In the night assemblies Firefox, on the basis of which Firefox 104 will be formed on August 23, in the built-in interface for viewing documents in pdf added editing mode, which proposes such opportunities as drawing arbitrary labels and attaching comments. To include a new mode on the ABOUT: Config page, PDFJS.annotationedIde parameter is offered. Until now, the features of editing, built in Firefox have limited the support of interactive XFA forms usually used in electronic forms.
After activating the editing mode, two buttons will appear in the toolbar – for attaching text and graphic (drawings by hand by hand) marks. Color, lines thickness and font size are tuned through the menu buttons. When clicking with the right button, the context menu is displayed, which allows you to select, copy, insert and cut the elements, as well as cancel the changes made (undo/redo).
