FF 8 short black screen during startup

Not a big deal but a black screen and then inverted (negative) image appears when I start Firefox. This happens very fast, in less than half a second but it is noticeable and I haven't seen it before with previous versions. Is there any fix for this? Thanks!

Try to disable hardware acceleration.
*Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
If disabling hardware acceleration works then check if there is an update available for your graphics display driver.

  • Black screen during startup

    I get a black screen during sturtup of my MacBook Pro (April 2011): the backlight are on, but the grey screen with the apple doesn't appear.
    Then, after a few, the login screen appear, and after I log in I can use my MBP normally.
    I tried resetting the SMC, but nothing changes. I thought to reinstall OSX (I have 10.6), but I realized that I can't if the screen is black.
    I've also tried the Apple Hardware test, but I don't see anything.
    Any idea or suggestions?

    Apparently I solved by resetting the PRAM.

    i get a black screen during windows 7 installation on bootcamp 5.0.1 , it wont install

    Hi wb2009,
    I haven't found that the TV would be an issue, but did find an article that states to not have extra USB devices connected.
    Boot Camp: Windows installation boots to black screen with blinking cursor
    http://support.apple.com/kb/TS4536
    The Windows installation may boot to a black screen with a blinking cursor. This can occur if you use a USB optical drive or USB Flash drive for the Windows installation and another USB device is also connected to the computer.
    There's another article that mentions Windows XP or Vista that may apply.

  • Black screen during windows 7 install on 27inch iMac

  • Apples update didn't work for me: Boot Camp: iMac displays a black screen during installation of Windows 7

    Boot Camp: iMac displays a black screen during installation of Windows 7 - Apple Support
    I have followed each of the steps listed in the link above with no success.
    Prior to adding the extra drivers I was able to start the Windows install process up to reformatting the "Windows" Bootcamp drive. After that the computer would go through some instal processes and eventually restart. After the restart the screen would go black. The black screen lead me to the  Apple Support link above dated March 5 2015. After going through steps listed in the link above, I get an error message stating that the D:\Sources\instal.win. file cannot be located. I am forced to restart the computer at that point and theWindows install process attempts to start again but always ends up at the same point.
    Note: I am installing windows 7 Pro from a DVD. I scanned the AutoUnattend.xml file and noticed that it refers to "Windows 7 ULTIMATE" but not "Pro" or any others that I could see. (see below). Could that be part of the issue?
    Any feedback would be greatly appreciated.

    Hi
    Look not good dude I think its an serious hardware issue
    I checked the movie and cannot hear a beep when the notebook passes the POST (power on self-test). So for me it looks like something wrong with the hardware
    But did you try to connect an external monitor in order to check if something would be visible on second screen? Check this
    You could also try this:
    Disconnect AC adaptor, remove the battery, wait some time (3-5 hours), then connect both parts and try to power up the notebook. If this fails, well in such case have no many other ideas. Ohhh wait maybe you could check the RAM modules. Try to power up the notebook using one module in each slot

  • Black screen on startup early 2008 macbook pro

    I am very disappointed with Apple right now. My early-2008 15 inch macbook pro shows a blank/black screen on startup. The hd runs fine and I can dim and undim the backlight on the screen but it stays black/blank.
    I talked to an Apple rep and she told me that it was probably my graphics card (which I asked her specifically about when I researched and found many other people like myself with the same issue and then the lawsuit that came as a result). Of course, Apple no longer replaces the graphics card (like a true business person would) as of December 2012 even though they know the cards in the macbooks pros are defective. The Apple rep told me that I would have to take it in to a Apple tech to get it "officially" diagnosed as the graphics card being bad (which would cost me @$150 just for it to be looked at!) and then I would probably still have to pay for the repair!
    Of course this happened in the middle of the week while I was in the middle of working on a sermon and other presentation projects. So I had to do my best to try to work from scratch without access to the info on my hd because the graphics card is defective.
    Apple, you know the card is defective so please just replace the card! I'm not asking for any perks or upgrades! Just to be able to use my Macbook Pro that, up until now, I have been bragging about and telling everyone how happy I was to switch over from windows!
    HELP!! HELP!! HELP!! HELP!!

    If you experience distorted video or no video . . . take your affected product to an Apple Authorized Service Provider or Apple Retail Store to determine which service and support options are available. If you plan to visit an Apple Retail store, make a reservation at the Genius Bar using http://www.apple.com/retail/geniusbar/
    No, it has not cost anything in the past.
    Note: as of Dec 7th 2012, it is unlikely products qualify for this extended repair coverage.
    That does not mean it's an automatic "no."

