Any idea?

Answer 1

There were issues with protractor with Firefox v53.0

(refer https://github.com/angular/protractor/issues/4253 ), are now resolved.

Protractor works well with higher versions of Firefox.

1. Upgrade Mozilla Firefox to version > 59.0 (Firefox Quantum)
2. "Use directConnect: true" in the conf.js
