Firefox will not connect to serever.

Firefox will not connect to server. Other application connect.
I have removed and reloaded firefox several times.

Which security software (firewall, anti-virus) do you have?
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.

Firefox will not connect to internet, period; all troubleshooting on my end has been done

Firefox will not connect to any webpage. This is occurring daily and constantly. I have road runner service for internet access. I have done all troubleshooting on my end -- emptying cache, resetting modem, resetting router, etc. I cannot connect to internet. My computer is checked -- Windows troubleshooting, etc. Firefox has also been crashing at least 4-5 times a day on average. Sometimes I have a couple of days free of crashes. Most times, this is becoming infuriating. I have to be on line for work. I have gone through checks and pinging with the internet service through Time Warner Cable. What is going on? It's impossible that every website in the world has a broken server!!!

So you also rebooted your router correct? Does the iPod still connect okay to other networks?

Firefox will not connect to any site since downloading new upgrade.

Firefox will not connect to any websites since installing the latest upgrade. Google Chrome and Internet do work.

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, then add it back. For detailed instructions, see

1st problem see http://kb.mozillazine.org/Firewalls
2nd problem, to close Firefox properly use File > Exit
:not with the [x] in upper right corner which close window
:see http://kb.mozillazine.org/Firefox_hangs#Hang_at_exit
:if restarting use "Restartless Restart" extension as mentioned there.

Firefox will not connect to certain major `websites" Why? I can go to Google and access

In the last 4 days Firefox will not connect/find certain major websites. Basically says that server not found.
What's the deal here? I use windows 7 and have the most current
firefox update.

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.

After updating to Firefox 3.6.15, Firefox will not connect to the Internet, even after uninstalling and re-installing Firefox in my Windows XP environment.

After downloading the Firefox 3.6.15 update, my problems began. Firefox would not connect to the Internet. When I rebooted my PC, Firefox said that it couldn't access any Web sites. I uninstalled Firefox, then downloaded and installed Firefox 3.6.15. I still have the same problem: Firefox will not connect to the Internet. I am running Windows XP, service pack 3. I never had problems with Firefox until I installed version 3.6.15.

I have XP Pro. I tried installing 3.6.15 and could not open it. I did a system restore and 3.6.14 would no longer open. I tried again installing 3.6.15 and got a message that the previous version had not uninstalled properly. Tried uninstalling.
As a precaution I used MozBackup to save my bookmarks etc. and also saved a system restore point.
I then clicked Start, My Computer, drive C, Program Files and deleted the Firefox folder.
I installed 3.6.15 and it is now working fine with all my bookmarks and addons loaded automatically.

After installation of 8.0.1 Firefox will not connect through Zone Alarm Firewall

After updating Firefox from 8.0.0 to 8.0.1, Firefox would no longer connect to either my LAN or the internet. Internet Explorer, Outlook and Ping work fine, the latest version of Chrome also will not connect. If I turn off the Zone Alarm Free firewall, everything connects again.

Your firewall is not recognizing the new version; it is just doing its job.
#Exit Firefox (''Firefox button'' > Exit or ''File > Exit'')
#Remove references to firefox and plugincontainer from your firewall list of allowed programs
#Start Firefox, let your firewall detect the new version and give permissions to allow Firefox access to the internet
'''NOTE:'''
*In ZoneAlarm 10.1.056.000, the ZA toolbar only works with Firefox 7.
*In ZoneAlarm 10.1.065.000, the ZA toolbar only works with Firefox 8.

Firefox will not connect to any website but other browsers can

I installed firefox on my new advent laptop running windows 7 but it will not connect to any websites. I can connect using chrome or ie no problem but i always preferred firefox as a browser, i have tried changing settings and turning off my firewall but still having no luck

Okay, here is my answer to this problem. At least it fixed my problem and firefox now works fine.
Prior to this problem I was running zonealarm (free firewall) everything worked fine until I removed zonealarm free and installed Comodo free firewall. That is when the trouble started. firefox failed and IE kept working. I tried everything posted here nothing worked for me.
I resorted to "REGEDIT" and removed everything in my registry that regedit would allow that had the name of "zonealarm" on it. Didn't even have to reboot my system, firefox worked first thing. Everything else is fine also.
[note: this is not a slam against Lavasoft's ZoneAlarm firewall. It is just that UNINSTALL programs do not always do a thorough job of removing parts of programs in your systems and registry cleaner programs do not pick them up either.]
USE CARE, "REGEDIT" IS A POWERFUL AND DANGEROUS TOOL TO USE ESPECIALLY IF YOU ARE NOT A SOMEWHAT ADVANCED USER. USE CARE WITH "REGEDIT!"
Good luck.

FIREFOX WILL NOT CONNECT TO YOUR SERVER FOR UPDATES. HOW DO I FIX

TRYED TO FOLLOW YOUR WEB SITE TO MANUAL UPDATE FIREFOX BUT IT WILL NOT CONNECT TO YOUR SERVER. HOW TO FIX. ALSO BROWSER HAS BEEN HIJACKED HOW DO I FIX THIS. I TRY TO SEARCH FOR FIREFOX AND I END UP AT MANY DIFERANT SITES THAT I DID NOT ASK ABOUT.

I'm having the exact same issue. I'm connected to the VPN, but I can't mount or otherwise connect to the shared drive. Did you ever resolve this?

Firefox will not connect to another web site and it will not reopen after I close it.

I have removed Firefox and reinstalled it. I have tried to disable addons but it still will not open unless I reboot my computer. If this problem cannot be fixed easly, I will have to remove Firefox for good. When it is open, it will not connect to any URL I enter. When I close it it will not reopen and I get a message that says I have to restart Windows. This bug needs to be fixed. It worked one day and the next day it would not work.

Beginning last week, Firefox will not connect to the internet.

Firefox will not access the internet at all. This began suddenly and not immediately following a change in Firefox or my computer.

Maybe you have a malware infection.
See:

Do a malware check with some malware scanning programs. 
You need to scan with all programs because each program detects different malware. 
Make sure that you update each program to get the latest version of their databases before doing a scan.

Firefox will not connect to anything past my Yahoo homepage

I am using Firefox 4.0 beta. Last night I began having problems with the browser not connecting with anything, including the Mozilla server. I finally gave up and went to bed. This morning the same problem continued, so I used Internet Explorer 8 to connect to the internet (worked fine), and came to this site to report my problem. I have checked my router (brand new) and internet connections and they are all ok. I am using Windows 7 on a Dell Studio 17 laptop. I have recently downloaded Network Magic from Linksys, but have not installed it yet.

Firefox will not connect to the internet.

When I try to connect with firefox it gives me the message that firefox was unable to connect to the server that I was attemting to connect to, and then it asks me if I would like to try agian. I still have internet explorer on my computer and it connects just fine. I need to have firefox working, or I will have to go with google chrome or something different, as internet explorer is not recomended to use on most online college applications and it is finals week.

Windows 7 has a firewall which controls access to the internet on a program by program basis. It is possible that Firefox is not in the firewall's list of a approved programs.
Go to the Help feature and search on Firewall and read the information on how to allow a program internet access.
I don't use the Windows 7 firewall, I use ZoneAlarm's firewall. When I installed ZoneAlarm, I disabled the Windows 7 firewall and have never used. Thus, I can't give you detailed directions as to what you might need to do to allow Firefox to use the internet.
NOW - are you able to get to the internet with Internet Explorer, just as a test?
If not, then the problem may be elsewhere, such as your internet connection - dialup, DSL, Cable, etc.
