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

Firefox will not connect to any website following upgrade. Anti-malware is not blocking AFAIK

Firefox will not connect to any website *at all* since upgrading to latest version. No mention of Firefox anywhere in firewall- and anti-malware-related services (Intego VirusBarrier X6 V10.6.13).

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.

After a crash and update firefox will not connect to any webpages. Internet explorer is working fine. What's going on?

Firefox crashed. Closed all my windows - did the auto update thingy with accompanying message. Brought up the windows that had closed as usual - all said "problem loading page". Firefox will now not connect to internet. It's not a problem with my connection etc - internet explorer is working fine. Anyone else have this problem today?

So, it's been 13 hours now and no answers. From reading the Airport Discussion board "
Airport has a self assigned IP address, 169.254.175.198 and will not be able to connect to the internet"
is a very common problem and I find it hard to believe Apple has not responded with a fix. I may have to take it into a Genius Bar and see what they can do but I do not have high hopes.
You know, I was talking to someone last week and the name Apple came up. "Ah", he said, "the Evil Empire". Their success has made them much more brash than MS ever was.

When I open Firefox, The tab keeps quickly flicking between "Connecting" and "New Tab". The browser will not connect to any site.

This occurred straight after visiting the isohunt site. I had a message saying "Firefox is preventing
IsoHunt from installing a program, will you allow?" (or words to that effect). I gave permission then the problem started.
I have used Firefox on my iMac for a long time without any problem. I'm running OS X 10.7.5
Hope you can help

Start Firefox in [[Safe Mode|Safe Mode]] to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
*Do not click the Reset button on the Safe mode start window or otherwise make changes.
*https://support.mozilla.org/kb/Safe+Mode
You can use one of these to start Firefox in Safe mode:
*On Windows, hold down the Shift key while starting Firefox with a double-click on the Firefox desktop shortcut
*On Mac, hold down the Options key while starting Firefox
*Help > Restart with Add-ons Disabled
If it does work in Firefox Safe-mode then disable all extensions (Tools > Add-ons > Extensions) and then try to find which is causing it by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

It used to work just fine and suddenly crashed. I tried creating a new profile, but it would not load the profile manager either. I have also tried uninstalling and reinstalling it to no avail.

Firefox will not connect to any website

I use Firefox to connect to the internet, on a WindowsXP and Windows 7 machine. A day or two ago, both had updates added on shut down. Now, Firefox doesn't work on the Windows 7 machine. Error message looks like: "Unable to connect
Firefox can't establish a connection to the server at www.google.com.
The site could be temporarily unavailable or too busy. Try again in a few
moments.
If you are unable to load any pages, check your computer's network
connection.
If your computer or network is protected by a firewall or proxy, make sure
that Firefox is permitted to access the Web."
Internet Explorer works. Added Mozilla to list of allowed sites on the Firewall, still same message. Removed and reloaded Mozilla, still same message. I assume the Microsoft update prevents Mozilla (the old "DOS ain't done till LOTUS won't run" updated to "Windows ain't done till Firefox won't run") from working.

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?

I've been working on our church website and suddenly, my computer will not connect to the site. I keep getting a message saying that the the connection to the server was reset while the page was loading. Does anyone have any ideas of how I can fix this?

I've been working on our church website and all of a sudden this week, my computer will not connect to the site. I keep getting a message saying that the the connection to the server was reset while the page was loading. Does anyone have any ideas of how I can fix this?

The "The connection was reset" error message can be caused by a bug fix for the BEAST (Browser Exploit Against SSL/TLS) attack that the server doesn't handle.

Since updating to Firefox 4 on my OSX 10.5.8 mac Firefox will not go to any website

Since updating to Firefox 4 on my OSX 10.5.8 mac Firefox will not go to any website. Firefox will launch but it won't load anything, the page is entirely blank - no home page loads - nothing. Also - It will not let me install any add ons. I've tried uninstalling and reinstalling to no avail. other apps such as Safari and Mail work as normal. I need Firefox - please help if you can. Thanks

You don't. Since you have an Intel Mac, buy a Mac OS X 10.6 DVD from the online Apple Store.

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.
 Please mark "Solved" one answer that will best help others with a similar problem -- hope this was it.

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.

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.

What is polipo and how do i get it? My tor access will not pull up any sites without it.

What is polipo and how do i get it? My tor access will not pull up any sites without it.
== This happened ==
Just once or twice
== tried to load any site: yahoo, gmail, etc.

Thanks for the response Steve. I can create a .flv file, I can create an .avi file and I can burn to a file. However, using Premiere, when I drop that .avi into the new timeline and try to burn it to disk, I get the same message" operating system error: number 0x000004c8- The requested operation cannot be performed on a file with a usermap". It would be good to be able to burn from Premiere Elements but I cannot seem to. However, as you suggested, I have a work around.
I've done some research and it seems usermap is connected to Windows 7 permissions and I have had a problem in PE9 accessing files and getting a permissions error. Don't know if this is a PE9 conflict or just a W7 issue. If you have any thoughts, I'd appreciate them. If I find anything further I'll post it here.
Cheers

IPAD2 not connecting to some sites since IOS update

Since the recent IOS 8 update, my IPAD will not connect to some sites. It reads servere not found. I'm trying to get onto my work site which is very important. Now, my IPAD seems useless for work. I have turned off and back on which did not help. I have read that resetting it doesn't help either. Please help.

i checked for updated firmware on the d'link dir-615 router back in september when this first happened (after the ios6 update) but the firmware was already up to date - although the last update was 2009.
This was my first clue.
After further research, I discovered that all DIR series products have been discontinued by D'Link. This means that when apple is preparing for a software update, it requests all software/hardware specs from wifi router companies like D'Link, Netgear, Garmin, Cysco, etc. Since D'LInk no longer produces DIR series routers, they did not provide the info. D'Link only provided info for it's newest line of wireless routers.
Leaving all existing DIR users in the dust, with a failed strategy that we'd all buy the new line of wifi routers.
Yesterday, I purchased an Apple wifi router, although pricey at $99, i plugged it in, typed the network name and pw want to use, and it was up and running in less than 5 minutes. The apple router will recieve software/firmware updates just as my iphone, macbook, & ipad does. Everything is working perfectly, and the higher price is worth the convenience and reliability.
If anyone makes it this far, the only thing left would be to check with your internet service provider (comcast, RCN, etc) and make sure you have the most up to date modem. some folks are unable to send text & pic messages on wifi using an out of date modem. (i didn't have to replace mine, but i'm also not having this issue now that i have the new apple wifi router.)
Hope this helps at least a few people out there.
