[BUG] Firefox 131 click into webtop causes paste-overlay

[hgw77]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

When I access the webtop desktop (tested with both Debian KDE and Debian XFCE) from the host machine, I encounter a 'paste' overlay. To dismiss this overlay, I need to click the right mouse button. This was not happening before.

Expected Behavior

When I click on the webtop desktop, I can work without being interrupted by the paste overlay.

Steps To Reproduce

used webtop versions:

• lscr.io/linuxserver/webtop:debian-kde-version-72bc50ca
• lscr.io/linuxserver/webtop:debian-xfce-version-86f50ed3

1. open webtop desktop
2. click with the mouse on the host desktop
3. click with the mouse into the webtop desktop

I am the only one with that issue? This Problem also occur when I use a second screen. When I click on the second screen I can see also the "Paste" overlay. This makes the second screen not realy usable.

I did some investigation and found that this issue is not only related to webtop and leads to common issues with the clipboard integration and Firefox.

It turns out when I disable dom.events.asyncClipboard.clipboardItem and dom.events.asyncClipboard.readText in about:config the problem disappears. But with the cost that the seamless clipboard integration between host and webtop is not working anymore (note: the seamless clipboard is only working with a valid https connection). Here is a discussion about that topic.

My question is now why there is some kind of clipboard context menu triggered when I click into the webtop desktop?
