After Bug #460969 landed images still lose transparency information. Tested with: Aurora 17 and Nightly 18 OS: Windows 7 x64 STR: 1. Right click on image, e.g. chrome://branding/content/about-logo.png 2. Copy image 3. Create a new file in Adobe Photoshop 4. Paste image Result: The background of the image is black. Expected: The background of the image is transparent.
Cannot reproduce on Windows 7 64 bit using the latest 32bit Nightly build. Images copied both from the example resource and web pages and pasted in GIMP 2.8.2 have an proper alpha channel. I don't possess a Photoshop license so I can't test there.
Reporter: can you check if Bug 787769 fixed this by either trying a Build of http://ftp.mozilla.org/pub/mozilla.org/firefox/tinderbox-builds/mozilla-central-win32/1347077536/ or next Nightly (2012-09-08)?
It fails with the latest Nightly when you paste the PNG into MS Paint (see my screenshot).

Paint doesn't understand alpha channels. As you can see even when opening an image for editing with an alpha channel it creates a background. An image copy-pasted from Chromium or any other program for that matter has the same issue your attachment shows. I installed and tried Paint.Net and its behavior is correct too when copy-pasting an image from Nightly.
@XtC4UaLL: It's not fixed with the latest Nightly (2012-09-10).
