Enable Flash for Chromium Browser in Ubuntu 14.10

Last updated: October 10, 2014

If you’re using a Chromium based web browser in Ubuntu, you may find that the Adobe Flash Player installed from Ubuntu Software Center does not work all the time.

Because ‘Aura’ for Linux, which replaces GTK+, lacks coded support for NPAPI plugins, the “old” Adobe plugin in Ubuntu repositories does no longer play Flash content in Chromium based web browser.

As a workaround, you can use the ‘Pepper Flash’ which is bundled with Google Chrome that provides the latest Adobe Flash Player for Linux.

Chromium with Lastest Adobe Flash

1. Click the link below to bring up Ubuntu Software Center and click the install button:

This will install the package “Pepperflashplugin-nonfree“, which will download Chrome from Google, unpack it and make the included Pepper Flash Player available for use with Chromium.

2. After that, relaunch Chromium browser and Flash should now work. If not, close the browser and run below command in terminal (Ctrl+Alt+T) to tell the plugin location:

sudo update-pepperflashplugin-nonfree --install

That’s it. Enjoy!

How to Enable Flash for Firefox in Ubuntu 14.10

Last updated: October 10, 2014

Firefox browser does not play flash out-of-the-box in Ubuntu. We need to manually install the Adobe Flash Player and below is how.

As you may know, Adobe abandoned flash for Linux in 2012. For Flash Player releases after 11.2, the Flash Player browser plugin for Linux will only be available via the “Pepper” API as part of the Google Chrome browser. Adobe will provide security updates for Flash Player 11.2 for five years.

The Adobe Flash Player 11.2.x is still available in Ubuntu repositories and below is how to install it in Ubuntu 14.10.

Click the link below to bring up Ubuntu Software Center and click the install button:

The package doesn’t contain the actual flash player, it’s only an installer that automatically downloads and installs the source tarball from the Canonical Partners repository.

If you have already enabled Canonical Partners repository, available in Software & Updates -> Other Software tab, you can directly install the Flash Player (the real package) package from Ubuntu Software Center:

Once installed, re-launch your Firefox browser and enjoy!

Useful Tools to Customize Your Ubuntu Unity Desktop

Last updated: October 12, 2014

When the beginners want to customize their Ubuntu Desktops, System Settings may be the thing that first come to mind.

System Settings is available in Unity (left) Launcher out-of-the-box, it provides a group of utilities to configure your Ubuntu desktop settings, such as backups, keyboard and mouse properties, displays, network and security settings, and more.

However, there are a few basic desktop settings that are not covered by System Settings, such as GTK / icon / cursor themes, fonts, desktop icons, system cleaning and so forth.

Below I’ll show you three simple tools that may help you customize your Ubuntu Desktop:

1. Unity Tweak Tool

Unity Tweak Tool was started since Ubuntu 13.04. It provides a clean and easy-to-use user interface to configure the default Unity desktop settings.

The open-source tool provides detailed configurations for Unity Launcher (left sidebar), dash (the search box), top panel, web apps, window effects, themes, fonts, and more.

One of the most notable features of Unity Tweak Tool is that each configuration tab contains a “Restore defaults” button allows to revert original settings.

To install Unity Tweak Tool, click the below button to bring up Ubuntu Software Center and click install:

2. Ubuntu Tweak

Ubuntu Tweak was started 6 years ago since Ubuntu 8.04. It’s one of the most popular Ubuntu configuration tools. Unfortunately, it is not made into Ubuntu universe repositories so far.

Ubuntu Tweak features:

  • a quick overview of your system information
  • quick install featured applications.
  • configure themes, fonts, login settings, quicklists (Launcher icons’ context menu), and more
  • clean browser cache, system cache, and old kernels.
  • provide online wallpaper HD.

Ubuntu Tweak .deb installer is available for download at the link below:

Ubuntu Tweak Download Page

3. Gnome Tweak Tool

Gnome Tweak Tool is a basic configuration tool specially designed for Gnome Desktop Environment. It’s a good choice if you’re using Gnome Shell session in Ubuntu. But it looks broken in the default Unity DE due to the new client-side decorations.

Gnome Tweak Tool is available in Ubuntu universe repositories, just search for and install it in Ubuntu Software Center.

QupZilla 1.8.1 Released, How to Install it in Ubuntu 14.04

QtWebKit web browser QupZilla 1.8.1 has been released recently. Here is how to install / upgrade it in Ubuntu 14.10, Ubuntu 14.04, Ubuntu 12.04 and their derivatives.

QupZilla is a free and open source browser that uses QtWebKit engine. Additional effort was put into seamless integration of the browser with the native look and feel of users’ desktops. Some additional features of the browser include the integration of history, web feeds and bookmarks in a single location, the ability to take a screenshot of the entire page, and Opera-like “Speed dial” home page. It is reported to consume fewer system resources than the major general purpose browsers like Mozilla Firefox and Google Chrome.

QupZilla 1.8.1 is the first bugfix release since v1.8.0. It fixed:

  • reverted setting DNT header by default

  • autofill not working for some frames

  • saving speed dial in case of crash

  • open file in download option on windows

  • Internet Explorer bookmarks importer

  • building on Mac

Install / Upgrade QupZilla in Ubuntu:

The latest binaries have been made into PPA available for Ubuntu 12.04, Ubuntu 14.04 and Ubuntu 14.10.

Press Ctrl+Alt+T on keyboard to open the terminal. When it opens, run the commands below one by one to add the PPA and install the browser:

sudo add-apt-repository -y ppa:nowrep/qupzilla

sudo apt-get update

sudo apt-get install qupzilla

If you don’t want to add the PPA, grab the .deb package directly from this page.

After that, you can launch the browser from Unity dash and receive future updates by running regular update via Software Updater.
