[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?

I wanted to reach out and mention that I am also running into this issue with my new deployment. Also running the debian-kde branch, though I haven't tested it with any other versions.

I only have the problem running any Firefox based browsers (so far have tried firefox, firefox-esr, firefox nightly, zen browser), but in my case it only seems to happen upon my first time clicking in, once I click again the issue subsides until I move to a different window/tab on my host machine and come back to webtop.

This is not an issue, this is how Firefox chose to implement the seamless clipboard api.

Firefox is a mess, they are years behind on w3c initiatives and has a lower browser share than Opera. I want it to exist but it seems the people taking the Google money are killing it intentionally.

With that said you can disable this with https://retiolus.net/posts/how-to-bypass-copy-paste-restrictions-in-firefox/
