Platform
- OS
- Linux (Kubuntu, Ubuntu, Fedora)
- Firefox version
- Atleast 49.x and 50.x
- Extensions
- Atleast one extension installed. Extension must be the kind that requires Firefox to be restarted when enabled/disabled.
How to reproduce
- Go to http://petrit.net/dragndrop.html
- Select some text on some other application than Firefox. For example a texteditor.
- Drag the text and drop it on the yellow area on the web page.
- The page shows the content of event.dataTransfer.types in textarea. And the values of event.dataTransfer.getData(type) for types text/plain, text/html and text on other textareas.
What should happen
Types should include text/plain (and possibly text/html depending on where the text is dragged from), and the dragged text should be shown in the textarea for text/plain.
What happens
The "types"-textarea shows only the types application/x-moz-file and Files as if some files were dragged. Other textareas are empty.
Other
Restarting Firefox in safe-mode, i.e., all extensions disabled, does not help, if those are normally enabled. Only really disabling them helps.
Dragging text from inside the Firefox works always as it should.
Drop text here!
