How do I prevent unwanted website/browser actions?

Since a year or so, I notice a lot more unwanted things happening with my browser while I am surfing the net. For instance:
-websites changing their address while keeping the appearance of a previous page. They then lead to other content usually.
-websites changing other open tabbed pages, and removing the possibility to go back.
-websites opening several instances of themselves, so you can't skip back one page, but have to skip several by jumping. Clicking back doesn't work anymore then.
-websites refreshing themselves due to advertisements.
-websites opening other windows(casino ads i.e.). These pop-ups never seem to get blocked.
-websites resizing the browser window.
I understand the best way to avoid things like this is to avoid some websites altogether. But is there really no way a browser can be made/configured to block actions like these for me?
I guess the problem is, that a browser can't differentiate a user-command from an unwanted script giving commands. Even so, there should be things that can be done.
For instance a button that blocks a website. If you can add a favorite page, why can't I add an "unfavorite" page just as easily? Next to that handy "star"button in the navigation bar, there should be a "block" button.
Another thing that comes to mind is some sort of "kill switch" for scripts. Right now I am looking at a tabbed page that keeps refreshing itself every so often due to the ads on it. Why can't I stop that with my browser? Just stop. That's all I want. There should be a way to kill the auto pilot and get back manual control.
I know there are things like adblock, flashblock and such. I just don't want to have to resort to third party addons and crap like that. Things like these should be built in options to increase security and give better user control and experience.
Even though browers are getting better and better(like the private browsing and such), I do get the feeling that I am in less control of what websites do on on my computer than ever before.
Anyone have any tips or thoughts for me? Thx.

How do I prevent a website from opening another window

A couple of websites I occasionally visit open up a second window to a spam website. I have put an entry in my Hosts file to prevent Firefox from connecting to the spam websites, so the second window is empty. However, it's still a little annoying.
I have pop-up blocking turned on. Is there anyway to completely block the opening of the second window?
If not, why not?

Thank you for taking the time to reply. I really do appreciate it.
Unfortunately, the link you posted tells me exactly nothing. My question is "How do I prevent a website from opening unwanted windows". These are full Firefox windows, just like you would get if you right clicked on a link and selected "open in a new window".
There are only two possible answers:
(A) To block unwanted windows, do this ________ (insert answer)
or
(B) It's not possible.
If the answer is (B) then the follow-up question is -- Why Not?

How do I prevent Adobe Website attempt to install Flash Player which freezes Windows e-mail browser.

For past several days, my Windows e-mail browser frequently freezes and must be closed. This occurs whenever message near top of browser states that Adobe website wants to install Adobe Flashplayer. Windows explanation states that termination is a result of Data Execution Prevention (DEP). How do I stop Adobe Website attempts to install Flash Player, or if that is not possible, what is a solution? I have uninstalled Flash Player in an attempt to resolve problem without success.

You can find a link and instructions for the last version of Flash Player compatible with PowerPC in this FAQ:
What version of Flash Player should I use with my Power PC based Mac?
For what it's worth, Apple itself discontinued support for PowerPC with their operating systems back in 2009 with the release of Snow Leopard. Regardless, I know its frustrating when your system is no longer supported. Hopefully the instructions I posted in the FAQ allow you to get Flash content running again.

How do I prevent unwanted paragraph style overrides when exporting an epub

I am having trouble controlling the size of a logo in an e-pub. Actually, it's only a problem with Amazon's Kindle which seems to insist on enlarging the image to the full screen width. So, I need a robust command in my CSS to override Kindle's preference. Seems easy. I placed the logo into my In Design layout in a picture box with the object style "frontmatterlogo" which should export into a div of the same name. Which it does. So far so good. However, In Design insists on creating a paragraph style override (see bold in the code below) which disregards the frontmatterlogo settings I've written in to my CSS in favour of it's own image settings which correspond to the size of the placed image. Currently, I've just put together a hacked solution by writing a class for para-style-override into my CSS. It's an inelegant solution but seems to work for all the other e-readers. But, as mentioned, it doesn't work on the Kindle.
Anyone have any idea what is causing these overrides and how I might prevent them so my div class can take over?

