FOLIO should run and perform well on any modern browser compliant with recent standards from W3C (e.g. HTML, CSS, DOM) and ECMA (e.g. ECMAScript [JavaScript]). We use the current desktop version of Google Chrome from the Stable channel as a 'reference implementation' for these standards. Due to time and resource constraints, we only regularly evaluate functionality and performance against our chosen reference implementation.

Browser-specific bug reports will be accepted. Although we prioritize making things work correctly in our reference implementation, we also evaluate a bug's severity and scope when setting its priority.
