Try starting your iMac with the original DVD that came with the machine then launch disk utility to repair your hard drive.

Under Windows 7, 64-bit, Firefox intermittently will not open a new window - all I get is a grey screen, with a tiny part of my homepage displayed in the top left corner of the screen.

The problem began after a recent Firefox update. Occasionally, when I try to open a new Firefox window, all I get is a grey screen with a tiny section of my homepage visible in the top left corner of the screen. NOTE: Firefox stores all of these aborted attempts, as, whenever I close it and then re-open it, the first time I open a new window it automatically opens all of the windows that had originally failed to open.
== This happened ==
Every time Firefox opened
== on or about June 26, 2010

Got the exact same problem aswell, finally fed up with it now as i just started up firefox and 14 new windows opened because of this bug, luckily my computer can handle them but someone with a slower processor it would have been a nightmare, needs fixing ASAP.
Reverting back to 3.6.3 until this issue is solved. (link for anyone wanting to do the same below)

I have a small window quickly popping up and disappearing in the top left corner of my screen?

I apologize in advance if this has been covered elsewhere, but I have been searching and haven't found anything yet. And thank you for any help you can offer, it is greatly appreciated.
Every 15 seconds or so a small, empty window will pop up in the top left corner of my screen and then vanish instantly. It opens and closes in a blink, so quickly that I am not able to interact with the window in any way. However, it shows up momentarily as a firefox tab on my bottom panel, so I know it is a firefox problem.
It is only an issue because whenever it pops up I am exited from fullscreen if I am watching a video online, and anything that I am typing while the window pops up will be ignored.
I am currently running Linux Mint Olivia 15 Cinnamon. However, I had the exact same problem when I was running Windows 8. In both cases, firefox has been installed, uninstalled, and reinstalled, which does not fix anything. I have updated firefox since it started happening, which also did not fix anything.
It was very tricky, but I did manage to get a screenshot of the box while it was open.
The same question was asked here, but never resolved: https://support.mozilla.org/en-US/questions/953373

Does this only happen on specific pages?
Start Firefox in [[Safe Mode|Safe Mode]] to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Firefox/Tools > Add-ons > Appearance).
*Do NOT click the Reset button on the Safe Mode start window.

How do i fix a frozen mouse? It is stuck in the top left corner of the screen.

How do I fix a mouse that is frozen in the top left corner of the screen? I have tried rebooting and unplugging but it will not un freeze it.

I didn't even suggest that because I would have thought that would be the first thing anyone would have checked for! If you flip the on/off switch on the bottom of the mouse do you have a blinking green light? Whether you do or don't, if you are unsure of the batteries then replace them.

Whenever I reply to an e-mail the window comes up but without the paper airplane in the top left corner. The only way to send the reply is to close it and save as a draft. Then I can pull it up from Drafts and it has the airplane on it.

FF 7.0.1 on Mac OSX 10.6.8: I sometimes get the "unresponsive script" dialog box in the top left corner of the screen, so far out that I can see only the bottom right corner of the dialog box. Is there any way of re-centring it?

FF 7.0.1 on MacOSX 10.6.8 (not this machine!): I sometimes get the "unresponsive script" dialog box jammed into the top left corner of the screen so that only a quarter of it is visible.
Is there a way of re-centring the dialog box (in particular, when its top edge is off the screen)?
Thanks!

There is no way to preserve view preferences.Just remember or annotate the zoom % used in the package.
You may want to open an MS Connect item asking to add such a feature.
I can tell you it may not be implemented because a package may be opened on different size monitors.

A blank square appears at the top left corner of my screen after close the preferences window in Mac OS X

Whenever I open the preferences window and close, a blank square of 120px (aprox) appears at the top left corner of the screen. The square doesn't dissapear untill I exit from Firefox and reopen it.

When i move my cursor to the top left corner of the screen, I am automatically logged off. Is it a software problem or is it a feature I can turn off?

I don't think there is an option for logging off in the Hot Corners, but check Mission Control System Prefs, Hot Corners button. What is set in the top, left.

I reset my toolbars and now no longer see the "page back" or "page forward" icons on the top left corner of the screen

just loaded the new version of firefox. i went into "library" and told the computer to forget the mp3tube toolbar and it got rid of all the toolbars and also shows no search engine in new tabs, and has no page back or page forward arrows in top left corner of screen. how do i at least get the page back and forward function enabled?

