Copy and paste is broken

[dojoca]

Bug Description

I'm using Firefox 147.0.1, N8N 2.4.5.

I've tried copying and pasting nodes within the same workflow, between workflows, etc, and it doesn't work. It says "copied to clipboard", but it never pastes.

To Reproduce

See above.

Expected behavior

Paste should work.

I am accessing my environment on my local network (it's not exposed to the internet, and doesn't use SSL).

Unfortunately firefox doesn't have the equivalent to the "brave://flags/#unsafely-treat-insecure-origin-as-secure" setting.
