The last day, I was given a brand new MacBook Pro at my new job. First thing to do: open Safari … in order to download Chrome! But I don’t know why (some traces of French settings?), the default search engine for Chrome was google.fr (french language), and not google.com (english language). Impossible to change it in the list of search engines, and there was this google:baseurl setting (set to google.fr) that I couldn’t overwrite. No way until I found the solution below.
Open the following file (on Mac OS X, files is located elsewhere for Linux and Windows users):
vim ~/Library/Application\ Support/Google/Chrome/Local\ State
And look for the three following lines:
"StartupDNSPrefetchList": [ 1, "http://www.google.fr/" ]
There, change the URL by the one you want (in my case I turned google.fr in google.com).
The default language for google should be english now. At least, it worked for me 🙂
