I just upgraded my Firefox program and now a group of black lines running 10-15 deep are appearing on my monitor from time-to-time

I just upgraded my Firefox program to a new version and immediately I started seeing a group of black lines running 10-15 deep running across my computer screen while on the Web. As I scroll down they sometimes disappear. Then they reappear. It doesn't happen all the time. But often enough.

Contact Apple. That sounds like a hardware issue in the graphics circuit.

  • JUST UPGRADED TO FIREFOX 4 AND NOW JAVASCRIPT NOT ENABLED EVEN THOUGH IT SAYS IT IS

    when I enter data on a website I get this response...previous to firefox upgrade it was ok

    I just had a similar problem and it reminded me of trying to install a logitech wireless mouse a while back. Nothing I could do to make it recognize the driver... until I ran across a website that told me that antivirus and firewalls might prevent it. So... AVG Free just updated itself earlier today... FF4 would only startup once after reboot, then start and show in task mgr but no window(s)... Uninstalled AVG new version. FF4 starts up every time. Reinstalled older version of AVG Free and now everything seems to be OK again. Hope this helps!

  • I just upgraded to firefox 6 and now cannot connect to the internet. IE still works fine but firefox won't connect. Any suggestions on how to get the new firefox to connect to the internet?

    I just upgraded to ff 6.0.1 via an automatic push. Since then, ff hasnt been able to connect to the internet. Error message:
    Firefox can't establish a connection to the server at www.google.com.Firefox can't establish a connection to the server at www.google.com.
    IE has no trouble connecting to the internet.

    After upgrading, your firewall may not be recognizing the new Firefox version and is not allowing it access to the internet. On your firewall progam's allowed applications list, remove Firefox, then re-start Firefox, try going to a website, your firewall will detect the new version of Firefox, then give the permissions needed for Firefox to have internet access.

  • I just upgraded to Firefox 7 and now it doesn't start anymore.

    Today I installed the latest version of Firefox(7.0.1). After I installed it, I had to restart my Firefox. I clicked the 'restart now' button and it closed my browser. However, it did not restart my browser. In fact, it didn't do anything. If I click on the firefox button now it doesn't do anything.
    Any help is appreciated.
    Hope this made sense. (English is not my native language)

    Ah, it is working now. Thank you very much.
    Firefox.exe was still running in the Task Manager. I closed firefox.exe there and tried opening Firefox again. It now worked perfectly.
    Thank you very much for your help fmdeveloper and finitarry.

  • Just upgraded to Firefox 8 and now a page works incorrectly, but is OK using IE and Chrome

    http://www.readingfilmandvideomakers.org.uk/Resources/videos.htm
    works OK with Internet Explorer, but gets out of sync selecting videos using the thumnail images. It used to work with firefox 7 but I have not tried it with the latest web page change. When testing using files on my PC some of it worked but the Toy Run video would not play via my embed from YouTube. Uploaded it will not display the correct videos

    I don't know, but every time my browser prompts me to update, I do. This is the first time I have had any drastic changes to the browser. Sorry for the freak out. I immediately starting reading the help topics AFTER I sent this message. I guess I should have done that first. The topics have helped me get everything mostly the way I like it. Thank you though for your fast response.

  • Just upgraded to firefox 4 and websites are now taking ages to load, there were no problems when I downloaded the upgrade. Is there a fault with the new version of firefox?

    Just upgraded to firefox 4 and websites are now taking ages to load, there were no problems when I downloaded the upgrade. Is there a fault with the new version of firefox?

    Did you check your security software (firewall)?
    A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
    Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process.

  • I upgraded for Firefox 4 and now my simplePass identity protection (biometric scanner) on my laptop will not work. WHY? It still works with IE but I don't use IE.

    I upgraded for Firefox 4 and now my HP SimplePass Identity Protection (biometric scanner) on my laptop will not work. WHY? It still works with IE but I don't use IE. It worked with the previous Firefox version but now when I use the internet, it doesn't even acknowledge I have the scanner. When I run my finger over it, it opens the settings panel but does not allow use of the already saved information or allow new information to be entered. I need this corrected. Any suggestions?

    I asked this same question, and just received a response:
    "Thank you for contacting DigitalPersona. There will be no update releases
    for DigitalPersona Personal in the future. There will be no updates for
    Firefox 4 nor Internet Explorer 9. IF they work they work, if they do
    not work with DPPersonal, then you will have to decide to either keep
    DPPersonal and forgo Firefox 4 or IE 9, or vice versa. DigitalPersona
    is leaving the consumer market and is focusing on business applications.
    In fact, DigitalPersona Personal will not longer be supported after
    Mid-April of this year.
    We apologize for any inconvenience this might cause. Sincerely, Tech Team "
    In other words, there will be NO update.

  • I just upgraded to Firefox 4. Now my cursor doesn't "snap-to" the default position.

    I just upgraded to Firefox 4. Now my cursor doesn't "snap-to" the default button. I made sure it was newly recognized (by unchecking and rechecking) in
    Control Panel > Mouse > Pointer Options > Snap To: Automatically move pointer to a default button in a dialog box > Apply > OK
    But the Fox isn't cooperating. How do I get this working again?

