Upon start-up homepage loads, Firefox freezes, and then the homepage refreshes continually.

After trying to do a google search through my google plugin. Nothing happens and the page continues to auto refresh. I tried to re-install the browser and the same thing happens again. When I try to disable addon's, a new tab opens to show the active/inactive add-ons and the auto-refresh happens on that tab too.

Start Firefox in [[Safe Mode|Safe Mode]] to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
*Do not click the Reset button on the Safe mode start window or otherwise make changes.

Firefox freezes and then greys out

After a short period of normal use Firefox freezes and when I try to click onto a new page the picture greys out partially. On the top of my screen it says that Firefox is not responding. My only course of action is close the program down. When I do that a small window opens Saying Firefox is not responding and gives the option of closing the program or waiting for it to respond.
I have tried removing Flash 11.3 and installing 10.3 - no change.
Tried removing and reinstalling Firefox - no change.
Disabling all plugins - no Change.
Tried restoring PC to an earlier point - No change

Unfortunately this sounds like a hardware failure. Run Apple Hardware Test in extended modeat least 2-3 times back to back. If errors appear then you have confirmed my suspicion. However if no errors appear unfortunatelyyou are not out of the woods l yet because AHT is not the more reliable test. If you do know know how to run AHT please refer to:

I click run, firefox downloads, and then the download window disappears and nothing happens?

I follow the directions on the site, wich say to click run. So I do, and it is supposed to run after its downloaded, but then when it downloads the download window closes and nothing happens.

Download a fresh Firefox copy and save the file to the Desktop.
* Firefox 6.0.x: http://www.mozilla.com/en-US/firefox/all.html
* Uninstall your current Firefox version.
* Do not remove personal data when you uninstall the current version.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
* It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
Your bookmarks and other profile data are stored elsewhere in the Firefox Profile Folder and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

Why does firefox freeze and then doesn't fully release from memory, but I have to End Process from Task Manager?

Frequently, Firefox for Windows (Vista) freezes up. I click on a link or try to go to another web page and nothing happens. The icon in the tab is just spinning, with Connecting. but it never connects. Then when I close it - if it lets me. I click to open it again and a window pops up saying that Firefox is already running, to please close it before launching it again. I have to go to Task Manager and End task from the Processes tab. It is also a resource hog including the Plug-In Container.

The pluging container opens up unnecessary copies as the cookies/history are cleared, this is a known issue, it might be what you are seeing, and it is hoped to be fixed in some future release of firerox.
There are some hangs affecting some users, with symptoms being high cpu usage, occurring as bookmark changes or syncing is in progress, there is a work around for that.
Firefox hanging as you close it see:

My iMac turns on and about 10 mins later it glitches and freezes and then the screen turns blue/green/white

My iMac turns on fine, but about 10 minutes later I can't use the mouse as the whole thing freezes. Sometimes it continues to move the mouse for a while but then glitches the screen (see first image). After that my screen turns blue/green/white and even purple as a solid colour (second image - changes to a different colour). I'm wondering what the problem is and can I fix it myself?

I have a similar iMac.
1. Be sure you have 4 GB of RAM.
2. Create a new USER wih Admin Rights
3. Don't add anything to the start up sequence.
4. Update all your apps. This is a big problem. Do it.
5. Use Font Book and verify your fonts. Delete any broken fonts.
6. Download and install Applejack. If you have to force a restart, press and hold command s. A black screen will appear. Finally it will say something about Applejack. Type applejack and run #1 and #2. Restart.
Don't run Applejack outside of safe mode. (Command s)
Come back and let us know how it is working.

My iPod touch's power button got stuck and then the screen went white.

My iPod touch 4G was a great device, until I stopped using it when iOS 7 came out back in 2013. Then eventually I got back to using it and then one day the power button started acting a little bit funny and then the entire button got stuck in the device. Eventually I tried to fix it so I opened up the screen and tried pushing the button back up. Then the worst happened, I touched something behind the screen and then the screen froze. Then the screen went white. I could do nothing as the power button was stuck in the device. Then it just sat there, white, until it died a few hours later. So heres my question,
What do I do?

See my reply in this discussion:
Turn on without Home/Power Button

In Firefox 31.0 a bug makes the browser freeze, and then I can't close tabs anymore, what may solve this?

Good afternoon. With the newest update of Firefox for PC (31.0), I have a problem that occurs almost every time I use the browser.
When trying to close a tab, it sometimes cause the browser to freeze during one minute.
Then a dialog-box appears on the screen. It says that the script "chrome://browser/content/tabbrowser.xml:2004" may be busy.
I can choose between two buttons in this dialog-box.
"Continue" which keeps the script running, in theory; though it just closes the dialog-box, makes the browser freeze again, and then the same dialog-box shows up.
"Stop the script" which ends the freeze; but then I'm unable to close tabs (I can still close the browser).
I also noticed that, when the freeze occurs, the content of the tab I tried to close changes to "New Tab".
When I restart the browser, I am able to close tab again, until the freeze shows up again.
The problem started to appear only when I updated Firefox to the 31.0 version (and I didn't add any browser extension in the meanwhile).
Does anyone have an idea of what I could do to avoid the problem? Thank you very much and have a good day!