  • Black Screen During Gameplay and not High Demand Renders?

    Hi, 
    The computer I own has been having issues with games that it previously had no problem with. 20-30 minutes within a session the screen will go black and audio will continue momentarily. The only way out of this issue is to hold down the power button for a reset. I have updated my drivers and cleaned out any dust with pressurized air. But the problem still continues. The strange thing is that I use Photoshop and After Effects for my work and there is no issue. Need help!

    Hello masinic2,
    I understand that just recently you started getting freezing and a black screen during game play and are looking to resolve it. I am providing you with an HP Support document: Using Microsoft System Restore (Windows 7), which will walk you through restoring your computer back to a point in time where you did not have this issue. This will not affect your personal files, but it will affect any applications you have installed or settings you have changed between now and the time you restore back to. You will have to reinstall or redo the changes that are undone during that time frame.
    Please re-post if you require additional support. Thank you for posting on the HP Forums. Have a great day!
    Please click the "Thumbs Up" on the bottom right of this post to say thank you if you appreciate the support I provide!

  • Black screen on startup with a mouse pointer but can't do anything???

    Hello,
    I've read all the posts in regards to this topic.  Nothing has worked.  I have my brothers HP laptop with Windows Vista.  I thought the Hard Drive (HD) crashed because all I had on start up was a black screen with a cursor.  When booting I am given the option to start up in Safe Mode, Safe Mode with Command Prompt, and Safe Mode with Networking.  No matter which one I choose I get the same thing - black screen with a cursor.  I can move the cursor around.  Nothing happens when I hit Ctrl+Alt+Del.  When I hit the **bleep** key 5 times the widow comes up about the Sticky Keys - the paragraph asks me if I want to enable them but does not give the the option to click on a "yes" or "no";  My only option is to click the X to close the window.  If I use the short cut keys for the Windows Utility (windows key = u) I get an error message basically saying it can't find the file.  
    I have a Rocketfish HD Enclosure for SATA drives.  So, I removed the HD from the HP and plugged it into my other computer (an Acer) with the enclosure.  I ran Norton AVI & Spy Sweeper.  Norton removed & resolved 2 Trojan viruses.  My brother was not using Norton or Kaspersky, or McAfee - or any other AVI software that is worthy... obviously - he got 2 Trojans!  Spy Sweeper ran overnight and half a day (16 hours) - didn't finish and found nothing during that really long time span.  He apparently partitioned his HD himself.  When I hook it up to my computer it shows up as 3 different HD's.  One appears to be just back up files and that part of the partition is FULL.  One has pretty much nothing on it, and the other appears to be the main one he is/was using because that's where all the program files are.  I can successfully navigate through all 3 partitions.  I copied all his documents, pictures, files, Mp3's, etc to my own external HD.  I can see his entire OS is there... his HD is FINE as far as I'm concerned.
    I put it back into his laptop and the same thing happens... black screen with cursor.  
    I can get into BIOS.  In BIOS I ran the HD diagnostic, it says to replace the HD.  I let it go ahead and do the memory diagnostic test in BIOS for the heck of it and of course that's fine - he's got 4gb.  
    I did something else in BIOS - restoring?  It restarted and did nothing...
    I tried hooking up MY own personal old HD (with entire OS still on it) via my SATA enclosure  to his laptop and still nothing... so, it won't recognize any OS.
    I have ruled out - in my belief that his HD is okay.  Especially now that I have removed the viruses.
    I have not figured out what the problem is though.  I can't get in - it seems to not recognize the HD - it won't boot from the HD - I can't get into C:\ from anywhere to even try to get up Windows Explorer.  
    I'm thinking other hardware failure... fried motherboard?
    So, I'm not completely computer illiterate.  But, hardware trouble shooting is not something I've had much hands on experience with.  I can write lines of code in several languages... but hardware troubleshooting does not seem to be my best subject... (I'm still in school for my BS in IT).
    My brother thinks his laptop is trash - I think his HD is okay - he may still be able to use it as an external HD if he gets an HD SATA enclosure like mine.  But, this poor laptop has survived Hurricane Gustav - where he lost his home in Baton Rouge, LA and therefore I'd like to fix it, I know I can fix it, but I have to know what's wrong with it in order to fix it...
    I'd appreciate any useful suggestions!  If it is a motherboard issue... I wonder how hard they are to replace
    P.S. - it's a HP Pavillion dv6500 Entertainment PC
    P.S.S. - I'm going to open it all up tomorrow & clean it - who knows the last time he cleaned it, if there's a lot of dust in there it could be a big problem.  Just running it today it got VERY hot and the fans seem to be running very loud (as compared to my Acer laptop).

