Web browser

Download for openSUSE

Developer: Google Inc.


Chromium is the multi platform open source web browser which is the base of Google Chrome. The minimalist design is part of Chromiums major goal of becoming the tabbed web shell. Being built upon WebKit engine Chromium provides latest HTML5 and CSS3 features to its users.


  • multi-process architecture - each site instance or plugin runs in separate process which for end users means better security and stability
  • themes - makes chromium easy to fit into your desktop design
  • extensions - enhance the functionality of browser via HTML, CSS and JavaScript
  • preferences sync - keeping the same settings, bookmarks, extensions and theme over multiple machines
  • incognito mode - private browsing prevents storing history or cookies by visited websites
  • DNS prefetching - faster address to IP resolution


Besides the openSUSE builds from the Build Service (see the links in the box above), you can get stable, beta and development packages on Google's "Early Access Release Channels" directly from The Chromium Projects.


You can use Chromium to send screen content, web pages, video and music to TV through Chromecast. However, here are some steps before you can use Chromecast.

Step 1. Enable Chromium extension

By default, Chromium cannot discover Chromecast devices. You need to go to chrome://flags/#load-media-router-component-extension and Change it to Enabled. Then you restart Chromium.

Step 2. Allow ports in firewall

According to this article, Chromecast uses the following ports to communicate with PC:

  • TCP 8008, 8009
  • UDP 32768-61000

In openSUSE Tumbleweed and Leap 15, you need to config firewalld through command line or user interface. Search "firewall" and you should be able to find the firewall manager.

  1. Connect to your home or office WiFi, the same one as Chromecast connected to.
  2. Open Firewall Config application.
  3. Find your WiFi connection on the left list and select it.
  4. Change its zone from public (the default one) to home or work, depending on your case.
  5. Switch to Runtime mode.
  6. Modify the zone settings. In Ports tab, add rules as the screenshot shows.
  7. Switch to Permanent mode and make the same change.
  8. Reconnect your WiFi.

Step 3. Try to cast something

Then you can open Chromium menu and select Cast.... You should be able to find your Chromecast device. If not, visit Chromecast Help