In the immediate future you can try noscript or flashblock addons to block that script.
However upon more research in searching the current Firefox codebase: [http://dxr.mozilla.org/mozilla-central/search?q=tabbrowser.xml&case=false] it seems to be referenced in there, but I do not see a reference to the port associated. The port is usually used for media. I would not know how to start to troubleshoot this, but are there any consistent steps/webpages that cause this to start?
Does this happen in Safe Mode, please see [[Troubleshoot Firefox issues using Safe Mode]]? And does it happen in a fresh install?

Every time that I want to go full screen with an enbedded video firefox freezes and doesn't expand

Every time I try to go full screen with an embedded video or video game Firefox freezes and stop working

1. Update firefox to the latest version 2. and disable real player in menu->addons->plugins.
Recent crashes of certain multimedia contents (this includes Youtube videos, certain flash games and other applications) in conjunction with Firefox 13 are most probably caused by a recent Flash 11.3 update and/or a malfunctioning Real Player browser plugin.
In order to remedy the problem, please perform the steps mentioned in these Knowledge Base articles:
[[Flash Plugin - Keep it up to date and troubleshoot problems]]
[[Flash 11.3 crashes]]

Firefox freezes when loading some web pages then the computer locks up

Sometimes, when loading a website, the browser freezes. Then the computer locks up and I have to use the power button to turn it off. There seems to be no pattern to this problem. I'm also not sure whether or not the problem begins within Firefox, but a web page was loading every time it happened. It has only started happening this week.

I seem to be having a very similar, if not exactly the same issue. I'm using the latest production FF 11.0 release on Win7 64 and as with this not only does FF freeze, but I can't task switch, or anything. The one thing I've noticed is that when the lockup happens, it always appears to be loading some custom font from a CDN, if I breathe deeply and slowly and allow the request to complete everything seems to eventually unfreeze and I can continue, so maybe something to do with implementation of custom font loading?

Firefox freezes, if clicked the screen goes white and says firefox is not responding. How do I fix this?

At seemingly random times, firefox freezes, and if clicked the screen goes white and says not responding. At times it makes watching any video impossible. I have tried everything I've seen in help forums. I've removed and reinstalled firefox, adobe, silverlight, realplayer, and anything else forums have suggested. So far the only effective solution I've read about this problem is to switch to google chrome. I'd rather not do this.

Start your '''Computer''' in safe mode. Then start Firefox. Try '''Safe''' web sites.
Starting The Computer In Safe Mode;
If running, turn your computer off.
Remove any disks and thumb drives that are in your hard drives or ports.
Now start your computer but also;
'''Windows; '''Press the <F8> key repeatedly.
'''Mac: '''Hold down the Shift key.
'''Linux; '''Using the command line, Linux/Unix computers can be booted
into various run levels that determine which resources are loaded.
For example, "runlevel 1" is typically the equivalent to Windows and
Mac safe modes.
* Source; '''[http://encyclopedia2.thefreedictionary.com/Linux+Safe+Mode Safe Mode; Free Online Encyclopedia]'''
When the '''Boot''' menu is displayed, release the key you were pressing.
You must now choose what mode you want. The most used are;
* Safe Mode; The computer runs with only a minimum set of programs.
* Safe Mode '''With '''Networking; Same as above, but with internet access.

Firefox freezing, and eventually crashing when opening a tab?

Just yesterday this started, at first youtube videos froze the browser (but I could still hear them playing) and now I can't even open a tab without firefox freezing and just eventually having to end the process. It was working perfectly before yesterday.

Can you run Firefox in [[Safe Mode]]? If it functions properly in that configuration, then one of your add-ons is the culprit.
Also, please go to the [http://www.mozilla.com/en-US/plugincheck/ Plugins Check] page. Some of them are out of date and you'll need to update those first before we can proceed further.
By the way, you can view Youtube videos in HTML5 now instead of in Flash. All you need to do is to click the link at the foot of this page: http://www.youtube.com/html5 There's nothing to download and you don't have to fill in any forms. The player will switch automatically once you click that link.

Hello. When I connect my imac Start, as usual, comes the start signal and then the white screen with the load signal then nothing happens. What could be the problem?

Presuming you get the chime, most of your Mac hardware is working and has passed the first part of the power-on self-test.
If the screen comes on, basic graphics is working.
The dark gray Apple is not present inside the Mac -- it must be loaded from a boot device. If the dark gray Apple appears, at least one of your boot devices has some capabilities. The flower petal/gear moves while Darwin is initializing and loading. If it stops immediately, something is terribly wrong.
When the screen turns blue, Mac OS X has loaded and your graphics card transitions to Interrupt-driven operation. LoginWindow task draws the login screen, and Mac OS X is ready for login.
What could be the problem depends on where in the process it stops, and whether the power light is blinking.
