Martin Stransky, maintainers of the Firefox packages in Fedora and RHEL, who is engaged in porting Firefox for Wayland, published a report summarizing the latest achievements in the functioning of Firefox in Wayland-based environments. <\/p>\n

Upcoming releases of Firefox aim to address the observed issues in the Wayland builds regarding clipboard management and popup handling. These features could not be implemented immediately due to the differences in their implementation approaches in X11 and Wayland. In the first case, difficulties arose because the Wayland clipboard operates in an asynchronous mode, which required the creation of a separate layer to abstract access to the Wayland clipboard. This layer will be added in Firefox 93 and will be enabled by default in Firefox 94. <\/p>\n

As for popup dialogues, the main difficulty was that Wayland requires strict adherence to the hierarchy of popup windows, i.e., a parent window can create a child window with a popup, but a subsequent popup initiated from this window must be linked to the original child window, forming a chain. In Firefox, each window could generate multiple popups that did not form a hierarchy. The problem was that when using Wayland, closing one of the popups required reconstructing the entire chain of windows with other popups, especially because having several open popups is not uncommon, as menus, tooltips, extension dialogues, permission requests, etc., are implemented as popups. The situation was further complicated by shortcomings in Wayland and GTK, where even small changes could lead to various regressions. Nevertheless, the code for handling popups for Wayland has been debugged and is planned to be included in Firefox 94. <\/p>\n