Make sure that you do not run Firefox in Full Screen mode with all toolbars hidden.
* Press F11 to toggle full screen mode (Firefox/File > Full Screen)
If the menu bar is hidden then press the F10 key or hold down the Alt key, that should make the menu bar appear.
Make sure that toolbars like the "Navigation Toolbar" and the "Bookmarks Toolbar" are visible: "View > Toolbars"
* If items are missing then open the Customize window via "View > Toolbars > Customize" or via "Firefox > Options > Toolbar Layout" (Linux, Windows)
* If a missing item is in the toolbar palette then drag it back from the Customize window on the toolbar
* If you do not see an item on a toolbar and in the toolbar palette then click the "Restore Default Set" button to restore the default toolbar set up.

My 24"intel Imac Keeps going to sleep -it is hot to touch in the top left corner of the case -is something about to fail .

My IMac works for 30 mins without a glitch then starts putting itself to sleep every five minutes after that - it is getting hot in the top left hand corner - my guess is that something is on its way out - anyone had a similar issue before .

Ran AHT - nothing wrong.
Did a full cleanup and verify as well.
probem persists.
Fan is always going
might have to go to an applestore..

A white block appears in the top left corner of my screen - how do I get rid of it without restarting Firefox every time?

This seems to happen after I've used Firefox for a long time, or I've had several tabs open. The block covers all windows, whatever application I choose, and can't be dragged. I have to close Firefox and reopen it to remove it.

Where can I find the Mozilla SAVE/PRINT/Email tool bar? In my prior version it popped out in the top left corner of the screen.

Last week I had a system crash of my Windows 8 OS. When the system was "restored" all of my personal files (docs, jpeg, excl, etc.) were still available, but I can't figure out how to PRINT a DOC. Up until last week I had a Mozilla tool bar that included, among other functions - SAVE / PRINT / EMAIL.
Also, and I don't know if you can help me with this, but I also can't find my WORD, Powerpoint and Excel software???
We used new and official HP recovery disks.
Any insight would be appreciated.

On Windows 8, by default, Firefox displays an orange Firefox button instead of the classic menu bar. To switch between them, you can use either:
* right-click a blank area of the tab bar, or the new tab ("+") button > Menu Bar
* tap the Alt key to display the menu bar temporarily > View > Toolbars > Menu Bar
Did you get back all your Firefox data (e.g., Bookmarks, any Saved Passwords, etc.)?
Sometimes a system recovery/reinstall will stash your old data in a folder named
C:\Windows.old
If you have that folder, I know it takes up a lot of space, but I suggest keeping it around if you can because you may discovery things missing that you can recover from that folder.

I am logging into a website forum, and it loads with the icon in the top left corner of the tab, yet the window is blank!!! Please help

I have disabled all add ons and extensions, cleared my history, cache and cookies. Ihave also altered my firewall settings, can someone please help?

Just to rule out an issue with Windows, your router, or your ISP: does it work in IE?
Did you disable plugins by testing in Firefox's Safe Mode? If not, you might try that.
First, I recommend backing up your Firefox settings in case something goes wrong. See [https://support.mozilla.com/en-US/kb/Backing+up+your+information Backing up your information]. (You can copy your entire Firefox profile folder somewhere outside of the Mozilla folder.)
Next, use Help > Restart with Add-ons Disabled to restart Firefox in Firefox
[http://support.mozilla.com/kb/Safe+Mode Safe Mode]. Don't check any boxes in the Safe Mode dialog, just click the "Continue in Safe Mode" button.
Does the login work in Safe Mode? If so, it could be one of your add-ons, or it could be another setting or saved login that has become corrupted.

My iPad suddenly started displaying "Searching" up in the top left corner and now the ipad reboots itself after about 2-5 minutes.

My iPad suddenly started displaying "searching" up in the top left corner of the screen and the wifi symbol is next to it and I am connected to the wifi. Prior to last weekend it used to display Verizon and everything was fine. After about 2-5 minutes the iPad suddenly reboots itself. Can anyone assist with this. Thank you

Have you tried rebooting the iPad?
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 - let go of the buttons.

Why do new windows always open up pinned to the top left portion of my screen?

I have disable the application frame in Photoshop CC and now all new windows open up in the top left corner of my screen BEHIND all of the brush and tool setting windows. How can I change this?

Do you have your panels docked?
Could you post a screenshot?

My imac starts with a white screen, then goes black and a small white line just blinks in the top left corner of the screen?
