When opening Firefox, no internet connection seems to be established

After a virus scan Firefox is no longer working. After opening, it only shows a white screen and it doesn't seem to be connected to the internet. Even after removing and reinstalling the program the problem remains. What can we do?

Hello,
The Refresh feature (called "Reset" in older Firefox versions) can fix many issues by restoring Firefox to its factory default state while saving your bookmarks, history, passwords, cookies, and other essential information. This does more than simply uninstalling and reinstalling does.
'''''Note:''' When you use this feature, you will lose any extensions, toolbar customizations, and some preferences.'' See the [[Refresh Firefox - reset add-ons and settings]] article for more information.
To Refresh Firefox:
# Open the Troubleshooting Information page using one of these methods:
#*Click the menu button [[Image:New Fx Menu]], click help [[Image:Help-29]] and select ''Troubleshooting Information''. A new tab containing your troubleshooting information should open.
#*If you're unable to access the Help menu, type '''about:support''' in your address bar to bring up the Troubleshooting Information page.
#At the top right corner of the page, you should see a button that says "Refresh Firefox" ("Reset Firefox" in older Firefox versions). Click on it.
#Firefox will close. After the refresh process is completed, Firefox will show a window with the information that is imported.
#Click Finish and Firefox will reopen.
Did this fix the problem? Please report back to us!
Thank you.

Avast detects URL:MAL when opening firefox.No issue with IE or Chrome,after troubleshooting realized problem is NoScript addon.Can it have been infected?

avast -network shield
Infection Details
URL: http://188.24.140.190/
Process: C:\Program Files (x86)\Mozilla Firefox\firefox.exe
Infection: URL:Mal

Hi Tyler,
Thanks for quick reply
Initially after some troubleshooting I noticed that I could make infection pop up disappear:
From Configure how firefox connects to the internet -> changed from "use system proxy settings" to "auto-detect proxy settings" or "no proxy"
With this option modified, the pop up from avast didn't appear any longer when opening Firefox.
However I noticed that both Chrome and IE were set to work on the same "use system proxy settings" and they weren't causing problems...so I assumed the problem still has to be with firefox.
After changing back the option in firefox to "use system proxy" I got again the notice, but saw that when opening firefox in safe mode the issue was gone again.
I tracked it to the no script addon, after removing it, the issue disappear regardless of proxy config settings...when I reinstall it, it appears again.
I am now running in depth virus scans to see were the actual infection is.
It seems to me it is expoiting a vulnerability in this addon, I will try the reset also.

Browsers drop internet connection seemingly at random, solved by reboot

Throughout the day on my MacPro, my browsers will lost their connection to the internet which is immediately solved by quitting and restarting them. This happens in Safari, Firefox and Chrome. There's no specific action I can take to replicated the problem, but it seems to happen more after watching a streaming web video.
When this happens my internet connection as a whole is uninterrupted - FTP transfers and streaming radio continue. Note this problem also happens when I have no network activity going on in the background as well.
Is this a common issue? Is there a likely culprit?

Possible solutions:
System Preferences/Internet & Network/Network
Unlock the padlock
Locations: Automatic
Highlight Airport
Click the Assist Me button
In the pop up window click the Diagnostic button.
System Preferences/Network- Unlock padlock. Highlight Airport. Network Name-select your name. Click on the Advanced button. Airport/Preferred Networks-delete all that is not you.
Place a check mark next to "Remember networks this computer has joined." Click the OK button and lock the padlock. Restart your computer.
Check to see if an extra entry is present in the DNS Tab for your wireless connection (System Preferences/Network/Airport/Advanced/DNS).
Delete all extra entries that you find.
Place a check mark next to "Remember networks this computer has joined."

When opening Firefox, I also get a popup page thanking me for installing AOL Toolbar.

Frequently, when opening Firefox 7.0.1 I get a popup page over the home page. The popup page is a Thank You for installing AOL Toolbar. I do not have the toolbar, though I might have in the past. I do not like AOL and want to stop the popup page but have not been able to. I do use Winamp's Toolbar and this could be the source of the problem. If Winamp Toolbar is the problem, I will uninstall it if there is no way to turn off the popup from there. Please assist.

There is some anecdotal evidence that the scripts on the Apple site that are supposed to detect the version of Windows you are running may fail for some users - jumping straight to the "Thank you for downloading ..." page with the installer not having been downloaded. As an alternative, you can go directly to the relevant downloads:
iTunes 12.1.0.71 for Windows (32-bit) - itunessetup.exe
iTunes 12.1.0.71 for Windows (64-bit) - itunes6464setup.exe
There is an alternative downloader for 64-bit editions of Windows here:
iTunes 12.1 for Windows (64-bit — for older video cards)
that seems to address many of the playback issues that some users have been reporting with the full 64-bit version (the alternative installer here is the same architecture as most previous "64-bit" versions of iTunes, i.e., a 32-bit application with a 64-bit installer). The "for older video cards" reference does not seem to fully define the scope of systems for which this alternative works better.
See turingtest2's notes on Troubleshooting issues with iTunes for Windows updates for more details if you're still having problems with installation. This also includes links to the iTunes 12.0 installers if the issues reported with 12.1 suggest it safer to use the previous version.

