Clipboard doesn't work in Firefox with any Sandboxie Plus 1.16.x (including Classic). I am on the latest Sandboxie Plus 1.16.8, Windows 11 Pro 25H2 OS Build 26200.7171 and latest Firefox 145.0.1. I cant copy out of sandboxed Firefox. Unsandboxed Firefox works fine. Other sandboxed browsers work fine.

The issue is intermittent. Copy doesnt work about 50% of the time. Microsoft Defender and other security settings are on default. I dont have any other security software running. I tried all 1.16 versions, including latest Classic, the issue is present in all of them. When tried to open Firefox in 1.15 versions, it would not even open.
