Thanks for posting this!
I would only mention that your definition is incomplete for this -
Contextual selector A type of Style Sheet Selector that
and that it's most often referred to now as a Descendent selector, not a contextual selector. It's basically the same as the Compound selector that you have already defined....

I'm getting unwanted tabs popping up in firefox. How can I prevent this?

New tabs are appearing at random times in my Firefox window. I can leave firefox open, and come back to the computer and have new tabs that have appeared. I can be actively working in another tab, and have a new tab appear.
I think this started when a game from popcapgames.com was downloaded to my machine. This game was not ever run on the machine - as far as the downloader will admit.
I tried to access Spybot Search & Destroy from this machine, and I suspected that I was not getting the correct site, but a forgery instead. I used a different machine to get Spybot onto a memory stick and installed it onto my machine. I've run it several times, and it has removed considerable amounts of spyware from this machine.
But, I'm still getting unwanted Tabs popping up.
I've verified that the pop-up blocker is still set in firefox.

Do a malware check with a few malware scan programs.<br />
You need to use all programs because each detects different malware.<br />
Make sure that you update each program to get the latest version of the database.

I have been trying to work on my homework all afternoon, via NAU's blackboard system. I am continuously getting booted out of the system, with an error stating "Data execution prevention". How can I prevent this from continuing?

If you are wondering why you are not getting any responses, it is because you have vented a complaint without any details that make any sense or give anyone something to work on.
If you want help, I suggest actually detailing what has happened, with versions of software etc. Anything that would let us assist.
As a start I am guessing that you have not really got the hang of "How it all works". Firstly download the Pages09_UserGuide.pdf from under the Help menu. Read that and view the Video Tutorials in the same place. A good addition would be the iWork 09 Missing manual book and something to help you learn how to use your Mac.
If there are specific tasks you need help with:

I open safari and one site takes me to their app in the store automatically. How can I prevent this?

some sites that use flash (or other issues) dont want you trying to view the site in your browser on an ios device, because they know it will not be a good experience - they detect your device, and if it is an ios device they want you to use their app instead of your browser.

Look for a program called BlueHarvest. I'm not sure if it still works with Mountain Lion.
I believe your file server can be set up to handle the metadata files, but I suppose that would depend on the Server software and your IT staff.

When creating a comment summary, I want to end up with a pdf of comments only. In addition, I do not want author, date, time, or page number to show in my comments summary. How can I do this?

When creating a comment summary, I want to end up with a pdf of comments only. In addition, I do not want author, date, time, or page number to show in my comments summary. How can I do this? I do a lot of reading, and when I summarize my comments, I like to save these comments in a larger document I compile over time. I typically create a comment summary, export it to a text editor and find myself having to delete author, date, time, page number, and anything else that is not the raw and net comment. It would save me some good time if someone showed me how to do this. The reason I do not want any additional information is because it simply adds stuff I do not need in my compilation of summaries for large amounts of papers over time.

What you're describing can't be achieved using the built-in comments summary function of Acrobat, but it can certainly be done if a custom-made script it used to generate the summary because then you're in full control of what's included in it and what's not.

in Safari, certain
characters like hyphens and apostrophes appear as
black diamonds with question marks.
This has nothing to do with fonts. It usually happens when your encoding is set wrong for a specific page. Panther Safari did not show these diamonds, but just displayed nothing, so people get the impression something has changed, but it really hasn't.
In Safari, I'm using Unicode (UTF-8) as my default
encoding. Is this setting correct?
Not if you keep running into pages with black diamonds. It would be better to set your default to Western ISO Latin 1. The black diamonds will probably go away.

I don't know if you can prevent it at all. The same ting happens to me in other apps - not just web browsers. I realize that since it's a web browser, there might be something that you don't want someone else to see if they use your iPad, so If it bothers you that much, close Chrome when you are done with it.
Double tap the home button to bring put the multitasking display. Find the Chrome app preview window and drag it up off the screen to close it.

Gratuitous kernel panic on my iMac G3 running Tiger. How can I prevent this

Ok, I know I probably shouldn't have installed Tiger on my G3 iMac so you don't need to remind me. However, it runs pretty good and I hardly ever even see the beachball spinning when I ask it to do something. What I am shocked, shocked by is the ridiculous amount of frequency that I end up with a kernel panic that gives me the 'gray screen' telling me I have to restart my Mac. I have been able to keep this down to a minimum by pointedly only running programs and commands one at a time with a good sized pause in between but even with that I am diappointed with how often it happens. Call me a heretic, but I think it would have killed Apple to stick with their classic OS framework rather than go to UNIX. I would like some tips about things I could do to minimize this occurence above what I already do. It really ***** to have had to reinstall Tiger about 3 or 4 times since I upgraded and have to change up the screen position, dock, desktop, mouse, screen saver, and reinstall all my programs after my iMac has croaked and finally accepted another reload of Tiger.

I'll ignore the major portion of your post which comes across as a rant and try to stick with the title: "kernel panic on my iMac G3 running Tiger. How can I prevent this?"
Kernel panics are usually caused by bad or marginal RAM or RAM that isn't seated properly, or by buggy or damaged software or drivers. In the past, problems with marginal RAM for Macs has shown up when people upgraded to new versions of the OS -- which might fit your situation.
Although your CPU is slow, you have lots of RAM, so Tiger should run OK, if the RAM is not defective. You don't mention how much free space you have on your hard drive. Typically you're going to need at least 5 Gig free to give Tiger breathing room.
Running a system maintenance utility like Yasu would probably also be beneficial:

What does the hardware test for your Mac say about your system? This might help us determine if there is a hardware cause for the kernel panics.

My child accidentally rented a movie on Apple TV. Is there a way to refund the rental if we don't watch it? How can I prevent this from happening? Is there a way to password protect future purchases?

Did you try Parental Controls?

See if that does the trick: I think there's a way for you to request a password for purchases, but still be logged in.

Back up all data.
Launch the Keychain Access application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ Open LaunchPad. Click Utilities, then Keychain Access in the icon grid.
Select the login keychain from the list on the left side of the Keychain Access window. If your default keychain has a different name, select that.
