I have a MacBook with OS 10.10.4, Preview 8.0, and Firefox 40.0.3. At Google Maps, when I try to take a screen shot with Preview (File>Take A Screen Shot>From Selection ...) I get a popup "Screen shot can't be saved. Unable to capture desktop image." This is a new issue; I have taken map screenshots with Preview and Firefox many times, but not now. The problem is not the OS or Preview because the process works fine in Chrome.

It's not Firefox! Wandering around my laptop this morning, I finally stumbled on the answer: It's Trusteer Rapport, an IBM program that protects against malware, and that my bank urged me to install.

I went to my Mac's System Preferences>Trusteer Endpoint Protection, clicked on "Stop Rapport", then went back to Firefox>maps.google.com, and, when prompted, Preview took a Screen Shot just as it always has! Who knew?

Thank you all for your suggestions.

Are you using the web site software, or Firefox? What program?

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac Options) key, and then starting Firefox. Is the problem still there?

Note that Firefox has a setting in the web developer toolbox settings to add a button to the toolbar of the Web Developer toolbox to take a full page screenshot.

The (default) file name is "Screen Shot yyyy-mm-dd at HH.MM.SS.png" and the file is saved to the Downloads folder.

You can right-click and select "Inspect Element" to open the Inspector (Firefox/Tools > Web Developer) and have access to the developer tools including the gear icon to access the toolbox settings and the "Take a fullpage screenshot" (camera) button once you have enabled this button.

If you need more options like a delay or saving the image to the clipboard then you can use the Developer toolbar and invoke the screenshot command.

  • A quick way to save a screenshot is to press the "s" and press the Tab key to accept the screenshot autocomplete suggestion.
  • For help about this command, use: help screenshot
