====== Google Analytics 拖慢 Firefox ======
這一、兩年來陸續在使用 Firefox 看到部分網站讀取時一直等待 Google Analytics，不僅嚴重拖慢網頁讀取速度，甚至 Firefox 還會開始轉彩球（Mac OS X 上程式無回應）。

剛一查發現還真的有這問題 <span ex>[[http://superuser.com/questions/611370/tired-of-waiting-for-www-google-analytics-com-can-a-browser-setting-opt-me-o|Tired of waiting for www.google-analytics.com -- can a browser setting "opt me out"? - Super User]]</span>

網友推薦的 Firefox addon（連 MAO 網站自己好像也搭配 Google Analytics 啊！）：
  - [[https://addons.mozilla.org/en-US/firefox/addon/ublock-origin/?src=search|uBlock Origin :: Add-ons for Firefox]]
  - [[https://addons.mozilla.org/en-US/firefox/addon/requestpolicy/|RequestPolicy :: Add-ons for Firefox]]
  - NoScript

或是不要再額外裝 Firefox plugin，直接暴力修改 ''/private/etc/hosts'' 把 Google Analytics 擋掉呢？我先加上了<code>
0.0.0.0 www.google-analytics.com
0.0.0.0 google-analytics.com
0.0.0.0 ssl.google-analytics.com</code>

一邊觀察成效的同時，另外也搜尋一下如何對付 gstatic.com ☞ [[https://www.google.com.tw/search?q=gstatic.com+slows+down+firefox&ie=utf-8&oe=utf-8&gws_rd=cr&ei=B4JQWIjbOoHg0gTquK_ABA|gstatic.com slows down firefox - Google 搜尋]]

再繼續研究看看好了，先觀察暴力擋 Google Analytics 有無成效。
