Ubuntu Oneiric Internet
Internet applications enable you to make full use of your Internet connection. Web browsers, Email clients, Instant Messengers, and more are included in this category.
Mozilla Firefox is the ubiquitous web browser. Based on open source components, it is trademarked and cannot be altered or re-distributed with any change that involves the name or trademarks. Install the current version:
sudo apt-get install firefox
Adblock Plus plug-in (block ads in a web page)
Adblock Plus blocks ads that appear in web pages. It is an important tool to limit tracking and undesirable website elements, as well. You can subscribe to a free filter service, and can add to the block list individual ads and website elements with a single click.
sudo apt-get install xul-ext-adblock-plus
- You can also add this extension from Firefox -> Tools -> Add-ons -> Get Add-ons -> Search All Add-ons -> AdBlock Plus. (This method will also ensure that automatic updates are installed by Firefox.)
- Recent versions of Adblock Plus allow the display of a large number of "partner" ads unless you disable this undesirable behavior:
- Firefox -> Tools -> Add-ons -> Adblock Plus -> Preferences -> Filter preferences... -> Allow some non-intrusive advertising (unticked)
Because Adblock Plus appears to now be creating holes in its own blocking service, it is probably worthwhile to stop automatic updates and only update Adblock Plus selectively (in case the developers in the future decide to create even more holes in the plug-in's blocking capability without the corresponding option to disable the behavior).
NoScript plug-in (controls scripts)
The NoScript plugin is considered one of the most important security measures for browsing the Internet. Most viruses and trojans gain access to computers from the Internet through scripts. This plugin allows you to choose which scripts to allow and blocks the rest.
- Add this extension from Firefox -> Tools -> Add-ons -> Get Add-ons -> Search All Add-ons -> NoScript. (This method will also ensure that automatic updates are installed by Firefox.)
- NoScript has a long of websites on its "whitelist." It is important to review this list and remove the websites for which you don't wish to automatically allow scripts (I remove them all).
- Firefox -> Tools -> Add-ons -> NoScript -> Preferences -> Whitelist
- A large number of websites use multiple locations/URLs to assemble their webpage content, a process which is blocked by NoScript's ABE (Application Boundaries Enforcer) function. I have found it necessary to disable ABE in order for most of my websites to function correctly.
- Firefox -> Tools -> Add-ons -> NoScript -> Preferences -> Advanced -> ABE -> Enable ABE (unticked)
- Many websites now use aggressive pop-ups to place advertising in front of the actrual content. While NoScript can block these ads, there will be a "placeholder" still blocking the content unless you turn off the placeholders:
- Firefox -> Tools -> Add-ons -> NoScript -> Preferences -> Embeddings -> Show placeholder icon (unticked)
- Most websites use scripting extensively these days, so that you may need to "Allow" a website in NoScript. To block the individual undesirable elements of the website, use AdBlock Plus.
Bookmark Favicon Changer plug-in
In the newest versions of Firefox, there are some bugs regarding the Favicons (the small icons that appear in the address bar) and the Bookmark icons. This plug-in will restore the icons that get erased (leaving a blank dotted box) or allow you to choose your own Favicons / Bookmark icons.
- Add this extension from Firefox -> Tools -> Add-ons -> Get Add-ons -> Search All Add-ons -> Bookmark Favicon. (This method will also ensure that automatic updates are installed by Firefox.)
RefreshBlocker plug-in (prevents redirects)
RefreshBlocker allows the user to decide which websites (and pages) will be allowed to redirect (based on META tags within the webpage). Although Firefox (as of version 3.5) blocks all directs by default, the behavior is not customizable; it is therefore preferable to turn off the Firefox redirect control and use RefreshBlocker instead.
- Add this extension from Firefox -> Tools -> Add-ons -> Get Add-ons -> Search All Add-ons -> RefreshBlocker. (This method will also ensure that automatic updates are installed by Firefox.)
- Turn off the Firefox automatic redirect blocker:
- Firefox -> Enter about:config in the browser location bar -> right-click on "accessibility:blockautorefresh" -> Toggle to change the value from true to false
Video DownloadHelper plug-in for Firefox
The Video DownloadHelper plugin allows the download of videos (including Flash videos) from sites like YouTube.
- You can add this extension from Firefox -> Tools -> Add-ons -> Get Add-ons -> Search All Add-ons -> Video DownloadHelper. (This method will also ensure that automatic updates are installed by Firefox.)
User Agent Switcher plug-in for Firefox
Now that Firefox is the world's leading web browser, this plug-in should no longer be necessary. Still, there still exist a few old web apps that will only run on IE (and for them this plug-in may be useful). The User Agent Switcher plugin allows a browser to masquerade as another browser, allowing (most of the time) browser-specific content to be displayed.
- You can add this extension from Firefox -> Tools -> Add-ons -> Get Add-ons -> Search All Add-ons -> User Agent Switcher. (This method will also ensure that automatic updates are installed by Firefox.)
Unplug Download Management
The UnPlug add-on lets you save video and audio which is embedded on a webpage.
- You can add this extension from Firefox -> Tools -> Add-ons -> Get Add-ons -> Browse All Add-ons. (This method will also ensure that automatic updates are installed by Firefox.)
Lucifox (eBook reader extension)
Lucifox (Lucidor for Firefox) enables e-books to be read and e-book catalogs to be browsed in a Firefox window.
- To install, go to the website and click "Download Now."
Java Runtime Environment (JRE) for Firefox plug-in

Note: You must accept the license to use this product.

Moonlight plugin for Firefox
Moonlight is part of the Novell Mono project that is an open source implementation of Silverlight (the Microsoft multimedia presentation platform). It is based on FFMpeg. It is made to work best with the Firefox 3 web browser, as a plugin (but also works with other mozilla browsers). Version 2.3 is available as a plugin for mozilla-based browsers:
sudo apt-get install moonlight-plugin-mozilla
- The stable version 2.4 is available here. The Moonlight 3.99 plugin (compatible with most Silverlight 3/4 content) is here.
- Netflix under Moonlight
- Netflix streaming requires both the capabilities of Silverlight 2.0 and Digital Rights Management modules. Although the current version of Moonlight 2.0 will run most Silverlight content (including Netflix content), Netflix has not yet released Digital Rights Management modules for Linux. Please contact Netflix directly for further information or sign a petition.
- An HTML5 Netflix plugin (currently being developed by Google for the Chrome browser) may soon be available. Another alternative is the Netflix Android app which can be used in a virtual Android environment.
FireFTP for Firefox
FireFTP is a Firefox extension for FTP transfers.
Turn off browser bar drop-down list in Firefox
This is the most frequently asked problem regarding Firefox. To turn off the location browser bar drop-down list (and therefore not show your browsing history):
- Firefox -> about:config (in the location browser bar) -> browser.urlbar.maxRichResults -> right-click -> Modify -> set value to 0
Turn off SSL certificate name in address bar
In newer versions of firefox, the validity of the SSL certificate associated with a website is displayed as a color-coded background to the Favicon (the small icon displayed in the address bar). However, Firefox currently also displays the name of the site issuing the SSL certificate, which can be annoying, since for most sites this is a duplicate of the domain name (which then gets displayed twice in the address bar). To turn off this behavior:
- Firefox -> about:config (in the location browser bar) -> browser.identity.ssl_domain_display -> right-click -> Modify -> set value to 0
View Firefox cache
In a new window/tab, enter about:cache in the Firefox address bar. You can view and save individual elements (from all open windows/tabs) in the cache from there.