Thanks for getting back so quickly, Bob.
I'm using Version 5.5. I have basically the same problem when the object is anchored. In the case below, I created a new paragraph style for the line on which the logo would be anchored, also mapping to the frontmatterlogo entry in my CSS. This time, no paragraph-style-override is added but In Design still adds it's own image dimensions corresponding to the size at which the image was placed in the layout. This overrides the settings in my CSS and, I suspect, might be what's allowing the Kindle settings to take over as well. I had kind of resigned myself to fixing this in the code on a book by book basis, which is fine if the only images the book contains is a cover and a title page logo. But I'm worried about what happens when I have to create an e-pub from a photo-heavy book. You can see how it would be ideal to create a few specific object styles for different image situations in In Design and have them map them to specific div styles in my CSS. Basically it's a workflow issue. This would minimize the amount of after-the-fact coding our already swamped designers would have to do.
It's so obvious in the code where the problem lies, and so I just have a feeling that there may be a simple fix. If only I knew why In Design felt obliged to specify the image size.

How can I prevent Mail from applying actions (moving/copying/flagging/marking read) to duplicate messages?

I use Mail to check multiple accounts. When I receive the same e-mail in multiple accounts, actions applied to an e-mail in one account often (though not always) affect duplicate messages in other accounts.
Example 1
Someone sends an e-mail to both me and my wife. Mail is set up to check both accounts. If I open the message in my Inbox, it marks it as read in my Inbox as well as in my wife's Inbox.
Example 2
For historical reasons, I have chosen to have all my e-mail forwarded (by the server) to a second account, to be used essentially as an un-touched archive of all incoming mail. If I manually move a message from my main account Inbox to another mailbox, the destination mailbox will end up with 2 copies, one from my main account Inbox and the other from the "un-touched archive" Inbox (which has obviously now been altered unintentionally).
Does anyone know of a way to prevent this behavior. I can manage my own duplicates. I don't want Mail to do it for me.
(Btw, I already have the "AlwaysShowDuplicates" option set using "defaults delete com.apple.mail AlwaysShowDuplicates")

There are certainly many ways of organizing things so that Mail never has to deal with multiple accounts and duplicate messages (separate user accounts, separate computers, separate mail clients, etc., etc). That's just not what I was asking. I'd like to know how to fix Mail's behavior when it does have to deal with multiple accounts and duplicate messages.
I was hoping there might be another hidden preference or something (and by the way my original post should have said "defaults write com.apple.mail AlwaysShowDuplicates -bool true", instead of the "defaults delete ...")

How to create an auction website using Action Script 3

I want to develop an auction website for a flash assignment but I don't know how to go about doing it. Can I get some suggestions?

If you don't know what you need to create for such a site, then you should try to think of something else that you might have some idea of how to go about doing. Maybe you should talk to other students or your instructor to get some ideas and to figure out what kinds of things you need to be able to demonstrate with your assignment.

When i open a new tab in Firefox, the yahoo website will open automatically in this tab. How can i prevent any website from opening in my new tabs? I just want to open an empty tab.

You click on new tab, a new tab opens, but the tab is opened as the yahoo homepage.
I accidentally downloaded the yahoo toolbar as malware the other day. This toolbar is really imposible to remove. It's not in the sofware add/remove menu, i've tried with several anti-malware sofware, they didn't succeed.
Now, i already made the toolbar invisible, but it still has a place in the firefox menu at the top of the browser, and like i said, it keeps opening itself in a new tab.

A new tab opens by default as a blank tab (about:blank).
If that isn't the case then an extension has changed that behavior.

How do I prevent a website like Drudgereport from automatically reloading?

''Duplicate post, continue here - [https://support.mozilla.com/en-US/questions/806866]''
Sometimes my wifi connection is choppy (darn that microwave popcorn!) and I hate it when I'm in the middle of reading the links in Drudge and it reloads....sometimes shifting the layout a bit or just hanging while it waits for some adserver to respond.
Is there any way to stop this from happening? Tried Freezing the tab. And for some reason, firefox is not preventing this page from automatically reloading like it does others.
Any ideas?

You can also use a simple JavaScript bookmarklet to stop the refresh timer. You need to repeat that with every reload unless you change the code to a Greasemonkey script that runs on that site.
<pre><nowiki>javascript:clearInterval(timer);void(autoRefresh=null);

How can I prevent unwanted applications reappearing in the Mac OS X Lion dock?