SQL Developer crashing when opening or testing a connection

SQL Developer closes abruptly when opening or testing a connection.
Here's what I do.
Open SQL Developer.
Create a connection:
Connection Name: [some string]
Username: [username]
Password: [password]
Save password: checked
Oracle tab:
Connection type: TNS
Connect Identifier: somedatabasename
Then I click on "Test" and the application immediately quits. No error messages. The app does the same thing if I save the connection and try to expand its node on the list of connections.
Mind you, if I use sqlplus like so:
[username]/[password]@somedatabasename
It connects just fine.
I captured the output from the command console after SQL Developer crashed:

@Jim:
Thanks for your suggestion. After several hours of experimenting, I've managed to fix my problem by copying the ojdbc6.jar from my ODAC installation and replacing the one in [sqldeveloper root]\jdbc\lib
To whomever has a similar issue: See my original post for what software I was using and their version numbers.

I Hate Bing and when I click on a Firefox NEW Tab and search I keep getting Bing results, I used to get Google which I would like back, my homepage when opening Firefox is not Bing but all tab searches retrieve Bing results.

My homepage when opening Firefox is not Bing, yet for some reason today it started using Bing instead of Google for my NEW tab search results. I already deleted Bing from the search bar, no results. Deleted Bing from my computer's control panel. I just want to be able to click a new tab and have my results in google as I always have.

hello, you have a malicious addon present on your pc. <br>please go to ''firefox > addons > extensions'' & remove ''LyricsParty''.
also go to the windows control panel / programs and remove all toolbars or potentially unwanted software from there and run a full scan of your system with the security software that you have in place and different other tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes] & [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner].

When opening Firefox I get a Java Scripts error message and Firefox will not always open

When opening Firefox browser I get an error message from JavaScript Application: "TypeError:components{cid} is undefined. Sometimes the Firefox browser will not open; sometimes it does. Very annoying!!
Richard

This can be caused by an add-on that says it is compatible with Firefox 4 but isn't quite compatible. This thread has more information: [https://support.mozilla.com/en-US/questions/729606 Javascript pop errors stating: TypeError: Components.classes[cid] is undefined | Firefox Support Forum | Firefox Help].
Does that help?

Unless you have an Internet connection you cannot access iCloud. You can download your music from iCloud to store permanently on your iPhone, but only when you have an Internet connection to do so.

When opening Firefox 6 I receive 2 JavaScript Application errors; the 1st is "TypeError: Component.classes[TvtPwmComponent_CID] is undefined". The 2nd error is; "TypeError:Components.classes[componentid] is undefined." How can I correct these errors?

The 2nd error is; "TypeError:Components.classes['''componentid'''] is undefined." and upon closing Firefox 6 I receive the following JavaScript error; "ReferenceError:'''M_caFxTBobj''' is not defined."

This issue can be caused by an extension that isn't working properly.
Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions 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.

After downloading iTunes, it won't open stating need Internet connection. But already connected to Internet. Happened on 2 different computers. How can I resolve this?

After downloading iTunes,it won't open stating need Internet connection. Have Internet connection but program apparently doesn't recognize it. How can I resolve. This happened on 2 different computers.

If the modem is also a router, either use the modem in bridge and run pppoe client on the TC.. that is assuming ADSL or similar eg vdsl. If it is cable service.. and the modem is a router, then bridge the TC.. go to internet page and select connect by ethernet and below that set connection sharing to bridge.
Please tell us more about the modem if the above gives you issues.

Problem recording to FMS when client has poor internet connection

Hi,
I am trying to implement a simple system that allows users of our website to leave an audio message. The audio recording tutorial shows a simple example of using the NetStream class to "publish" the audio stream to the FMS. During testing, many of the recordings were cut cropped (missing bits from the beggining or end), ended prematurely or had skips. This happens almost always when the user's internet connection isn't particularly good or is a little unreliable.
Is there anyway to resolve this, short of demanding our users guarantee us they have a perfect internet connection (which is unrealisitc). Is there a way for the stream to be cached locally and published to the FMS to increase tolerance to connectivity issues?
Any help or advice would be appreciated
thanks

bump, anyone?

I was downloading some songs when I lost my internet connection. There is no sign that these songs reached my iTunes but i have been charged for these songs anyway. What should I do?

It's possible that the message you got was to update the AirPort Express Base Station's (AX) firmware...and that something might have gone wrong during the upgrade.
Let's start by performing a "factory default" reset on the AX to get it back to it's original "out-of-the-box" condition.
Then, let's set it up to work with your cable modem...
AirPort Express Base Station Setup (AX) w/High-Speed Cable Modem
Modem/Router Power ReCycling (optional)
- Power-off the Cable modem, AX, & computer(s). (Wait at least 30 minutes. If possible, leave the modem off overnight.)
- Power-on the Cable modem; Wait at least 30 minutes.
- Power-on the AX; Wait at least 5 minutes.
- Power-on the computer(s)
Setup the AX
With the network components powered down, set up the AX, using the AirPort Admin Utility, either connect to the AX's wireless network or connect your computer directly (using an Ethernet cable) to the Ethernet port of the AX, and then, try these settings:
AirPort tab
- Base Station Name: <whatever you wish or use the default>
- AirPort Network Name: <whatever you wish or use the default>
- Create a closed network (unchecked)
- Wireless Security: Not enabled
- Channel: Automatic
- Mode: 802.11b/g Compatible
Internet tab
- Connect Using: Ethernet
- Configure: Using DHCP
- WAN Ethernet Port: Automatic
Network tab
- Distribute IP addresses (checked)
- Share a single IP address (using DHCP & NAT) (enabled)
Do not, at this point, set up any security (i.e., WEP/WPA encryption, closed network, etc.) to first make sure the AX is operating properly. Try to access the Internet wirelessly with your MacBook. If you're successful, go ahead and add any security features you wish.
