I always thought everyone who surfs internet would know about browsers, but amazingly many of the people I know, who would get the fastest computers for surfing the internet, and would stay up there for hours, months, years and still don't know what a browser is or anything but internet explorer. No wonder internet explorer is the most targeted browser by the mean and savvy hacker because many people who surf the internet only know the "e" icon and nothing else. Well, I don't know much about security on the internet, but I always tried new stuff, and this is for firefox which is the most popular BROWSER beside the almighty (nagger) "e".
I only know of 4 browsers which they're all nice, Opera actually has the most features but it doesn't support CSS3 like the primitive ie6,7,8. For viewing all the websites that contain the newest scripts and technologies, firefox, chrome or safari should be used. Firefox is the most popular browser in 2009, although majority of businesses only support ie.
firefox & shadowbox pop-up
Chrome & Shadowbox
safari & shadowbox
Opera & Shadowbox
All browsers installations are the same and easy, not like ie8 (asking tons of questions, tons of updates, if it's the... ... greatest and latest why updates as soon as you install?) . I don't use ie8, just installed it to test the webpages to see what errors loading it would see. It's the most paranoid and nagging web browser I have ever encountered (questions and questions while browsing). Anyhow, this is for my father, aunt, uncle, and brothers & sisters who got stuck on ie6,7,8 and extremely lazy to try any other browsers.
Installing firefox.
Well, first go to the firefox website, download the latest installation file
Click download file and choose to save or run, I recommend run if you don't know how to save a download file or where the file would be saved if you save it. Depends on which browser you're using now, you may get different screen to save or run.
Just choose a folder (a place for the file) for the file to be saved in, I choose desktop, it's easiest place to find in case I experience amnesia and forgot.
When it's done, go to desktop and it sould be there, to access the desktop, minimize all the open windows and when you see all the icons, then the firefoxxx.exe will be there.
Now just double/single click the icon (circled) and it will asked to be installed. MS famous "are you sure", may be not since it's firefox 
I could uncheck the always...
To be fast and easy, just select standard as default.
launch firefox for the first time. This screen is actually the updated screen.
Configure the browsers. Most browsers have the same options for configuring the way we save downloaded files, the way we book mark, encoding languages, plugins and stuff. The most important ones are flashplayer, pdf reader from Adobe, javascript from Sun, windowmediaplayer from Microsoft, Quicktime from Apple. Just install these for the browsers to play flash videos, pdf, java aplets, apple and windows movies.
FIREFOX OPTIONS
Click on Tools dropdown menu, select "Options"
Click Main tap: Under Home page, enter your favorite url (http://www.yahoo.com or google.com or...), if click use current page, then the address of current page will be your home page. Home page is the page when we click the house icon, it will come back to it. The nex one is Downloads, the default is the folder "my documents\Downloads" but you can browse to a specific folder for all download. I would make a folder on the desktop call "mydownloads" and make it the default, it's easier to find since it's on the desktop.
The next tab is "Tab", this one to configure how to display firefox windows, it's a great way to surf with tabs. I would select all except "warn when closing multple tabs", I hate nagging questions.
Tabs are the best feature in browsers, we don't have to open many links with tons of windows on the windows toolbar, now we can open many links in the same windows and displayed by tabs. We can add new page with the "+" icon, rightclick a link and select open in new tab. Since we set up tab as above, all links will open in tabs, it's better to see all tabs and looking for them in seperate windows down in the windows toolbar.
The next tab is "Content", this is where you set to control all pop-ups, enable javascripts, java, fonts, fonts sizes, preferred language (I use defaul "en").
You can add exception for blocking pop-up windows for a certain website by clicking allow pop-up when you're there at the website or enter them manually.
The next tab is Applications, I leave it alone.
The one after is privacy, this one allow you to clear the history of your browsing webpages, especially if you go to the "adult websites" often, clear it so your significant other can't see where you've been or your work. To clear history, you can do it from the Tools drop down menu.
Next tab is "Security", I checked everything except Master Password. At home, on my desktop, I would allow remember passwords for logging in some non-important websites, but never for banks, merchants or anything to do with money transactions.
Final tab is the "Advanced" tab. General, all browsers will have a box checked for being a default browsers, if you uncheck this, they won't ask every time you use them. I only check for firefox because it's my default browser.
Advanced/Network: If you can surf the internet, I leave it alone.
You can check to see how it's connected to the internet, auto-detect proxy should be the one.
The next one is the most annoying, nagging one "update", I always uncheck installed_addons, checked the "ask_me".
Final Advanced tab is Encryption. I just leave everything as default.
BOOKMARKS
Well, this is the part where my aunt, uncle have problems with, we need to know how to bookmark, organizing bookmarks, import/export bookmarks. All browsers should have a personal bookmark bar on top for easy accessing. With Firefox, we can even have the yahoo bar add-on which many yahoo people like.
How to bookmark. All browsers now have a little star or icon next to the address bar for quick bookmark of the current page. With Firefox, it's on the right side of the address bar. Just click it, it saves the bookmark, when it became yellow, click it again to edit the bookmak link and a pop-out window appear for options.
we always save in the folder "bookmark toolbar" (the bar on top under the address bar for easy accessing), if we want to put the current bookmark in a folder inside the "bookmark toolbar" then select new folder.
rename the newfolder
After renaming the folder, we should see the folder appeared on the bookmark toolbar an when we click the folder, the bookmarked webpage name should be in there in the drop down menu.
Organize Bookmarks: Sometimes we need to backup or restore bookmarks from one computer to another. Click Bookmarks dropdown menu. Select Organize Bookmarks.
A pop-up screen will have import/export tab with dropdown menu, we can import/export in 2 formats, JSON or HTML. The default export file for Firefox is *.JSON but we can output to HTML for other browsers to import easily. Now, import/restore means loading a bookmark back up file to the browers, export/backup means save current bookmarks to a file. In this case, we restore a bookmark file that we backed up a few days ago, again we need to browse for the file we want to import/restore from.
Again, it will ask if you're sure because it will replace all existing bookmark, click OK if you're sure.
After we restored the backed up bookmark file. All the folders for the bookmark toolbar are loaded.
If we want to export our bookmarks to a file for future use, select export from the bookmark menu and select a folder for the file to be saved, again, we like the desktop for easy finding and accessing. It will show the date in the bookmark file for clarity.
Well, for other browsers, we can import/export to html files.
By the way, this is the basic tutorial for people who do not know how to use the browsers, for other advanced features, search the web or go to the browsers website to learn.
Cheers,