Every time I log out and back in, or shut down / restart the computer, three applications that I have previously removed from the dock (Mission Control, the App Store and FaceTime) reappear in the dock. I see someone else on a different forum is having exactly the same problem.
I have no problem removing them during my session - I can right click 'Remove From Dock', and they disappear in a little puff of smoke. But when I log back in, there they are again.
This is not critical, but it's quite frustrating! Any ideas on how to stop this happening?
Thanks,
Helen

1. Find the file in: /library/preferences/com.apple.dockfixup.plist
2. Trash it
3. Restart
And done.
Basically, if you trash that file you tell your mac to build a new dock file and it will work fine after that. Had the same problem but this solved it for me.
Also, back up the file beforehand, just in case.

How can I prevent videos from automatically starting when I load a web site?

Recently web sites have begun not only showing me the first shot of a video, but starting the video automatically when the page loads (or when I scroll down to the part of the page where the video is located). This happens on various news sites (nytimes.com), facebook, and other places. How can I prevent the autostart from happening?
I've got AdBlockPlus and NoScript enabled, although I whitelist many sites in NoScript. Videos used to wait for me to click an arrow in the middle (like a "play" button) to start; some still do, but most don't. (I believe an add-on is responsible for the play button, but I don't recall which one.)
Any suggestions?
Thanks.

The chosen answer is not an answer at all.
The question remains unanswered: How does one prevent unwanted video content from playing automatically on web websites? The problem is most notable on news sites such as ABC News.
It is really, really, really really really, really, really, really really really, really, really, really really really irritating. More irritating, in fact, than when people cut and paste a word a dozen times to emphasize it.
MORE IRRITATING THAN WHJEN PEOPLE USE ALL CAPS OUT OF FRUSTRATION BECAUSE NO ONE SEEMS TO LISTEN OR TO CARE THAT I AM SLOWLY LOSING MY MIND BECAUSE EVERY FLIPPING WEB PAGE IN EXISTENCE PLAYS VIDEAS THAT I DON'T WANT TO WATCH.
More irritating than repeatedly stating the same thing over and over and over and over... wait. I already illustrated that tautology. Never mind.
Does anyone have an answer? If there is no answer, and the powers that be at Firefox have decided that we have no choice, then state so. If those who decide what HTML "is" have decided that individuals have no power to opt out of video content on any given web page, then say so.
If Obama is to blame, then say so. If Bush is to blame, then say so.
But don't say, "the web [page may be using HTML 5 to play video" because THAT is a NON-ANSWER, let alone the "best" answer.

How do i prevent history from being cleared? prevent privacy browsing?

How do I prevent privacy browsing and/ or prevent history from being deleted from son's computer?

Note that removing or disabling "Private Browsing" will not make it impossible to delete private data like visited websites (history) or cache.
There are a lot of ways to clear such data, either via [[Clear Recent History]] or directly by deleting the History in the Library or sidebar.
Private Browsing makes it easier because all data is kept in memory and nothing is saved to disk, so nothing needs to be removed.
If you want to see which sites have been visited then you should look at others means outside Firefox like a router or firewall with a password protected logging feature that can't be bypassed or a program like [http://www.wireshark.org/download.html Wireshark].

How do I prevent browsing and search data from being forwarded to Google by Mozilla, while still using Mozilla's Firefox as my default browser?

I do enjoy using Mozilla's Firefox as my default browser, BUT, I don't enjoy the details of my life, to include my Internet activity, to be archived by Google, or anyone else, via Mozilla's/Firefox's sharing of my Internet browsing and/or search engine activity with any aspect or facet of the Google organization. With all of this said, my question is, "How do I prevent browsing and search data from being forwarded to Google by Mozilla, while still using Mozilla's Firefox as my default browser?"

Firefox's default behavior includes no automatic interaction with Google.
We do use Google as default search engine and to report web forgery in the 'help' menu, but no data are sent to Google without your knowledge, and you can change your preferred search engine at will.
However many websites themselves make use of Google Ads which do cause interaction with Google when you load the webpages. This is visible in status bar and happens in any browser. The [https://addons.mozilla.org/en-US/firefox/addon/noscript NoScript] add-on for Firefox can largely save you from this problem.
If you see things happening otherwise, please reply with details on what you see.
