Firefox won't connect to internet but IE will!!

I'm using latest edition of Firefox on windows 07 laptop. Two days ago my internet connection slowed significantly (i was only one) for few hours but then things got to normal. My computer updated (windows) last night and when tried to turn on firefox it won't connect or load website pages. First it said errror in my connection, now message says 'the connection has timed out'. I have done everything stated on firefox support (checked proxy - am on college network so it was on auto and I switched it to no proxy - no luck), I checked my firewall (managed by mcafee) and even though windows is not being used on my laptop I added firefox just in case - no luck. I did the other steps on the page - no luck. IE is working fine and at reasonable speed so it's not the connection.
Any help would be greatly appreciated!!
Edit: don't know if this may help but googlechrome won't work for me either - it opens, and tries to connect to page but never does. . .

[[https://support.mozilla.com/en-US/kb/Cannot%20connect%20after%20upgrading%20Firefox?s=cannot+connect+after+upgrading+firefox&as=s]]
For me the problem was McAfee Security Center running on Windows 7. I reset McAfee and Firefox connected again.

Admin user account won't connect to internet - but guest will.

I'm having a very strange problem with my imac. When I am signed in using my normal admin account, the internet won't work. Or if it does it is brutally slow. And as long as I have the my computer plugged into the internet... whether it be ethernet or wifi, no one else in my house can connect to the internet either, or it's brutally slow as well. The second I unplug the ethernet cable from the back of my computer, everyone else's computer on my home network works perfectly.
The only way I can avoid this problem is to sign on to my imac with the guest account, in which case the internet works fine on my computer and everyone else's. Does anyone know how to fix this? I really don't want to just start using the guest account... I am a photographer and all my info, apps, etc. I use for my business are in my normal admin account. Any help will be much appreciated. Thanks, Beverly
I am running Lion 10.8.5

This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve your problem.
If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
Below are instructions to run a UNIX shell script, a type of program. All it does is to gather information about the state of your computer. That information goes nowhere unless you choose to share it on this page. However, you should be cautious about running a program at the instance of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them.
Here's a summary of what you need to do: Copy a line of text from this web page into the window of another application. Wait about a minute. Then paste some other text, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in your browser, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign ($) or a percent sign (%). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important.
If you're not logged in as an administrator, you won't be prompted for your password. The test will still run. It just won't do anything that requires administrator rights.
The test may take up to a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. There is no indication of progress until it's done. Wait for the line "[Process completed]" to appear in the Terminal window. If you don't see that line within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report your results. No harm will be done.
When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
When you post the results, you might see the message, "You have included content in your post that is not permitted."

I have windows 8.1 and firefox won't play youtube videos but IE will. I have tried reinstalling firefox, flash, java. Resetting firefox don't help, disabled hardware acceleration, protected mode 0 in the mms.cfg file. Nothing will play on youtube in firefox. It says "an error has occured, please try again later". The ads play fine though. Everything plays fine in IE. I have tried different versions of flash also with no luck. I even restored the system to a previous iso image with no luck. Does anyone have a solution?

My Ipod won't connect to Facebook, but it will log onto Skype

For some reason, my Ipod touch won't get on Facebook, but it will operate Skype just fine. Also, it will send me messages when I am offline as well, from Facebook Messenger, and the games that I play. I have tried resetting the internet connection, but it's still the same thing. And I have checked it for updates as well. Can anyone help me?

What is "it" in "Also, it will send me messages when I am offline as well, from Facebook Messenger, and the games that I play."
The iPod can send or receive message without an internet connection.
What iOS version on the iPod?
Have yo went to FB's support site?'Have you tried when connected to another network? Maybe the network is blocking FB

Safari won't connect to internet but other browsers will

Firefox and Chrome can connect to the internet but since upgrading to Yosemite, Safari, iTunes and other Apple Apps have an exceedingly difficult time connecting to the internet. (ie server not found) I have to resort to turning off/on my wifi and/or restarting my computer. All other non-Apple applications can access the internet just fine.

I, too, am experiencing this problem. It occurs with both Safari and Firefox. It wasn't bad at the start; occasionally what seemed like my internet would cut out while I was surfing, but then the problem began to last for longer durations. As of this morning, I've been trying to get Safari to open for two hours with no success.
Here's the specifics. I open Safari. Most times, the load bar will extend about 1/6 the length and stop, displaying my homepage address in the address bar. Sometimes, the load bar will creep halfway, and part of my homepage will appear; typically, images don't load, and sometimes the page format gets wonky. Rarely, the homepage will fully load! I can even move through the homepage's image slideshow seamlessly. However, if I try to go to another page, I'm back at the 1/6 occurrence. Very rarely, everything works fine. Closing the laptop or Quitting Safari kills the connection, and I have to start this stupid process all over again. Finally, Firefox is either all or nothing; either the pages load and work fine, or nothing works at all.
I've done a DNS manual adjustment, I've created a specific Network, I've unchecked Safari from the iCloud options, I've run scans for malware and viruses (and came out clean), and I've done a clean reinstall of Yosemite. There's no need for me to tweak my router or contact my ISP; every other wireless application in our house is functioning perfectly. It's not the wifi.
Nothing's working, and I'm about to throw my computer out a window (not really, just frustrated). Any help would be so very appreciated.