    I'm afraid I don't understand how your reply relates to my problem. I'll type the words I don't understand in your answer:
    "default dialog button" (where do you find this?)
    "mouse middle-click button" (I have a wheel)
    "Global default" I don't know what that is, so, apparently, it doesn't apply to me.
    "IntelliMouse" I don't have this either, just an old, dumb "Dell mouse" ;-)
    "dialog box" is that what I'm hoping the cursor will be moved to? If so, how do I get it to move there on it's own? What's the purpose of "Snap to" if I have to move the cursor there myself?

  • HT2513 I have just upgraded to the icloud and now I am getting an error message on ical - saying "make sure the URL is correct", I haven't changed anything so why is it now an issue? any ideas?

    I have just upgraded to the icloud and now I am getting an error message on ical - saying "make sure the URL is correct", I haven't changed anything so why is it now an issue? any ideas? 
    The full message sasy "The calendar https:// cal.me.com:8443/principas/users/(server number) was not found on the server.  Make sure the URL is correct.

    10.6.8 cannot access iCloud's facilities - you can set Mail up manually and there is a hack which some people have used to sync calendars (see below) - you cannot sync any other type of data.
    This is the situation with iCloud and Snow Leopard:
    Your email, calendars, and 'Find my iPhone' will be migrated to iCloud. Contacts and Bookmarks cannot be migrated from a Snow Leopard Mac.
    Your iDisk, together with website hosting and Gallery, will continue to work as before until next June.
    Syncing of Dashboard Widgets, Dock Items and Keychains between Macs, and Mail Accounts, Mail Rules, System Preferences, Signatures & Smart Mailboxes between Macs & iOS devices, will cease altogether.
    You will be able to access email and calendars on the iCloud website at http://icloud.com provided your browser is reasonably up-to-date.
    You will not be able to sync contacts or bookmarks from a pre-Lion Mac.
    You will be able to enter the server settings for email manually in the Mail application and access your email.
    You will not be able to sync your calendars directly.
    Some people have been able to set up calendar syncing by using the method detailed here - this is an unsupported hack and may not be reliable, and may stop working at some future point.  BusyCal is an iCal-like calendar application with extra facilities: it can sync with the iCloud Calendar while running on Leopard, Snow Leopard or Lion.
    There appears to be no method of syncing contacts (though Address Book on a Mac can be synced with Google or Yahoo address books - I don't know how reliable this is).

  • I've just upgraded to V5.0 and now I have lost ability to 'open in new tab'

    I've just upgraded to V5.0 and now I have lost ability to 'open in new tab' whats happening?

    Thanks but I've reinstalled V4 until V5 is stable and more or less working the way I want to work - not the way some programmer thinks I should want to work.
    You know change is OK but only if it makes things better for the user Change shouldn't be made to make the developer feel good about his/her expertise. For me V4 was Good. V5 gives me too many issues to deal with - I just need a relatively simple browser (and I guess I'm not the only 1 out there that feels like this).

  • HT3529 I just upgraded to iphone 5 and now imessage don't work. it sends as sms. i've checked imessages is on in settings.

    I just upgraded to iphone 5 and now imessage don't work. it sends as sms. i've checked imessages is on in settings.

    Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new).  Try each of these in order until the issue is resolved.
    It might also be a good idea to contact Square for assistance.

    Be sure to start your iMac using its original grey System Install DVD: Insert that disc and start your Mac while holding the d key. At the Mac OS X Utilities screen select Disk Utility and format the hard disk. Select "Mac OS X Extended (Journaled)".
    Then, install OS X.

  • I just upgraded my apple TV and now when I rent a movie on iTunes, instead of it playing instantly, it takes 60 hours to load. Anyone else have this problem?

    i just upgraded my apple TV and now when I rent a movie on iTunes, instead of it playing instantly, it takes 60 hours to load. Anyone else have this problem?

    Apple Support, I have just purchased 3 movies 2 from my account and 1 from my wifes account and both systems are stating that it will take 2 days to download.  I have a FIOS 150 megabit per second up and 150 megabit per second down busiuness class fiber service to my location.  I have tested downloading 10Gbyte files from two other locations and both work fine.  I additionally went out and have tested doing speed tests (http://www.speedtest.net/) from over 10 other locations all over the US and all are over 75 magabits per second download speeds with a few hitting 100 and 125 megabit per second speeds.  What is wrong with your servers or your internet connection????
    This is VERY FUSTRATING!!!
    I have additionally tried to download them with my Apple TV and two different PCs all wired on Gigabit Ethernet with jumbo frames enabled.  I have tried differnet DNS servers also.  I can upload and download files to my office 50G in less than 1 hour.  I have also download movies from 2 other movie sites without any problems.

  • Upgraded to Firefox 23 and now my yahoo bookmarks don't have the option to open all tabs in a folder. How can I do this.

    The option to open all tabs in a folder is not available any more on my yahoo toolbar. On this computer and my home computer which I just upgraded to firefox 23 and that option disappeared. I need to open all tabs in a folder at one.

    Hi ziccs, is the missing feature to open a group of bookmarks all at once in separate tabs?
    I haven't explored the Yahoo! toolbar in detail, but it was just updated recently. I noticed the description "new user interface" on the versions page. You also can use that page to re-install the earlier version and see whether the missing function returns.
