Research direction

Start by reproducing the crash at https://app.uniswap.org/#/pool in the reported Firefox environment. Use the stacktrace entries in static/js/main.355ff957.chunk.js and static/js/2.cdb10fed.chunk.js to trace the failure back to its source; done means the pool page loads without this TypeError.
