No, Firefox just flat out has some worse JavaScript performance and bugs/incompatibility with other browsers. I’ve been/am currently burned by Firefox’s pretty poor IndexedDB support and performance. IDBObjectStore.getAll() fails with a cryptic exception if you store too much in IndexedDB (iirc 256mb is the limit), whereas Chrome and Safari have no problem with it. It also has terrible performance - about 4x slower than Chrome, with Safari having the best performance.
