Then shalt thou understand righteousness and justice,
And equity, yea, every good path.

Firefox has been the default Ubuntu Web Browser for many years. The non-profit Mozilla organization cares more about your privacy than profits and has the only other browser engine available on Linux not based on Chromium. Firefox features Enhanced Tracking Protection and fingerprinting blocking by default. See all the Privacy and Security Setting here. To ensure fast start up and the ability to use Mozilla extensions, a non-Snap version of Firefox is included in C4C Ubuntu.
Literally thousands of add-ons are available for Firefox, categorized and searchable on this website. Extend it’s capabilities, theme it, make it work the way you do. Computers4Christians only installs one add-on by default; the FoxFilter parental control (subscribe if you find it useful).
Built-in organizing allows you to categorize your bookmarks on the fly (while you’re browsing). Hit the “Choose” selection to save in an existing category (C4C loaded-up Firefox with hundreds of categorized bookmarks already), or select “Organize Bookmarks…” to use the Library where you can backup, restore, import, export, add, delete and rearrange bookmarks at any time.
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, etc. By default, the top search engine is set to Duck Duck Go. 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.

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 less complicated, C4C includes Gufw for a nice graphical user interface. Read Set Up a Firewall with Gufw from It’s FOSS.

Thunderbird email client 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.
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.
Thunderbird supports POP and IMAP email. See webmail (AIM, Gmail, Hotmail/Outlook, Yahoo!, etc.) solutions on this page. Also see RSS basics and How to Subscribe to News Feeds and Blogs. Visit the Thunderbird Homepage, Community Page, and Add-ons Pages.
