I am in the process of developping a gps logger app for cycling using Ionic framework, and it is really important to me to emulate paths in my browser, for that I use Ripple emulator extension on chrome which is a really handy tool!
But two days ago after a chrome update I started to get timeouts on all golocation api calls, so I suspected that something was not compatible with new chrome version
What I did on my mac to make it work again :
Install and launch Google Updater Uninstaller from here : http://wireload.net/products/guu-google-update-uninstaller/
Download chrome Version 35.0.1916.153 from here : http://google-chrome.fr.uptodown.com/mac/old
Launch chrome again
