Firefox is leaving bits of its menus all over the screen--how do I fix it?

Any graphic or menu that exceeds the boundaries of the Firefox window may leave bits behind. Example:
http://lordzox.com/temp/ff4litter.png
Over at the right side, you can see that not only did the bookmark display not get cleaned up _outside_ the window, but it even made the window controls disappear.
Refreshing the display will clear the mess outside the window; minimizing and re-expanding the Firefox window will clear it inside. But it just keeps happening.

Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
* Don't make any changes on the Safe mode start window.
In Firefox 4 [http://kb.mozillazine.org/Safe_mode Safe mode] disables extensions and disables hardware acceleration.
* Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

  • When typing, my letters go all over the screen, just happens with Firefox.

    After installing Firefox, when I type, the letters go all over the screen, instead of where I try to type them. I used to type without looking at the screen. Now I have to watch... my cursor disappears, and the letters I'm typing go into something I've previously typed correctly.
    == When I installed Firefox, and it happens constantly.

    Do you have that problem when running in the Firefox SafeMode?

  • When i open my computer I get the white screen with apple symbol and there are vertical lines all over the screen with green pixels and after a few minutes the screen gets grey and I get message to restart my computer what happens

    3 years ago I bought an IMac Desktop that I am using for a lot of things but the most important for dvd montage in Imovies and Idvd.
    Now today when I opened my computer I get as usual the white screen with the Apple symbol but there were all over the screen vertical lines with green pixels and after a while the screen gets grey and I get message to restart my computer using the power button or the restart button and when I do so each time the same is happening somebody can tell me what is happening and what caused this. This computer is my work and now I have no income anymore.
    On the Apple support site they are asking to enter the serial number and when I do so I get message it is wrong but it is the only one I have and I buy this computer in Cairo Egypt. I am living in Hurghada in Egypt for the moment. When I call the technical support of the shop where I buy it they are telling me that it is the hard disk or ram and that I probably lost everything on it and they are asking a big amount to repair.
    Can somebody advise me on this matter. Thanks in advance

    You can find the serial number either in About this Mc in the Menu bar under the , or it should be on a sticker under the foot of the machine.
    If you have the install discs, try booting from them, holding down the c key and then using Disk Utility to check the drive. 
    You can also boot into Safe mode
    To start up into Safe Mode (to "Safe Boot"), do this:
       1. Be sure the computer is shut down.
       2. Press the power button.
       3. Immediately after you hear the startup tone, press and hold the Shift key.
          Tip: The Shift key should be held as soon as possible after the startup tone but not before.
       4. Release the Shift key when you see the gray Apple and progress indicator (looks like a spinning gear).
    During the startup in Mac OS X 10.2 through 10.3.9, you will see "Safe Boot" on the Mac OS X startup screen.
    During the startup in Mac OS X 10.4 or later, you will see "Safe Boot" on the login window, which appears even if you normally log in automatically.
    Please post back with results,
    To leave Safe Mode in any version of Mac OS X, restart the computer normally, without holding any keys during startup.

  • Programs open up scattered all over the screen...can this be changed?

    I am new to a MAC as I recently go a 27" iMac. I am loving it, but finding some of the functions sort of odd. I have searched and searched for an answer, but have gotten noplace. I thought I would sign up here it looks like a great resource. I was also hoping someone could answer this for me:
    Do all mac programs open up scattered all over the screen? I was always used to a program opening and it was clear where the entire window was. On my mac, if I open, say Photoshop, the tools panel is along one side, then there is no canvas, but the layers panel, or others I have open will be somewhere on the right side. When multiple programs are open, it is really hard to tell which program I am currently in as it seems so messy. All the programs seem to open this way. Is this a feature that can be turned off, or is this simply the way it is?
    I am not sure if I explained this very well, but somehow I would like to be able to clearly see which program I am in, rather than have bits and pieces of the program randomly placed on the screen with no definite boundaries to tell me where the program ends. Maybe it has something to do with having such a large screen?
    Any help you could offer would be greatly appreciated! Thank you in advance.

  • I have a first generation iPad and the screen went completely green on me and locked up.  I was able to unlock it, but now there's a green haze all over the screen.  Anyone know what the issue could be and how I can get it fixed?

    I have a first generation iPad and the screen went completely green on me and locked up.  I was able to unlock it, but now there's a green haze all over the screen.  Anyone know what the issue could be and how I can get it fixed?

    Try this  - Reset 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 - let go of the buttons. (This is equivalent to rebooting your computer.)
    Out-of-Warranty Service
         If you own an iPad that is ineligible for warranty service but is eligible for Out-of-Warranty (OOW) Service, Apple will replace (Apple doesn't repair) your iPad with an iPad that is new or equivalent to new in both performance and reliability for the Out-of-Warranty Service fee listed below. (The replacement will most likely be a refurbished iPad in a brown box, however, it has a new screen, back and battery.)   
    iPad model
    Out-of-Warranty Service Fee
    iPad mini
    $219
    iPad 3rd, 4th generation
    $299
    iPad 2, iPad
    $249
    A $6.95 shipping fee will be added if service is arranged through Apple and requires shipping. All fees are in US dollars and are subject to local tax.
    Certain damage is ineligible for out-of-warranty service, including catastrophic damage, such as the device separating into multiple pieces, and inoperability caused by unauthorized modifications. However, an iPad that has failed due to contact with liquid may be eligible for out-of-warranty service. See http://support.apple.com/kb/index?page=servicefaq&geo=United_States&product=ipad

  • I updated my iMac to 10.7.3 and about an hour later the screen began to flicker with a gray line on the upper side, and it also flicker green and red small pixel lines all over the screen, mainly green.

