OpenDownload dialog exampleFirefox doesn’t support opening Windows executable files (i.e. files with an .exe extension); you have to save it, then manually run it. I missed the ability to execute a program directly from a browser (as Internet Explorer allows).

The OpenDownload add-on fixes that. When you click an executable, the dialog now has a “Run” button, which will cause Firefox to download the program to your system’s TEMP directory, then executes it. Sweet!


  1. I wouldn’t call it a “requirement”. It saves me 10 seconds by not having to open up Explorer, going to the folder, running it, then moving or deleting it.

    I do this almost daily.

  2. Hooray for re-opening security holes :) Since you know what you’re doing, not a problem at all.

    I quite like having my .exe files around though, be it for using it later or for knowing what the things I downloaded were. I have this download folder with subfolders too (and noticed with glee that Vista has this as default too, when I installed that on my work computer). So I wouldn’t really need this addon :)

  3. Oh, I do use another addon though (among many others of course):

    It displays a neat statusbar at the bottom of the Firefox browser window when and after you’ve downloaded stuff. A right-click allows you then to run the freshly downloaded thingy, and you have all your current downloads in a nice overview too. Clearing and removing the statusbar is just a right-click (or a click on the “downloads” button, that’s new in the current version) away.

  4. Not EVERY day, but more than the usual person probably, because the geek in me likes to try new programs; and since I’m a programmer, I usually know that I’m doing. I’ve never unintentionally downloaded something with a virus. My virus scanner has never detected one, at least.

  5. I download everything to my desktop (which is clutter-free, unlike most people it seems), where I will do something with it right-away – if it’s on my Desktop, it means I have to do something with it.

  6. I hit control+j and double click the file.

    I also have what guido has, that download bar. So I double-click the downloaded file from that bar, it cleans it out of the bar automatically and the wonderful viruses happily pour in.

  7. Hi,

    And can you expand this to automatically allow a browser page to start executables on your c: ? Standard browser security prevents this, requiring special bypasses, even though it is overkill on something that you initiate (as opposed to an external drop of an executable). If there is a simple way to accomplish this, please let me know.
