We may provide alternative clipboard (async) for Wayland code to text/fix various clipboard issues we have on Wayland now.

When widget.wayland.async-clipboard.enabled use async clipboard and D&D handlers provided by Gtk.

I use this command for local testing:

MOZ_ENABLE_WAYLAND=1 ./mach mochitest dom/base/test/test_copypaste.html --setpref widget.wayland.test-workarounds.enabled=true --setpref widget.wayland.async-clipboard.enabled=true --enable-webrender

https://hg.mozilla.org/mozilla-central/rev/ca7dd68c51a2

To enable the async clipboard support, please go to about:config, set widget.wayland.async-clipboard.enabled to true and restart browser.

It works perfectly now, both with and without the option enabled.
Thank you all !

On my system (GNOME Wayland / Arch Linux) there's a visible delay (~500 ms?) between pasting and the new text being displayed, which is quite annoying when you're pasting into the address bar.

Can you open a new bug for it and attach clipboard log of that? (run with MOZ_LOG="WidgetClipboard:5" env variable).
Thanks.

I will, but I'd rather wait for bug 1727268, just in case it's caused by blocking on that mutex.

I have another question: I'm seeing relatively many clipboard-related crashes, some with different stack traces. crash-stats.mozilla.org doesn't have a bug associated with them. Should I do anything about this, maybe click "File a bug" on c-s.m.o?

Already did, bug 1726360.

Feel free to file them, I can look at it.

I've just downloaded and installed FF93 from the Fedora 34 repository. Alas, this problem is not fixed. Can we take a look at this again?

Async clipboard was implemented in 93 but it's enabled by default at 94. In 93 you need to go to about:config and set widget.wayland.async-clipboard.enabled to true and restart browser.

Confirmed. Works like a charm. Thanks for all the hard work. I appreciate it very much.

Setting widget.wayland.async-clipboard.enabled to true also seems to have fixed a problem I had (on Fedora 34) where I could copy from other applications and paste to Firefox, but not copy in FIrefox and paste to other applications. Thank you.
