Yes but no.<p><pre><code>    - jquery.com becomes a central point of failure and attack;
    - jquery gets to be the biggest tracker of all time;
    - cache does not stay forever. Actually, with pages taking 3Mo everytime they load, after 100 click (not much), I invalidated 300 Mo of cache. If firefox allow 2go of cache (it&#x27;s lot for only one app), then an the end of the day, all my cache has been busted.</code></pre>
