A lot of windows appear, when i watch Altera's html5 trainning lesson, but ie do not

when i watch Altera's online trainning lesson(the address is http://www.altera.com/customertraining/webex/MemInt_CN/presentation_html5.html), Sometimes, the lesson will pop another webpage to show something(for example, click 5.2.2 or 6.7 when timeline reach the end, there will pop out one webpage) when i use firefox, no matter on PC or linux, there will come out a lot of same webpages which make my fedora down, but indeed it should be just one. however, ie just pop out one webpages

Sometimes Firefox will attempt to open a link numerous times if it is a type that normally cannot be displayed in Firefox but which has somehow become assigned to Firefox, for example, by choosing Firefox in the Open/Save/Cancel dialog for a download.
To see whether this is the problem, you can reset your preferred download handlers by renaming a settings file. Here's how:
Open your current Firefox settings (AKA Firefox profile) folder using either of the following:
* "3-bar" menu button > "?" button > Troubleshooting Information
* Help menu > Troubleshooting Information
In the first table on the page, click the "Show in Finder" button (on Windows: "Show Folder")
Leaving that window open, switch back to Firefox and Exit, either:
* "3-bar" menu button > "power" button
* File menu > Exit
Pause while Firefox finishes its cleanup, then rename '''mimeTypes.rdf''' to something like mimeTypes.old
Start Firefox back up again. Any improvement in how the site manages windows?
If you decide to continue with the new file, you may need to reset some preferences, such as how Firefox opens PDFs.

    Saw this solution on another post about an iPad in a school enviroment. Might work on your iPad so you won't lose everything.

    ‘iPad is disabled’ fix without resetting using iTunes
    Today I met my match with an iPad that had a passcode entered too many times, resulting in it displaying the message ‘iPad is disabled – Connect to iTunes’. This was a student iPad and since they use Notability for most of their work there was a chance that her files were not all backed up to the cloud. I really wanted to just re-activate the iPad instead of totally resetting it back to our default image.
    I reached out to my PLN on Twitter and had some help from a few people through retweets and a couple of clarification tweets. I love that so many are willing to help out so quickly. Through this I also learned that I look like Lt. Riker from Star Trek (thanks @FillineMachine).
    Through some trial and error (and a little sheer luck), I was able to reactivate the iPad without loosing any data. Note, this will only work on the computer it last synced with. Here’s how:
    1. Configurator is useless in reactivating a locked iPad. You will only be able to completely reformat the iPad using Configurator. If that’s ok with you, go for it – otherwise don’t waste your time trying to figure it out.
    2. Open iTunes with the iPad disconnected.
    3. Connect the iPad to the computer and wait for it to show up in the devices section in iTunes.
    4. Click on the iPad name when it appears and you will be given the option to restore a backup or setup as a new iPad (since it is locked).
    5. Click ‘Setup as new iPad’ and then click restore.
    6. The iPad will start backing up before it does the full restore and sync. CANCEL THE BACKUP IMMEDIATELY. You do this by clicking the small x in the status window in iTunes.
    7. When the backup cancels, it immediately starts syncing – cancel this as well using the same small x in the iTunes status window.
    8. The first stage in the restore process unlocks the iPad, you are basically just cancelling out the restore process as soon as it reactivates the iPad.
    If done correctly, you will experience no data loss and the result will be a reactivated iPad. I have now tried this with about 5 iPads that were locked identically by students and each time it worked like a charm.
    ~~~~~~~~~~~~~
    Try it and good luck. You have nothing more to lose if it doesn't work for you.

  • Why my notebook sometimes blacks out, in Windows 7, when I watch video online or just browse some web pages which contains quite a lot pictures?

    Why my notebook sometimes blacks out, in windows 7,  when I watch video online or just browse some web pages which contains quite a lot pictures?
    1. I am not sure whether it is the problem of the graphic hardware, relevant softwares or the system itself.
    2. I am not sure whether browsing a webpage with a lot pictures would make the graphic hardware, or other hardwares if possible,  massively burdened and then just crash.
    3. Or if possible, is the reason that the heat dissipation doesn't work well?
    I am looking forward to any replies that might be helpful. Really appreciated.

    it could be heat, not enough RAM, but you don't tell us enough.
    There is no reason to assume this is anything other than running Windows natively btw.
    Browser  of course matters probably the most.
    I like IE10 now, but use to use FF until recently. I'd like Chrome except for a few concerns I have over using it, it can eat up a lot of RAM and it builds up HUGE disk cache if you don't clear history and cache on exit and run CCleaner regularly ( good for all browsers )
    So assuming 64-bit and 4GB or more and core i5 or better...
    Also make sure Wiindow has 10GB of free space or more.
    Biggest concern is what happens afterwards and whether you have run a check of your hard drive (chkdsk on startup) or if the problem cascades and gets progressively worse on top of the first - like do you have to do hard restart or able to bring up Task Mgr and kill or better yet, Resource Mgr and see if you have any thread locks.
    Safari is not well versed in multithreading and handling what you want to do and are doing. IE9 isi usually good but I found it could not handle a lot of tumblr photo streams and sites. Try Chrome. With Firefox, use noscript, blashblock and see how it goes.

