Firefox Beta and Developer Edition
Release Notes

Dragging images across Firefox tabs and instances is now more reliable and works with web apps like Google Drive and Photos

It's now possible to import bookmarks, history and passwords not only from Edge, Chrome or Safari but also from Opera, Opera GX, and Vivaldi for all the folks who want to move over to Firefox instead!

GPU sandboxing has been enabled on Windows.

Note: A bug in the popular X-Mouse Button Control (XMBC) tool may cause mouse wheel scrolling to stop working. Affected users should update to the latest version of XMBC (2.20 or higher) which contains a fix for this issue.

On Windows, third-party modules can now be blocked from injecting themselves into Firefox, which can be helpful if they are causing crashes or other undesirable behavior.

Date, time, and datetime-local input fields can now be cleared with Cmd+Backspace and Cmd+Delete shortcut on macOS and Ctrl+Backspace and Ctrl+Delete on Windows and Linux.

Firefox now supports CSS named pages, allowing web pages to perform per-page layout and add page-breaks in a declarative manner when printing.
