为什么我用 mac safari 搜索任何条目都要经过这么多重定向才会跳出结果，

昨天还好好的，今天就这样了，比如在safari搜索框搜索github，然后就跳转https://accounts.google.com/Logout?continue=https://www.google.com/search%3Fclient%3Dsafari%26rls%3Den%26q%3Dh%26ie%3DUTF-8%26oe%3DUTF-8%26sesinv%3D1
接下来
https://accounts.youtube.com/accounts/Logout2?ilo=1&ils=s.youtube%2Cyoutube%2Cdoritos%2Clso%2Cs.JP&ilc=0&continue=https%3A%2F%2Fwww.google.com%2Fsearch%3Fclient%3Dsafari%26rls%3Den%26q%3Dho%26ie%3DUTF-8%26oe%3DUTF-8%26sesinv%3D1&zx=-1916344746
然后
http://www.google.com/accounts/Logout2?ilo=1&ils=doritos%2Clso%2Cs.JP&ilc=1&continue=https%3A%2F%2Fwww.google.com%2Fsearch%3Fclient%3Dsafari%26rls%3Den%26q%3Dh%26ie%3DUTF-8%26oe%3DUTF-8%26sesinv%3D1&zx=-2092097261

http://www.google.co.jp/accounts/Logout2?ilo=1&ils=s.JP&ilc=2&continue=https%3A%2F%2Fwww.google.com%2Fsearch%3Fclient%3Dsafari%26rls%3Den%26q%3Dh%26ie%3DUTF-8%26oe%3DUTF-8%26sesinv%3D1&zx=1298919474
跳半天才会出现google搜索结果，这是什么原因，有遇到过这情况的嘛？
还有在搜索框输入www.google.com后会跳转到http://www.google.com/?sesinv=1
用firefox搜索google完全正常啊