  • Cmd window appears when running sqldeveloper.exe for some users

    All,
    I'm wondering why a cmd window appears when I double click the sqldeveloper.exe executable?
    This is a Windows 2008 server.
    Also, when the user that installed SQL Developer runs it, the cmd window has no text in it but when other users are logged into the server and run the same executable, they have a lot of messages appearing in the cmd window similar to:
    at org.apache.log4j.xml.DOMConfigurator.doConfigure<DOMConfigurator.java:616)
    What I'd like to do is NOT have any cmd window appear when the users run sqldeveloper.exe

    There are two sqldeveloper.exe files. The one in the root of the sqldeveloper installation folder doesn't produce a console; the one in <sqldev>\sqldevloper\bin does.

  • Invisible windows appears when trying to open a new window. These windows are listed in the Window list, but I cannot switch to them or close them. This also occurs when I try to "View Source". This was not a problem prior to my 6.0 upgrade.

    I cannot open a new window for FireFox.
    Invisible windows appears when trying to open a new window. These windows are listed in the Window list on the menu, but I cannot switch to them or close them. This also occurs when I try to "View Source". This was not a problem prior to my 6.0 upgrade.
    The Downloads Window cannot be accessed either.
    This is very annoying. Is this a bug? Or is there a fix.

    If anyone is reading this still looking for what caused the issue and how to fix it here is what I discovered.
    The antivirus program our company uses, Bitdefender Antivirus Plus, was causing some of the PDF files not to open. After troubleshooting the different modules and settings the culprit was..
    Scan SSL in Privacy Control Settings. Turning it OFF solved the problem and all the PDF files that previously would not open now open just fine. This issue has been sent to Bitdefender for them to review. If you use a different antivirus program and are having this issue try locating the Scan SSL setting and see if turning it off solves the problem.

    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - If you can redownload it by:
    Downloading past purchases from the App Store, iBookstore, and iTunes Store

    Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

    The progress indicator in version 11.0.1.2 does not appear when a song or podcast starts. It may or may not appear during play. How do I make it appear so I can start a podcast in the middle of the program?

    No errors in error console. No effect using *. I tried using the dns name of my localhost both in the Firefox URL and in the javascript and I get exactly the same. I have spent a huge amount of time looking into this issue.
    One thing I noticed is that if I use the examples on the internet (http://arunranga.com/examples/access-control/preflightInvocation.html or http://saltybeagle.com/cors/) they work in the same browser. These examples however, are accessed through HTTP proxies.
    I am wondering if the issue has to do with using the same hostname just with different ports.

    I use Final Cut Pro X to make YouTube videos.  The sound is great when I watch the videos on certain computers, but muffled on others.  How do I fix this?

    You don't. You can't control how other computers or browsers play back the footage.  The best you can do is export a master file that plays great on your computer.  What youTube does with it, or how other computers play it back is out of your hands.
    Just like me with broadcast TV shows.  I deliver the most pristine version I can to the network. But then they convert it to a digital file that they then beam out to cable and satellite providers, who then compress it again to play on their systems. And then it arrives at grandma's house and plays on her TV. I have no control how my grandma receives the signal, nor how her TV is set up.  Unless I am nice and tweak things when I go visit. But I can't do this at every house that might want to watch my show.

    I'm in Panama trying to watch World Cup games in Univision but it's not streaming to Panama. How do I change location? i have mini I ipad

    Since location of an internet connected device is quite easily determined by IP address, it is very unlikely you will be able to do anything about that if it is indeed being blacked out in Panama. Hit the app store and see what might be available to you in Panama. Univision doesn't have exclusive rights to the games.

  • What plugin or what else use to make cool small window appear when I move on to a link, displaying content of that link on en.wikipedia

    Hi,
    On my previous computer, I had cool feature on my Firefox working on en.Wikipedia.
    When I moved mouse coursor over link, automatically window appear with content of that link. Link was to wikipedia.
    This windows was realy cool, cause I could move it, or click "more" so more content was displayed on this window. I could display few such windows on one page I was currently. I could move each where ever I wounted.
    So beeing on one page on en.wikipedia I could see explanation of words used in this page, also used from wikipedia, just moving over this word, which was link, and I could display few such windows, that I could move through whole page.
    I used older version of Firefox, on different computer, on Windows Vista laptop.
    I searched for such plugin, but I couldn't find it. I find one kind a similar, QuickWiki, but much simpler, and much less functional.
    I don't know how to find it. It was valuable tool for me. I used a lot of Wiki. Using this tool my job was much easier, as I didn't have to go to new page each time I wan't to check meaning of that word.
    Please, help me if you know what to do or what tool to use.
    Best regards,
    Artur

    Thanx :) It's even more than I wanted.
    I can see web page in small window, without opening new tab, just moving my mouse over a link. Cool, really usefull. Thank you.

  • Applications Window appears when start up

    Last week I had a problem with my printer not being on line, after some unguided troubleshooting, I got the printer back on line. Don't ask what I did, I don't know for sure.
    But, now when I boot up OS 10.4.7, the Applications Window appears with the desktop in the background. I have been unable to find a way to keep the window from appearing on start up.
    Any help?

    You might have inadvertently set the printer to open every time you log in or restart.
    Go to "System Preferences", then click on "Accounts", then click on the "Log In Items" tab. Look to see if your printer is listed there. If it is, just highlight it and then click the minus button to remove it. Items listed there will open every time you start up or log in.