    I updated my iMac to 10.7.3 and about an hour later the screen began to flicker with a gray line on the upper side, and it also flicker green and red small pixel lines all over the screen, mainly green. The computer froze with these pixels, so I shut it off and restarted it, and there were this green lines everywere. So I turned it off, and the next day I turned it on and it began to work just fine, but suddenly the same thing happened again, and when I restart the computer again there are these green and some red pixels everywere.
    I've read 10.7.3 is giving people many problems, but I never saw that it gave one like this. How can I fix this, or what will Apple do to fix this problem they caused me with their update.
    Thanks

    Contact Apple Service, iMac Service or Apple's Express Lane. Do note that if you have AppleCare's protection plan and you're within 50 miles (80 KM) of an Apple repair station, you're eligible for onsite repair since yours is a desktop machine.

  • Blue or pink stripes appears all over the screen, can't do anything but restart with the button.

    I was watching Netflix and all of a sudden, blue stripes appeared in my screen. Then my page seemed to "split" in two and then come back to normal and then there were pink stripes all over the screen and I couldn't see anything else but stripes. I had to restart with the button. It restart correctly, I have been able to watch Netflix again but only on Chrome because on safari it would happen again everytime. Then, iPhoto opened and here we are again, stripes and image "moving", can't help but wait... Then the screen became all white and nothing. I tried to restart it again with the button, but it didn't even made it to the apple interface, juste the sound and then white screen. What is going on, Please? I really need my computer for work this isn't fun!

    After all this, you are at a white screen at startup and that is as far as it goes? What operating system are you using?http://www.macworld.com/article/2018853/when-good-macs-go-bad-steps-to-take-when -your-mac-wont- Also try this. https://support.apple.com/en-us/HT201295

    Sounds like a hardware failure. Make an appointment at an Apple Store to have your device examined by a technician. Or contact Apple Support.

  • Hi, my Macbook Pro just shut down for no reason. Before, there were black lines all over the screen. Then it shut down and it started to make beeps (3). What can I do?!

    I was using my computer just as usual, I was on Microsoft Words and doing lectures on the Internet. Then, out of nowhere, the screen froze and black lines appeared all over the screen and the computer shut down. The screen was all black, but I think it was still open because my laptop was doing sounds, three beeps. When it beeps, the little light that shows you when your laptop is open is bright, so the beeps and the light are synchronized. AND I DON'T KNOW WHAT TO DO, help me!!!

    There is a hardware problem. Possibly bad RAM. Please make a Genius Appointment and take it in for service.

  • I left my macbook pro closed and when I came back the screen had a huge crack all over the screen, anyone know why this could have happened?

    I left my macbook pro closed and when I came back the screen had a huge crack all over the screen, anyone know why this could have happened?

    Someone dropped something onto your computer.
    Someone pressed on the closed computer.
    Someone placed heavy objects on your computer.
    We can only guess since the someone was not us and we were not there when it happened.

    Does anyone know why the mouse cursor jumps all over the screen at times, especially if I am playing solitare?  Is it Yahoo games or my Apple?

    Is this a Magic Mouse you're talking about?
    If so there's already discussions about this here and maybe related to it, here.  Also google something like "jumping magic mouse" and there's no end of discussions on this topic

  • Satellite C600 - Cursor jumping all over the screen

    I was just issued the Satellite C600 and I cannot type without my curser jumping all over the screen. I've followed the advice from other threads with no success. "FN+F9" does not disable the touchpad, and there is no touchpad tab under Mouse Properties. In fact, when I search the whole computer for "touchpad" there is no response.
    Please advise!

    Hello
    Why you try to disable the touchpad?
    On Satellite C series there is a BIOS update that will solve this cursor jumping issue. There are already a lot of threads here in forum:

  • Curser is jumping all over the screen by itself

    my curser is jumping all over the screen by itself.  anyone else have this problem and if so how did you fix it?

    I have the same problem.
    The curser jumps all over the place either when typing on the keyboard on my totally tricked out 2012 MacAir (i7 2.0GHz, 512GB), or on the bluetooth keygoard that I have on my keyboard tray nearby: does it on both, apparently totally at random and quite often.
    It is realy annoying. I am trying to write a large book and this is really slowing me down.
    Various solutions are here on the forum related to old batteries bulging the keyboard, but it even does it on the bluetooth keyboard and the thing is only a year old, so that can't be it.
    Help!
    Thanks,
    Daniel
