there are so many similar questions in stackoverflow and the one you are referring is 3 years old question that would not solve the current version problems — Mithun Shreevatsa, Jul 04 '16 at 15:48

I'll still keep the answer since it is protractor specific and has some additional information about the problem. Hope it'll help others with similar protractor+firefox issues. — alecxe, Jul 04 '16 at 15:56

Firefox 47 has compatibility issues with the selenium webdriver 2.53 (you have 2.52, but I think it is still a problem). You need to either downgrade Firefox to 46.0.1 or install the latest development version of Firefox which contains the fix.

Or/and, you should upgrade Protractor to the latest (3.3.0 at the moment), which will bring the latest selenium-webdriver package with itself (note: Protractor tries to sync with the latest updates in selenium-webdriver, but 3.3.0 specifically depends on the same 2.52.0, while there is 2.53.2 out there - the next 3.4.0 will have that installed).

Firefox 47 is the latest version as of now. So do you want me to try upgrading protractor or downgrade Firefox? Chrome has no issues FYI – Mithun Shreevatsa Jul 04 '16 at 17:13
Firefox 47.0.1 already has the fix. Alex is right - latest selenium 2.53.1 should be used with latest firefox, but protractor dependency isn't updated yet. – Xotabu4 Jul 04 '16 at 17:44
