/library/application support both as a user and as an admin.
- I logged in to the Mac as an admin. and launched Firefox. The message continues to pop up after doing this, while still logged in as admin.
- I logged in to the Mac as an admin, went to Terminal and listed the attributes. The "com.apple.quarantine" attribute does exist, however, when I tried removing it with (xattr -d com.apple.quarantine <FILE NAME>), I am told that the attribute DOESN'T exist. Huh?
I am trying to avoid completely removing Firefox and doing a fresh install but it may come down to this. Any help would be greatly appreciated.
Thanks!

I had a similar problem with another application. I downloaded an update to an application from the developer, and then got this message every time I ran the program. There's a script to disable this behavior entirely on MacWorld's macosxhints site.
I didn't want to disable this behavior for good, just for this one program. I realized that I had downloaded it as one user, but the first use (of the update) was as a different user. I logged in under the user ID that I used when I downloaded the application and ran the program. After that, the warning went away.
My guess is that you did something similar. Log in as the user ID you used when you first downloaded the updated FireFox and run the program. The warning should go away.
If you can't remember which user ID you used, try the brute force approach - log in as each of your user IDs and run FireFox.
Good luck!

How do I open a .fdf file downloaded from the internet?

Hello =-D
   I have been on a website many times in the past and opened pdf files. Today however, I have been trying to download an adobe file, and its showing up as a .fdf file. When I click to open (or drag and drop) I keep getting this error message:
This PDF is attempting to launch:
[insert file location here]
Are you sure you want to continue?
[Yes]
[No]
     When I click on yes, I get the same repetitive error message and nothing opens. I have tried about 30+ yes's and still nothing.
I am running windows 7 professional with Adobe XI. I know I have opened this file on this computer in the past, I do not know why it will not open now. It has been about 8 months since I have tried though...
Thanks peeps =-)

Hi Graffiti,
   Thank you for providing the website... After looking over the website you provided, I am still a bit confused. I will break it down for ya =-)
FYI, I am not that computer savvy, but I am sure you will figure that out by the end of this post...
It states:
   The easiest is when the PDF is set up to import the FDF
programmatically (using a JavaScript to import the FDF), or has the
Import FDF action. In both cases, the FDF file name is specified.
Q: How do I get Adobe to set up PDF to import FDF programmatically?
It states:
   Another possibility is if the FDF has the reference to the "base PDF"
included. In this case, opening the FDF will automatically load the
according PDF. If the base PDF is already open, the data gets
imported immediately.
Q: How do I know if the FDF has a reference to the "base PDF"?
Statement: If it should "Load automatically", I would not have an issue... or am I reading this wrong?... #confused
It states:
   You can also try to open an FDF file which does not have the
reference to the base PDF; it will then ask for the PDF to be loaded
into.
Q: How do I know if the FDF does not have a reference to the "base PDF"?
statement: Nowhere do I see it asking for the PDF to be loaded...
Thank you

How to fill in a text box on a pfd form downloaded from the internet

I am desperate to know how to fill in text boxes on a pdf form that has been downloaded from the internet

Usually you just click in it and start typing... If that's not working then maybe what you're seeing is not a real text field.
In that case you can probably use the Add Text Comment tool under the Comment panel to add text to the file.

How do I disable the feature that asks, "...is an application that was downloaded from the Internet. Are you sure you want to open it?" I get this message every time I double-click to unpack a zip file.

I am using Firefox 6.0 (I know it's an older version, but I am a doctoral student at a university that is whose system is, at this time, only compatible with this version) on an Intel Mac.

If using a mouse, you can right click on the application installer this will give you an "Open with" popup and you can chooes to open the application installer using the standard installer.
Another method to do the same exact thing is to hold the Control key while left clicking on the Application installer will give you the exact same popup menu.

I just got a new Mac Airbook with MAC OS 10.6.8 and now every time I load Firefox, it tells me it was downloaded from the internet and am I sure I want to open it. How can get rid of that message?

I know this is a standard MAC message but I never got it with Firefox before changing computers. I also downloaded Firefox 5.0 and it is still doing it.

Thanks, Jim, for taking the time, but the reply is unfortunately vague in the exact area of my confusion! "you need to copy that file to your new computer..." Well, the Import/Export instructions make it seem as if the two computers should be able to communicate this file thru wifi, but that's the linkage I can't seem tocreate with Import/Export. Should I instead email a copy to myself (thats what applecare suggested)? Copy it to and from a thumb drive? But then place the file where? And the article was helpful, but should I be trying to move the Library file or the Library.xml file (as iTunes Help suggests)? Sorry to be so clueless about it...I suppose I buy Apple in the hopes of not having to think about this stuff, which approach seems not to be serving me well. Thanks again for your time!
