Firefox version:

48

OS Version:

OS X Yosemite
10.10.5 (14F1909)

I have tried reinstalling firefox couple of times and also restarting my mac.

Same for 47. Though I believe it was fine on 46. Tested on both node v4.4.7 and v6.4.0.

I wonder if it has to do with a typo in selenium-standalone? https://github.com/vvo/selenium-standalone/issues/207

@Manningham I get the same problem (on Mac Os X El Capitan, Node 6.4.0) even though my selenium-standalone has the fix applied.

Me too, any news on this?

Firefox >46 is ignored by wct-local 2.0.9+, see also https://github.com/Polymer/wct-local/issues/40 and related issues.

Only option for now seems to be to revert to Firefox 46. Even 47 didn't work.

@robdodson et al. Just ran into this myself. Now that Polymer Summit is over, got a sec to take a look?

Firefox 47+ transitioned to the new https://github.com/mozilla/geckodriver backend, which we've had issues getting to work with WCT.
I'm going to try updating our dependency on it to the latest version and try to get 49 working with it.

Status Update: Looks like geckodriver v0.10 broke port number setting, but v0.11 works ok.

[dfreedm]

Fixed in wct-local v2.0.12

Now that firefox is working, how about Safari 10? https://github.com/Polymer/web-component-tester/issues/411
