3 Hidden Features In Firefox 15 You May Want To Enable

<div style="text-align: justify;"><b>Firefox 15, which has been released a few days ago, comes with some cool features disabled by default: native PDF viewer, preferences in tab and click-to-play plugins.</b></div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">These features have been in testing for quite a while, but they are not 100% ready so they aren't enabled by default and there are no options in the Firefox preferences to enable them. But, if you don't mind an occasional glitch, you can enable them  using the <i>about:config</i> tool.</div><br /><a name='more'></a><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgdimranpR5W0DhvSfyuhue6BL-PlBjLjKVF6F9KSFCdJYvOayF4TIpLFDnvINE4vGv_eAlk1lJeLeJz0cOMQeR_mji70Wa1qjONVSRPfKBZqC4_s_byN1tJFcNOsvSNyPSmGzPllI8EmE_/s1600/firefox15-pdf.js.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="firefox 15 native pdf reader pdf.js" border="0" height="189" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgdimranpR5W0DhvSfyuhue6BL-PlBjLjKVF6F9KSFCdJYvOayF4TIpLFDnvINE4vGv_eAlk1lJeLeJz0cOMQeR_mji70Wa1qjONVSRPfKBZqC4_s_byN1tJFcNOsvSNyPSmGzPllI8EmE_/s320/firefox15-pdf.js.png" title="firefox 15 native pdf reader pdf.js" width="320" /></a></div><br /><div style="text-align: justify;">Firefox 15 comes with a <b>native PDF reader</b> that uses JavaScript (pdf.js) to open PDF files directly in the browser. This feature is disabled by default but it can be enabled by following these steps: open a new tab, type "about:config", search for "<b>pdfjs.disabled</b>" and set it to "<b>false</b>" (double click it).</div><br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj18U4e8BUXFZWIUYFUQC_jG1l0r35jHmre1SqFxiszOFFapBLFSvj-n8EE_eAo__nSnvSe2huOFLLukyPMJ_fVT5q9IDE6pdVKUpd2XNxhq8R9caD7zsCa8MkORh7bwE7ArPznxwvxOYK0/s1600/firefox15-preferences-in-tab.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="firefox 15 preferences in tabs" border="0" height="230" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj18U4e8BUXFZWIUYFUQC_jG1l0r35jHmre1SqFxiszOFFapBLFSvj-n8EE_eAo__nSnvSe2huOFLLukyPMJ_fVT5q9IDE6pdVKUpd2XNxhq8R9caD7zsCa8MkORh7bwE7ArPznxwvxOYK0/s320/firefox15-preferences-in-tab.png" title="firefox 15 preferences in tabs" width="320" /></a></div><br /><div style="text-align: justify;">In Firefox 15, you can also enable<b> 'preferences in content'</b> which makes the Preferences window open in a new tab instead of using a new window. To enable this, type "about:config" in a new tab, search for "<b>browser.preferences.InContent</b>" and set it to "<b>true</b>" (double click it).</div><br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhWCdXMVDFDdBVWMbN0FaEJVf4wc97N4ZPKzzr6IepWeullr596U7E7OYDqvY90XqOiwPweSpdXnVN1bKHBmYtcgwqogAK6pcal42mRa6SiRNbEMX_Gj4ax9mUWQpUKJnVksKHEP2ip2Qp2/s1600/firefox15-click-to-play.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="firefox 15 click to play plugins" border="0" height="250" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhWCdXMVDFDdBVWMbN0FaEJVf4wc97N4ZPKzzr6IepWeullr596U7E7OYDqvY90XqOiwPweSpdXnVN1bKHBmYtcgwqogAK6pcal42mRa6SiRNbEMX_Gj4ax9mUWQpUKJnVksKHEP2ip2Qp2/s320/firefox15-click-to-play.png" title="firefox 15 click to play plugins" width="320" /></a></div><br /><div style="text-align: justify;">And the third hidden feature in Firefox 15 is <b>"click-to-play" plugins</b>, which disables plugins like Adobe Flash by default but you can still play them with a single click. This prevents Flash and other plugins from loading automatically. To enable 'click-to-play plugins' in Firefox 15, type "about:config" in the address bar, search for "<b>plugins.click_to_play</b>" and set it to "<b>true</b>".</div><br /><div style="text-align: justify;">Note: after changing the native PDF reader and click-to-play plugins preferences in about:config, you need to restart Firefox for the changes to take effect.<br /></div><br /><div style="text-align: right;"><i>via <a href="http://www.instantfundas.com/2012/08/3-great-firefox-15-features-you-should.html">instantfundas.com</a></i></div>

With MuPDF, they can be read (even on my aging hardware) quite rapidly.</blockquote><br /><div style="text-align: justify;">Since the application focuses on speed and small code size, it doesn't come with interactive features like for filling for instance. Also, the user interface only displays the PDF; to navigate through the PDF file (next page, rotate, zoom, search for text, go to a page and so on), you must use keyboard shortcuts as explained <a href="http://www.mupdf.com/manual">HERE</a>.</div><br /><br /><div style="text-align: justify;">MuPDF also comes with a few tools (in the "mupdf-tools" package) that allow you to convert a PDF file to a series of images (pdfdraw), repair, decrypt, and decompress PDF files (pdfclean) as well as some debugging tools that lets you extract fonts from PDF files, display information about internal objects, etc. (pdfshow, pdfextract and pdfinfo).</div><br /><br /><h2>Install MuPDF in Ubuntu</h2><br /><div style="text-align: justify;">MuPDF is available in the official Ubuntu repositories, but that's an old version - 0.9 for Ubuntu 12.04. Many improvements have been added to MuPDF 1.0 and 1.1: better memory management, multi-threaded operation, better PDF rendering and <a href="http://www.mupdf.com/news">more</a>. If you wish to install the version from the official repositories, simply search for MuPDF in Ubuntu Software Center.</div><br /><div style="text-align: justify;">To install the latest MuPDF 1.1 in Ubuntu 12.10, 12.04 or 11.10, use the following commands:</div><pre class="linux-code"><code>sudo add-apt-repository ppa:guilhem-fr/mupdf<br />sudo apt-get update<br />sudo apt-get install mupdf</code></pre><br /><div style="text-align: justify;"><b>MuPDF isn't available just for Linux, the application is also available for Windows, Android and iOS:</b></div><ul><li><a href="http://code.google.com/p/mupdf/downloads/list">download MuPDF source / Windows / Android</a></li><li><a href="http://itunes.apple.com/us/app/mupdf/id482941798">download MuPDF for iOS</a></li></ul><br /><div style="text-align: right;"><i>thanks to David Reimer for the tip!</i></div>
