    ESR versions are yearly if you care so much about fast releases.

    Feel free to use the LTR and only upgrade once a year if you like. Nobody's forcing you to upgrade with every release.

    It already happened. Check your settings to see if it's turned on.

    The PDF viewer in Firefox, PDF.js is an amazing piece of software. It is written entirely in JavaScript and runs in the same sandbox in which a webpage runs. So it is very safe. The layout accuracy and speed of PDF.js are simply amazing. Text selection happens just like it does in the browser. Some PDF viewers only allow you to draw a rectangle on which to do OCR. PDF.js simply lets you select the glyphs.

    This viewer has been available as an add-on for a while already.

      They did that because an awful lot of PCs hacked by a website were hacked through security flaws in the PDF viewer. Writing the PDF viewer in Javascript means that the Mozilla developers only need to make Javascript in Firefox secure to protect the machine from intentionally badly formed PDFs, and of course they already needed to secure Javascript so that's no extra security work.

      As a scripting language, Javascript is still slow compared to something like well-written C++. But Firefox 18 is pretty close to the latest version of Chrome for Javascript performance (e.g. arewefastyet.com ), so I bet the PDF viewer in Javascript works quickly enough.

    there sure is, although it wasn't on by default for me: enable pdfjs inside about:config and set the pdf in content to 'preview in firefox'
