A number of the javascript libraries distributed with WordPress are also 
hosted on Google’s <a href="http://code.google.com/apis/ajaxlibs/" rel="nofollow ugc">AJAX Libraries API</a>. 
This plugin allows your WordPress site to use the content distribution 
network side of Google’s AJAX Library API, rather than serving these files from your WordPress install directly.
This provides numerous potential performance benefits:
<ul>
<li>increases the chance that a user already has these files cached</li>
<li>takes load off your server</li>
<li>uses compressed versions of the libraries (where available)</li>
<li>Google’s servers are set up to negotiate HTTP compression with the requesting browser</li>
</ul>

<h3>Incompatible Plugins</h3>
<h4>Better WordPress Minify</h4>
Better WordPress Minify version 1.2.2 does not yet support 
protocol-relative URLs, but <a href="https://wordpress.org/support/topic/conflict-with-use-google-libraries-152" rel="ugc">the next release is supposed to correct 
this</a>.
<h4>Gravity Forms</h4>
I’ve had reports of Gravity Forms breaking UGL, but I don’t have 
access to Gravity Forms, so I’m not sure what’s going on. If you need 
Gravity Forms you might need to disable UGL, or it might be fine, I’m 
not really sure.
<h4>WP-Minify</h4>
WP-Minify doesn’t yet support protocol-relative URLs. Add 
‘//ajax.googleapis.com/’ as a JS and CSS exclusion.
<h3>Incompatible Themes</h3>
<h4>K2</h4>
I’ve had scattered reports that UGL is stepping out of the way when 
using K2.
<h3>A Request</h3>
If you’re going to flag the plugin as “broken” in the WordPress Plugin 
Directory, please try and <a href="https://wordpress.org/tags/use-google-libraries?forum_id=10" rel="ugc">let me know what is 
broken</a>. 
I’m not a mind reader.
<h3>Technical Details</h3>
Use Google Libraries uses the following hooks (each with a priority of 1000).
<h4>wp_default_scripts</h4>
Use Google Libraries compares it’s list of supported scripts to those 
registered, and replaces the standard registrations <code>src</code> with ones that 
point to Google’s servers. Other attributes (like dependencies) are left 
intact.
<h4>script_loader_src</h4>
Use Google Libraries removes the <code>ver=x.y.z</code> query string from the URL 
used to load the requested library if it is going to load the library from 
 ajax.googleapis.com. Otherwise the URL is left unaltered. This both 
improves the chances of the given URL already being cached, and prevents 
script.aculo.us from including scripts multiple times.
If jQuery is enqued Use Google Libraries will inject a bit of 
javascript before the next enqueued script enabling jQuery’s <a href="http://docs.jquery.com/Core/jQuery.noConflict" rel="nofollow ugc">noConflict mode</a> as it would 
with the standard WordPress version.
<h3>References</h3>
Parts of this plugin (specificly, the dropping of the micro number, 
which has since been removed for better caching performance) were 
inspired by John Blackbourn’s 
<a href="http://lud.icro.us/wordpress-plugin-google-ajax-libraries/" rel="nofollow ugc">Google AJAX Libraries</a>, 
which has very similar goals to this plugin.
<h3>Future Plans</h3>
<ul>
<li>add ability to disable protocol relative URLs</li>
<li>add ability to disable on frontend and/or admin</li>
</ul>

Use Google Libraries

you will be received 5/5 stars, once it's updated and functioning as used to be. thanks...

edit: thanks for updating :) 

please update it

Allows your site to use common javascript libraries from Google's AJAX Libraries CDN, rather than from WordPress's own copies.

