Image duplication in Firefox on paste

[georgel-pop-lr]

Do you want to request a feature or report a bug? Bug

What is the current behavior? On the latest version of Firefox if you copy and paste an image from the viewer you get a duplicated image. Tested on other browsers and works fine.

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem.

1. Open any image in photo viewer
2. Copy the image
3. Paste the image to the editor
4. You will get two images

What is the expected behaviour? One image is being added to the editor if copy and paste.

Which versions of alloy-editor, and which browser / OS are affected by this issue? Did this work in previous versions? Affects Firefox only, previous versions don't seem to work, upgrading CKEditor 4.13.1 o superior seems to be solving this issue.

Hi @georgel-pop-lr ,

Thanks for reporting.

Just to clarify a few things, you say this is happening with the latest version of Firefox, which for me on Linux is "74.0 (64-bit)" but I just wanted you to confirm.

The second thing that I wanted to know is in which environment this is happening in, I tried to reproduce it on https://alloyeditor.com but couldn't.

Hi @julien , Just tested on Windows Firefox is "74.0 (64-bit)" on https://alloyeditor.com and was able to reproduce it. @antonio-ortega has Mac and it could reproduce it as well.
