Firefox can't load websites but my Windows Explorer can. It was working before but now whenever I try to load a page it says "Problem loading page". What can I do to get Firefox to work?

Whenever I try to go on a website, Firefox says "Problem loading page." It won't load any pages. I tried uninstalling and re-installing but it still says and does the same thing.

- You can only sync an iPod to one iTunes library/computer. You can however, manually manage music and videos among different libraries.
Go to iTunes>Help>iTunes Help>Sync your iPod....>Sync You Device>Set up Syncing>Sync your device manually and follow the instructions.
- If y wnat to switch syncing libraries/computer see:
go to iTunes>Help>iTunes Help>Sync your iPod....>Sync You Device>Set up Syncing>Sync your device manually and follow the instructions.

If all the synced media like music is in the iTunes library of the second computer it is very easy.

How do I fix error code 401 - "unauthorized" I am taking an online class and the videos worked before, and now whenever I launch QuickTime, I get that error code.

I recently began taking an online class. We are required to watch multiple videos. I was able to watch the QuickTime videos before, but now whenever I launch the videos in QuickTime I get the Error code 401. My teacher does not know whats wrong, because I do have authorization to watch the videos, I am just not sure how to go about it.

You may try updating the same as a standalone download.

I cant get firefox to open at all it was working fine on Monday 1-09-12 but now whenever I try to open it it just says not responding I have uninstalled & re installed 3 times what do I do

My internet explorer works without any problem but I don't like using explorer I prefer Firefox please help if you can

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 and the updater process.
See:
*https://support.mozilla.org/kb/Server+not+found

Start Firefox in [[Safe Mode]] to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.

Firefox worked before, but now, when i try to start it, i get and error "We're sorry. Firefox had a problem and crashed". I tried to reinstall it, to reboot, nothing helps.

Hi,
Firefox worked before, but one time my system crashed. When I rebooted, Firefox won't start anymore. All I got is a pop-up window, saying We're sorry. Firefox had a problem and crashed. We'll try to restore your tabs and windows when it restarts. Problem is it never restarts. When I press Restart Firefox button, I get the same message. I tried to reinstall Firefox, to make a new profile, rebooted the system, nothing works. What can be done ? Thank-you.

Of course I checked firefox crashes. I searched and haven't found my problem. I used Firefox 5 when it happened, then, seeing it doesn't work no matter what I do, I upgraded to 6. The same problem. So it's not 5 or 6 related. Computer probably wrote something to hard disk when it crashed and now the file is corrupted and prevents Firefox from starting. I don't know what file (or part of the registry) is. I could erase everything, but that would mean I will lose every Firefox settings and I don't want that. Now I am using Google Chrome to write this. I miss my Firefox. :( What else can I do ?
This is the error I get when I try to start Firefox:

A few selection of websites after fully loading become blank and start an infinite loop of loading. I reinstalled firefox once already and the problem persists. What can I do?

A few selection of websites after fully loading become blank and start an infinite loop of loading. I reinstalled firefox once already and the problem persists. What can I do?

Sorry I do not know what the problem may be. 
If no-one comes up with better ideas of what causes this then my questions and suggestions:
What do you mean by an infinite loop ? 
The page loads and then goes blank. What exactly happens next, does the page fully load and fully display again before going blank, and repeat this cycle endlessly in the same tab.
You do say the problem persisted in safe-mode and you had looked at the basic troubleshooting article. Buy that you can stop the problem by disabling javascript.
* did you disable all plugins - and did you still get the problem then ?
As you mention disabling javascript stops the problem, have you tried with Java script enabled but
* block popups ON
* load images automatically OFF
* advanced options - ALL OFF What happens do you get the problem then or not.
While on this firefox site if I look at the error console Ctrl+Sift+J or Tools -> Error console If I clear the console content and reload the webpage the error console shows only a couple of messages. YouTube home page give a lot of yellow triangle warnings about 200, but no red warnings, do you get red warnings.
You could also try on the problem sites eg YouTube changing the permissions with tools -> Page Info | Permissions
Did you try the Basic Troubeshooting suggestion of making a new profile. (Heeding the warning not to delete settings, otherwise you loose all bookmarks etc) did that help ?

If you use ZoneAlarm Extreme Security then try to disable Virtualization.
Do a clean reinstall and delete the Firefox program folder.

Whenever you try to save a PDF file to a location other than the default location ('My Documents'), Firefox freezes & you have to go to the 'Task Manager' to exit Firefox and stop the error, so you can load Firefox again.

Whenever you try to save a PDF file to a location other than the default location ('My Documents'), Firefox freezes & you have to go to the 'Task Manager' to exit Firefox and stop the error. I have Windows XP (Media Center Edition) and all updates (Firefox, Adobe PDF, Microsoft, virus protection, etc) are installed. This has only been a problem since Firefox 4, and isn't a problem in Internet Explorer.

Hi David,
Thank you for your detailed question. It sounds like the real issue is pdf files. Are there any antivirus/firewalls that might be blocking this specific file type? or are there any preferences in your control panel that might be blocking this?
Do you have any stored preferences for PDF files in Firefox?

Hi, I have HTC Legend on Android 2.2.

OK Vicky, good clues...
See if this helps...
Open Keychain Access in Utilities, use Keychain First Aid under the Keychain Menu item, then either check the Password under that item, change it, or delete it and start over. See if there are duplicates, should be one for Incoming & one for Outgoing.

If Keychain First Aid finds an issue that it cannot repair, or if you do not know your keychain password, you may need to reset your keychain.