The need for Speed. Cache & Performance plugin for WordPress! 
You created it, we keep it fast! Did you know that…… 
You Have Just 3 Seconds To Impress Your Visitor. Don’t Lose It By Slow Loading. 95% of customer’s don´t wait if a website takes longer than 5-6 seconds to load! 
Yes, that´s a big number. 
People spend a lot of time and money on building websites and even more on marketing to get traffic… but what happens when those people come to your website and the website is slow to load? You lose sales. 
Slow loading websites lose visitors and sales. 
But we have a solution! Say goodbye to slow loading websites and say hello to Swift Performance Lite or Pro!
Get a complete <a href="https://swiftperformance.io/" rel="nofollow ugc">Cache & Performance</a> plugin for free or as a pro. 
Swift Performance will increase the loading speed of any WordPress website and provides an intelligent, modern caching system. You can even cache AJAX request, dynamic pages, and you can add exceptions (URL, page or content based rules).
Here are some of our most popular functions.
Caching. Page caching is working out of the box. It is compatible with WooCommerce, bbPress, Cloudflare and Varnish as well. It will boost your performance, improve SEO scores, and create a better user experience.
CSS and Javascript optimization. One of the most important thing for performance is optimize the delivery of static resources. Swift Performance not only combines and minifies the CSS files, but generates the Critical CSS for each page automatically. Also Javascripts (even inline scripts) can be combined, minified, and move to footer without any conflict. 
Huge combined javascript files may still be render blocking, however with our unique Async Execute solution, you can not only combine/minify the scripts, but you can run them individually as soon as a chunk has been downloaded – which provides incredibly fast JS execution, improves SEO scores and user experience.
Database Optimization. Keeping your database clean is extremely important for speed. Swift Performance has a built in DB Optimizer to clean expired transients, orphans, duplicated metadata, and spammy comments. You can also schedule every tasks. It has never been easier to keep your WordPress database clean.
Plugin Organizer. Plugins are a big part of WordPress, however sometimes not properly written plugins can cause performance issues. With Plugin Organizer you can disable plugins on certain pages, and let plugins run only where it is really necessary. You can set URL match, Frontend, Admin Pages, AJAX action rules and exceptions to get the best results.
Why you should install Swift Performance Lite? 
After reading this exhaustive features, you can probably imagine why Swift Performance is the best Cache & Performance solution for WordPress. 
It is both easy and powerful. Optimizing WordPress performance is not rocket science anymore. Our unique Setup Wizard will help you to configure the basic settings and improve WordPress performance.
We hear your voice! We are continuously improving the plugin, based on customer’s feedback & needs. This is one of the most important factors & mission. 
Give Swift Performance a try. 
Want to unlock more features? <a href="https://swiftperformance.io/" rel="nofollow ugc">Upgrade to our Pro version.</a>
Why should you upgrade to Pro? 
We added our secret ingredients to make a product for our professional users, the result is Swift Performance Pro.
Compute API. Compute API will speed up merging process and decrease CPU usage. Compute API also provides advanced JS minify, which should be used if default JS minification cause issues on your site. Compute API also provides Critical Font option, with that you can reduce font icon files’ size. This feature is essential for shared hosting users, as CPU usage is usually limited for shared hosting plans.
Critical Icon Fonts. With Critical Fonts feature you can select icons that you are actually using on your site, and generate customized icon font set from them. There is also a feature to search used icons in your theme/plugins, posts, options, etc. Once you selected the icons that you need, you can enqueue them with one click. If critical icon fonts are enqueued, the plugin will block the original version of the font CSS/font files.
Unlimited Image Optimizer. With Image Optimizer you can optimize every images on your site. It will scan the whole site, and pick up every image from themes, plugins and upload folder. Regarding that Image Optimizer is unlimited (no additional fees), you can save a considerable amount of money. You can select images individually, and run batch optimization. Default image quality can be specified in plugin settings, however you can overwrite it before starting the optimization on selected images.
Schedule DB Optimizer. Both Pro and Lite versions comes with Database Optimizer. However in Pro you can set scheduled optimization, so you won’t need to do it manually.
Whitelabel. With whitelabel option you can re-brand Swift Performance. You can change the plugin name, description, author, even the database prefix for the plugin.
Remote Cron. Pro version provides a Remote Cron option. If you set the remote cron, our API server will call wp-cron.php and run WP cronjobs as real cronjobs.
Extended WooCommerce Features. With Pro version you can’t just cache, but totally disable cart fragments AJAX calls. Pro also provide session cache, with that you can cache and preload dynamic pages like cart and checkout page for WooCommerce.
Continuous Plugin Updates. While Swift Performance Lite is maintained as well, these updates are only compatibility updates, however Pro version comes with regular updates which contains new features. Also Pro version has a Beta tester option, if you enable it, you will get updates more frequently.

Strange redirects 
If you have strange URLs in your analytics or you can see that the site redirects to an URL like this: 
https://www.yoursite.com/wp-content/cache/yoursite.com/desktop/unauthenticated/index.html 
This is caused by an improper order of htaccess rules. Probably you are using a force SSL or force www/non-www rule in htaccess. Please remove these rules from .htaccess, and insert them in Settings > General > Tweaks > Custom htaccess.
My website broke 
It is possible that one or multiple files generate conflicts when those are merged and/or minified. If you notice that you website doesn´t show correctly, you might disable merge scripts and styles.
High CPU Usage 
While Swift is generating the cache, the CPU usage can be higher than usual. Swift is using more aggressive optimization than any other plugin on the market and it needs some CPU. Usually it isn’t an issue and CPU usage can be increased temporarily, but if it goes back to normal after prebuild finished, you don’t need to worry about it. 
However, for large sites on relatively small server it can cause too high CPU usage temporarily. Actually, when the server is using CPU it is always using 100%. High usage means the CPU was used for a longer period. 
If CPU usage is constantly higher you may need check the configuration. It is recommended to:
<ul>
<li>Enable Compute API: Settings > General > Compute API</li>
<li>Enable Optimize Prebuild Only: Settings > Optimization > General > Optimize Prebuild Only</li>
<li>If you are not satisfied with Optimize Prebuild Only option, enable Optimize in background instead: Settings > Optimization > General > Optimize in Background.</li>
<li>Setting a low number of threads as maximum: Settings > Optimization > General > Maximum threads: set this to 2 or 1. 1 will make the pre-build a bit slow, so try 2 first.</li>
<li>Exclude third party CSS: Settings > Optimization > Styles> Exclude 3rd Party CSS.</li>
<li>Disable Generate Critical CSS as generating Critical CSS is the most CPU intensive process: Settings > Optimization > Styles> Generate Critical CSS.</li>
<li>Exclude third party JS: Settings > Optimization > Scripts > Exclude 3rd Party Scripts.</li>
<li>Set Cache Expiry Mode to Action based, if you are not using nonce or anything that can expire on frontend: Settings > Caching > General > Cache Expiry Mode: Action based.</li>
<li>Enable Prebuild Cache Automatically: Settings > Caching > Warmup > Prebuild Cache Automatically.</li>
<li>Setup lower Limit prebuild speed (recommended to use on limited shared hosting): Settings > Caching > Warmup > Prebuild Speed: Moderate (or Slow).</li>
<li>Exclude post types that you wouldn’t like to cache. Autoconfig should find most and exclude them automatically but you can can add them manually: Settings > Caching > Exceptions> Exclude Post Types.</li>
</ul>
