Mozilla plans to increase the number of content processes of Firefox’s multi-process architecture to four (from one) with the release of Firefox 54.
Some Firefox installations are still not eligible for Firefox’s multi-process architecture. This includes systems with accessibility tools or settings enabled. Multiple processes won’t be enabled for users with extensions either, regardless of whether those are legacy add-ons, or WebExtensions.
Mozilla ran its memory test again to determine the right number of content processes. An increase in the number of content processes for the browser always goes along with an increase in memory usage.

As you know, Calibre is a powerful tool that allows you to easily manage your e-book library. It also allows you to back up the e-books that you buy online and to transfer them to other devices when your e-book reader is out-of-order.
Sometimes the problem is that e-book formats evolve rapidly and new versions have been “recently”created. For this reason I personally suggest to update Calibre very often because new version have, obviously, the most updated plugins and consequently support new formats.
The Calibre website has a good download section where you find easy instructions to update your e-book reader on almost any OS. In my experience, usually you spend less than 6-7 minutes to update Calibre and the advantages you have worth the time you spend.
Moreover, if you have problems to read an e-book on the last version of Calibre, check the file format (in my case was .azw3), launch Calibre and go in Preferences → Behaviour. Then, be sure that the file format you are trying to open/read is correctly activated into the list you find there. Enjoy your reading!
Since its invention, the pdf format has been the most versatile standard to share documents with a fixed layout. Everyday we share, read and create a lot of pdf files but sometimes we would like to modify them to create “new” personalized version more suitable to our needs.
For example, sometimes you need to extrapolate just a page from a pdf files or you want just to create different versions of the same file with few variations for your colleagues. For all these purpose pdfmod is the right solution for you.
Pdfmod has not been developed for some years because the versions we were able to find for Linux were the 2011 ones but, for what we know and tested, it still runs on all main platforms as Linux, Windows and OSX. Pdfmod is a little bit different from other similar programs because it allows you just to modify the pdf file changing pages order, deleting pages or adding new pages from other pdf files. It also allows you to change some main metadata (title, author, keywords and subjest) of your pdf file in just few clicks and, of course, you can save the modified copy of the original pdf file.
These features could be basic for more sophisticated people but I can assure you that, if you have the need to do this kind of work different times in a week, pdfmod is the software you will use more often. Installation on Ubuntu is very simple, you just have to open a terminal and type:
sudo add-apt-repository ppa:pdfmod-team/ppa
sudo apt-get update
sudo apt-get install pdfmod
and you will find a new PDF Mod launcher into the Accessories menu.
To get complete power on your pdf files we suggest pdfedit (PDF Editor) which allows you to “break” protected pdf files and modify them. To install pdfedit, use Synaptics Package Manager or the Ubuntu Software Center.
Don’t forget, when you use pdfedit you just have to open the “target” pdf file, save it using the Flatten feature you find into the Tool menu and open again the “new” file to modify it without any restriction.
