Firefox There are a lot of Internet web browsers available, but none as configurable, extendable, or one might say personable as Mozilla Firefox. It's open source web browsing at it's finest. Mozilla is a non-profit organization dedicated to making your experience on the web whatever you want it to be.

Add-Ons Firefox has thousands of add-ons available [categorized and searchable on this website]. Extend it's capabilities, theme it, make it work the way you do. C4C only installs one add-on by default; the FoxFilter parental control.

Bookmarks Bookmarking a web page is as simple as selecting "Bookmark This Page" or pressing [Ctrl]+[D] when the web page has loaded. Alternatively, right-click anywhere on the main body of the web page to access drop-down menu selections that include bookmarking (click the "star" icon). Built-in organizing allows you to categorize your bookmarks on the fly (while you're browsing). Hit the "Choose" selection to save in a pre-existing category (C4C loaded-up Firefox with hundreds of categorized bookmarks already), or select "Organize Bookmarks..." to use the "Library" where you can organize and re-organize bookmarks anytime. Backup, restore, import, export, add, delete, rearrange... You can also try one of the many bookmarking add-ons to extend bookmarking capabilities even further.


Preferences Firefox Preferences gives you access to all sorts of settings. Control which plugins do what, what applications to use for which media type, how tabs are used, if and how your Internet activity is tracked and by whom. You can clear recent history too; over the past hour, day, week, or everything. Many more settings are available through the Preferences.

Search Bar By default, the top search engine is DuckDuckGo. But, this is easily changed and or rearranged with other searches. Click the icon to the left of the search box to switch to one of the other preset options, or choose “Manage Search Engines” to get many more choices. When you begin typing into the search bar, a dropdown menu of filled-in suggestions (based on popular searches from other users as well as your own search history) will appear. If you see one that fits, click it with your mouse.

Gufw A Firewall is your first line of defense from outside attack on your computer. Thankfully, most any *buntu (U/X/Lubuntu) comes with a firewall; IPTables. The firewall is not turned on; that is for you to do. IPTables is managed (via command line) by what's called UFW; Uncomplicated FireWall. To make it even more uncomplicated C4C includes Gufw for a nice graphical user interface. Gufw is free and open source software licensed under the GPL.

Thunderbird features tabbed mail view, filtering, message archiving, folders, smart folders, calendar and scheduler integration, themes, personas and add-ons. You can also use Thunderbird as an RSS and newsgroup reader. Filter email searches based on from, to, timeline, and attachments. Open multiple search keywords and jump between result tabs. Smart Folders can be used to combine your Inbox, Sent, and/or Archive folders from multiple email accounts. Create a Virtual Folder from your search conditions and edit the name and conditions. Load emails and searches in Tabs; reorder emails and search result tabs and drag them to different windows.

Junk Mail Thunderbird has extensive, adaptive "junk" mail classification(s). Train Thunderbird to get rid of junk by using the "junk" and "not junk" buttons on incoming emails. Then use the Junk Mail Controls to make the process of moving spam to the junk mail folder automatic. Thunderbird also automatically blocks remote image requests unless and/or until you tell it not to, depending on the sender(s). And Thunderbird warns you when you click on a link in an email that will take you to a different Web site than the one indicated by the URL.


webmail Thunderbird supports POP and IMAP. You'll likely have an easier time using webmail with a web browser like Firefox (see above). To use webmail (AOL, GMail, Hotmail, Libero, mail.com, Yahoo) with Thunderbird, you'll need the WebMail add-on. Or, see more Thunderbird webmail solutions on this page.