    A hard drive if it has failed will sometimes allow you to boot into windows but may not work completely (Eg: In a scenario, where system partition ;where windows is installed works fine but logical partition of hard drive has gone bad).
    On certain conditions, if the hard drive is on verge of failure may/may not respond completely. I would suggest you to run a diagnostics using Seagate Seatools which works on any hard drive irrespective of manufacturer to actually confirm if your hard drive has failed.
    Also, any hard drive can fail in spite of it been 1yr old or 1day old as its all manufactured in bulk and most of it comes from China

  • Please Help: iMac black screens after startup logo + spinning wheel no cursor).

    Hi, guys.
    I'm in a fair bit of a desperate situation; my iMac's screen seems to shut down every time after the white startup screen. The Apple logo appears, & the progress wheel begins spinning, then after a while - when it would usually then go to the gray login screen - it would, instead, go black. I can tell that the machine is still on (I can still hear it clicking as it does during processing) but I'm unable to determine anything else. Nothing is visible on the screen - not even the cursor - it's as if the display had turned off completely. I'm not sure if the login screen sits beneath that black screen (I have tried to log on by typing my login details in blindly, but even if it does log in, it's hard to determine what state the computer is in without seeing the screen.
    I have tried the PRAM reset (holding CMD+OPT+P+R) during both the white startup screen, & the black screen to no avail. It seems unresponsive because I don't hear any additional chimes that I've been told should be heard during a PRAM reset attempt. I can't even be sure that the command is being inputted correctly because the light on my wireless keyboard remains off during the process.
    I've tried rebooting over & over again; the results are the same.
    The steps that led to the problem occurred thusly:
    1 - I was trying to clear some memory from my current session, so I scanned through my active processes, quitting anything which seemed to be eating up considerable amounts of memory.
    2 - One particular process I quit was 'launchd' which was functioning under my profile username.
    3 - After quitting launchd, all opened apps seemed to close, & it looked like I was forcibly logged off the machine. The screen froze during this point, & I decided to do a hard reboot to log back in.
    4 - The problem began after this hard reboot; startup seemed to occur as per usual; white screen > apple logo > progress wheel > and then suddenly, a black screen where the login screen should be.
    I've shown a flashlight into the screen while it's black & it seems well & truly like the display has shut down while the iMac continues in the background. I have had issues relating to my screen going black before, but they were random & intermittent; they didn't occur without fail during the exact same time immediately after startup, & could be remedied by using the CTRL+OPT+EJT keys.
    I am on an iMac 2010, 27", using I believe Lion OSX. I am unable to recall additional specifications while the problem persists.
    Could anybody please help me? I'm quite desperate; I was in the middle of some urgent work that I need to get back to as soon as possible.
    Thank you I'm advance to anyone with advice on how I can go about fixing this.

  • HELP! Black screen after startup after Yosemite installation

    Urgent help please.
    I Have a late 2010 MacBook Pro and today installed Yosemite. It appeared to install ok, but now on startup it gets past the apple logo screen then just goes to a black screen with a cursor. I have attempted a safe boot, and it manages to get to the login screen, but it won't accept my password, it just keeps on loading the login screen over and over. Would love an answer please...I am completely puzzled!

    Ok, I am a couple of days ahead of you. I had exactly the same issus on a mid 2010 mid MBP. Mine failed after the install, although it worked fine for a few minutes untill it went into Sleep. When it came back on it was in color But you could not really see, Another reset and all went black.
    After an hour on the phone with support on Sunday who suggested trying a system management reset. Solved nothing. I went to my Genius apt on Monday.  Two hours and 15 minutes waiting in line And finally I got my Genus.
    Again a nice guy trying to help, but other than pulling the connector to the screen and getting back my comprised color negative screen no real progress. "I know it sounds like a strange coincidence but maybe you display went bad."  Well perhaps you can get hit by lighting twice in a row while humming "Oh, What a beautiful morning" but I did not think so.
    I was more lucky back at home. I recently installed an SSD, so I took it out and booted with the old drive and booted 10.9.5. Display was fine. So this proved the issuse was Yosemite install. Here is the good news, when I put the SSD back in everything was great. i know you can't do exactly what I did. Here is what I suggest..
    I believe the issuse is bad video driver with Yosemite during the install.   rreinstall Maverick or boot from another drive with OPTION. . I believe it will work fine. Then if you are lucky perhaps your Yosemite will work as mine did...
