I was thinking about creating a small tutorial for Wayland users to get Firefox and Thunderbird to fully use Wayland. Among other things for KDE use how to integrate Firefox almost in KDE. Both programs run absolutely stable under KDE.
So we start simple. This is more for advanced users.
In Firefox, type about:support to see what mode Firefox is running in. Scroll down until you find Window-Protokoll. Most of them should say Xwayland.
If you have Wayland as default, we first set the environment variable with any text editor as follows:
You have the normal KDE windows in front of your eyes again. Also taken from the Arch Wiki: Firefox - ArchWiki
So since I switched Firefox and Thunbderbird to Wayland, these two programs run really stable and smooth. Even web pages load much much faster. I was amazed myself what such settings can do. I wish a lot of fun trying and testing, and a nice weekend to you all.
I don’t know, I don’t use Gnome. However, it works fine under KDE. I have read somewhere that set variables sometimes cause difficulties in Gnome etc… But there each computer is different from its configuration. I have linked to an Arch Wiki article. Normally this should work much better under Gnome, because Wayland is much more mature there than on KDE. But I have to say that I use a normal 1080p monitor.
