Firefox says "Unable to connect" but Interent Explorer works fine

Randomly one day, opened up firefox and it was unable to connect. I have gone to the support sites I have followed everything, yet nothing works. Internet Explorer works just fine so its not my connection. I have also uninstalled and re-installed the entire program it still doesn't work.
== This happened ==
Every time Firefox opened

Did the problem appear after updating your version of Firefox? It could be your Firewall does not recognize the new version. See:

Cant connect to ebay via firefox says no dsl connection but there is, works fine on internet explorer

have checked internet connection, fine. Can access other sites but not ebay, help

Some problems occurs when your Internet security program was set
to trust the previous version of Firefox, but no longer recognizes your
updated version as trusted. Now how to fix the problem: To allow
Firefox to connect to the Internet again;
* Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
* Remove Firefox from your program's list of trusted or recognized programs. For detailed instructions, see
'''[https://support.mozilla.org/en-US/kb/configure-firewalls-so-firefox-can-access-internet Configure firewalls so that Firefox can access the Internet.]''' {web link}
Type '''about:preferences#advanced'''<Enter> in the address bar.
Under '''Advanced,''' Select '''Network.'''
Look for '''Configure How Firefox Connects''' and press the '''Settings''' button.
Check the settings.

Firefox won't work, every website has an error like the internet isn't connected but internet explorer works fine, how do I fix it?

This is the message I get for EVERY website I have tried: Firefox can't establish a connection to the server at support.mozilla.com. I have checked the firewall and didn't notice any problems but I might not know what to look for. I have uninstalled and re-installed the program and still have the problem, I have also tried on different wireless internet signals and restarting my computer. I am using windows 7.

No problems here with that visited counter on your website.
Which extensions did you install?
Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Appearance/Themes).
* Don't make any changes on the Safe mode start window.

When open Firefox 8, says 'Unable to connect' and no websites work. Internet connection is fine. Please help :(

My Firefox automatically updated to Firefox 8. Since doing so, when I open the browser the screen displays a box saying 'Unable to connect' and says the same for any website. My internet connection is fine. I uninstalled and installed Firefox again, but problem persists. Please help as this is really frustrating me :(

Did you try this?

Firefox cannot load anything but ms explorer works fine

when i try to access any site i get message 'done' at bottom left of screen but nothing else.
firefox has worked fine before
explorer works fine

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.

Internet Explorer works; Firefox doesn't; every website on Firefox says 'unable to connect.'

I opened Firefox. When I try to get into any website, the error message 'unable to connect" appears. I switched over to Internet Explorer and it work fine - I can connect to the Internet with no problems. So, what's going on? How can I fix it?

Firefox says "Unable to Connect" to two specific websites

I cannot access two site through Firefox, one is facebook.com. The message says, "Problem Loading Page. Unable to connect. Firefox can't establish a connection to the server at www.facebook.com...." Another website is a Proboards site. I can get to proboards.com, but the specific board I want to access. I am able to get to all other web pages except these two. I am also able to access these websites from other computers using the same internet connection. I have disable all add ons and uninstalled all antivirus software. Firefox is checked as an exception to the Windows Firewall (I even tried turnign off the Firewall to see if that would work, but it did not)
== URL of affected sites ==
http://www.facebook.com/

Server Facebook blocked your IP so you can use DSN Google to access internet easyer and faster.With this DSN you access any website including Facebook.
Setting DSN Google:Control Panel->Network Connections->Local Area Network->Click right-mouse chose Properties->Internet Protocol (TCP/IP) and click Properties->Use the following DNS server addresses-> fill Preferred DNS server: 8.8.8.8 and Alternative DNS server: 8.8.4.4 and final Click Ok->Ok.

When I try to activate imessage or facetime a message pops up that says to check my network connection but safari is working fine

I know that my apple ID and password are right because I checked online and I tried changing my DNS but nothing has worked. I am in college and use the university's wifi could that have something to do with it?

1. Log in as a local administrator.
2. Take the ownership of the C: driver.
3. Add your ID in security and give full access.
4. Change the NTFS permission back to normal.
5. Reboot the computer.

IPod Touch 3G Wifi Problem...says it is connected but doesn't work?

After my iPod connects to a network for wifi, it says that it is connected to that network, and the wifi symbol appears in the top left hand corner to show that it is connected. But, whenever I try to go to Safari or another app involving the internet, the iPod says "invalid argument" and the internet doesn't work at all. How do i fix this problem?

Have you tried the basic troubleshooting here?
http://support.apple.com/kb/TS1398
First try:
- powering off and then a minute later power back on your router.
- Reset network settings on your iPod: Settings>General>Reset
- Resetting youriPod

My device needs restoring but when i press restore it says no internet connection but the internet is fine

My I pod touch is saying to connect to i tunes, I have connected it and press restore, it says it cannot restore as not connected to the internet but I am connected as I can get on other websites, help!!

Hello calthelly,
Thank you for providing all the information about the issue you are experiencing with iTunes. I found an article that addresses the specific error, "iTunes could not contact the iPod software update server because you are not connected to the Internet. Make sure your Internet connection is active and try again:"
iTunes for Windows: iTunes cannot contact the iPhone, iPad, or iPod software update server

My FaceTime won't work it won't let me sign in it says can't connect but my wifi works with my brothers what can I do to fix it?

My FaceTime won't work it won't let me sign in but my wifi is working on my brother what can I do to fix it?

Are you trying to FaceTime to your computer, or iPhone with your iPod? Do they share the same address? If so change the address to one of your devices, otherwise it's like trying to call yourself from the same phone. If not the problem, then I'm not understanding your question. Could you restate it with a little more detail. Good luck.

I was having issues with firefox so I upgraded to firefox 4. I am connected to the internet but when I open firefox or even internet explorer it says Unable to connect problem loading page. Nothing will pull up!!! No help link or anything!!?

I don't know if you are still having the issue but if you are have you contacted your ISP? It sounds to me like it's more of a connectivity issue than a browser problem. I've dealt with similar things several times and in both cases it was something with the modem or an ISP setting.
I'm also wondering if it could be a Wi-Fi issue. Can you log in to your router? (It varies by brand but you would go to a site such as http://192.168.10.1. That is for Trendnet. The information for yours should be in the documentation that came with it.)
You should be able to get the router log in page to come up even if you can't connect to any websites. (Provided the network is set up correctly.)
I also would double check your connection settings (if you're connecting over Wi-Fi) or your ethernet connection. (If you're connected directly to the modem and router.)
Hopefully one of these suggestions will be helpful.

I've downloaded firefox for the first time. My internet works yet when I try and open the browser it says 'unable to connect'

I can't seem to get firefox properly running on my computer. I've installed it, I have internet connection, yet when I open a window and try to go on a site, it says 'unable to connect'

Hello Patrick O' D,
In my experience t here are two different problems with the speed of firefox on startup
# your os and setup
# firefox - and exactly what you use with it
Some factors will be down to your OS and for instance what does start up initially, many of those factors will affect other programmes/applications and not only firefox.
Some other factors depend on Firefox and how you set that up, I always like to have the option to using Firebug but realise it cold clash with other software or slow down firefox startup so I only enable it as I need it. see for instance: https://addons.mozilla.org/en-US/firefox/performance/