Help! Safari / Firefox won't connect to internet on WiFi?!

I can't connect to internet using WiFi from Safari OR Firefox from my home WiFi (Apple WiFi router.)
Here are weird facts:
- They both work from this laptop at home using Ethernet
- They both worked at AppleStore WiFI today
- Internet at home is fine from other MacBook, iPad and 2 iPhones
AppleStore guy reset a lot of Safari and network settings, suggesting that would fix anything, but it still does not work from this laptop at home over WiFi?!
Any ideas?!
Thanks!
Mark

Thanks, Linc. FYI, I don't believe I've installed any new 3rd pary items for some time (although some of them may have updated to newer versions more recently?)
I've posted output from Terminal commands below. Let me know what you see in it!
FYI, I've been considering updating to Lion OS. Would that a) help me with this situation, and/or b) cause me other new problems?!
Thanks,
Mark

Ipod won't connect to internet but says its on wifi

Okay so I gave up my iPod for lent and of course as soon as I get it, it has problems. My iPod says it's connected to the network but any and every time I use Facebook or google or really anything with internet and it won't connect. It says its not connected to the internet. I've tried factoryr restoring and it wont work . Yeah I just checked and it said the internet connection appears to be offline. Help?!

- Try powering off and then back on the router
- Try resetting your iPod:
Press and hold the On/Off Sleep/Wake button and the Home
button at the same time for at least ten seconds, until the Apple logo appears.
-Try resetting network settings: Settings>General>Reset>Reset Network Settings.

Suddenly iMac won't connect to internet yet laptops will

With no changes that I'm aware of my iMac will no longer connect to the internet. When I open Firefox (or Safari) a window pops up telling me Firefox can't connect to my default URL nor any other site I select. I've tried turning airport off and then back on, resetting the wireless router from Verizon (FIOS) and unselecting and reselecting the signal from the router. Strangely this is not happening on my laptop nor my wifes.
iMac is running Tiger, laptops Panther.

Try with this AirPort Utility 5.3.2 for Tiger update.

Safari, iTunes, iMail, etc... won't connect to internet but FireFox will?

All of my apple applications that use Safari to connect to the internet won't. If I want to connect to the internet I have to use Firefox. I am using a Cisco Linksys Dual Band Wireless N Gigabyte Router with it. My apple my ipod touch which uses safari also will not connect to the internet. This is extremely annoying since I can no longer download anything from iTunes on my iMac or ipod Touch.

I have this problem also. I hope someone out there is reading that can help troubleshoot. When Mail and Safari quit I can still use Firefox. unplugging the network cable and plugging it back in fixes it temporarily. It happens at least twice a day.

Safari won't connect to internet but firefox will

I just set up a home wifi network. Firefox v 22 works perfectly. However itunes store in itunes fails to open. I also just get a blank screen in Safari with no connectivity to the internet. No address I type into the browser bar generates ANY response. Chrome aso works just fine as a browser, so internet connectivity is NOT an issue. Any ideas on a fix to allow these two Apple products to work?

Back up all data.
From the menu bar, select
 ▹ System Preferences ▹ Network
If the preference pane is locked, click the lock icon in the lower left corner and enter your password to unlock it. Then click the Advanced button and select the Proxies tab. If any proxy options are selected, make a note of them and then deselect them. You don’t need to change the bypass or FTP settings. Click OK and then Apply. Test. The result may be that you can't connect to any web server. Restore the previous settings if that happens.

IMac won't connect to internet, but can on internal network

Hi,
I've tried resetting the router and various other things that I found on the internet. I know its not a router problem as I am using my MBP to post this discussion. It won't even connect to the router's internap page. Any thoughts?

With the iMac failing to open any web page outside of your network, then I would be checking the DNS setting in System Preferences > Network > Wifi > Advanced. Compare what you have here to what the MBP has set.
But with the iMac also failing to connect to the routers internal web page then you've got additional problems beyond DNS. Using the MBP as a reference, if you make a note of the TCP/IP network settings in the Advanced section as shown above, is the iMac using the same? (apart from the IP address which should have the last number set to a different value).

IPod Touch 4G Won't Connect to Internet but No Problem with Nintendo DSi...

My sons new iPod Touch 4G 32GB won't recognize any networks. We have manually entered the name of our network and entered the password but to no avail.
I was able to get my daughter's new Nintendo DSi online within minutes but the iPod just won't work.
We have updated the firmware on our router, rebooted our router, reset the iPod, read the iPod manual, we've tried EVERYTHING.
Any suggestions?
Thanks for your assistance!!

Downloading FireFox, won't connect to internet upon download

All of a sudden FireFox stopped working. I uninstalled it to see if maybe there was a conflict somewhere, reinstalled it and am still getting the same message that it can't connect to the internet. Opera, Chrome, IE, Safari all work fine. Can't find a solution to this problem.

For me the problem was McAfee Security Center running on Windows 7. I reset McAfee and Firefox connected again.

Firefox won't connect to internet but IE will!!
