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.

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.

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 update.

My iPod Touvh 4th Generation won't turn on. It will not charge even after I used a few chargers and will not connect to a computer. The Home button is broken and I don't know if the Lock/Sleep button is now broken or stuck as well. What should I do?

My iPod Touvh 4th Generation won't turn on. It will not charge even after I used a few chargers and will not connect to a computer. The Home button is broken and I don't know if the Lock/Sleep button is now broken or stuck as well. I believe there may be a problem with the battery or the backlight. I've had my screen replaced once by some stooges. What should I do?

Try:
- iOS: Not responding or does not turn on
When it says place the iPod in recoverymode use one of these programs.
For PC
RecBoot: Easy Way to Put iPhone into Recovery Mode
If necessary:
Download QTMLClient.dll & iTunesMobileDevice.dll for RecBoot
and
RecBoot tip
For MAC or PC
The Firmware Umbrella - TinyUmbrella
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Firefox will not upgrade the company whose firewall I am behind say that UPX files are not allowed where can I download a Non-UPX latest version

Firefox will not upgrade the company whose firewall I am behind say that UPX files are not allowed where can I download a Non-UPX latest version

UPX is used to compress the Firefox program.
It is not possible to un-compress that file without corrupting it.
Can you use the portable Firefox version?

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
'''[https://support.mozilla.org/en-US/kb/configure-firewalls-so-firefox-can-access-internet?esab=a&s=Configure+firewalls+&r=0&as=s Configure firewalls so that Firefox can access the Internet.]''' {web link}

After updating iTunes to latest version, Firefox will not load.

I installed the new version of iTunes that supports ios6 this morning. Right after that Firefox will not start. It flashes some kind of message in the lower right corner that I cannot read. Task Manager says it is running, but not on my screen.

Look in Processes in the Task Manager. If Firefox is running, you see firefox.exe in there. You can remove it from there.

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.

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 5 will not start with Zone Alarm Ver 10.0.240.000

Firefox updated yesterday and now it will no longer start, it looks like the probem may be with Zone Alarm Forcefield. Does anyone have any ideas how to get Firefox 5 to tun under Zone Alarm Extreme Security? Thanks

Hi,
I'm running Win7 x64 with ZoneAlarm Extreme Security 10.0.241.000
I had the same problem with Firefox 4. After turning off ForceField Toolbar, it started working fine.
Then I updated to Firefox 5 and it wouldn't start, instead it was showing an error message from ZA...
I searched mozilla support and followed the instructions here: http://kb.mozillazine.org/Browser_will_not_start_up
on the topic"Firefox does not start after updating with ZoneAlarm ForceField enabled".
The correct instructions for this ZA version should be: "'''Internet '''-> '''Web Security '''-> '''Settings''', and click '''Clear Virtual Data'''"
After that I could open Firefox again! Then I realized it was still version 4...
I installed the update, and everything went smooth. Checked again if Forcefield toolbar was inactive (it was) and opened a few pages, closed Firefox and opened again. After a while it wouldn't open...
AGAIN the "Clear Virtual Data" did the trick...
This time I clicked on '''Settings '''(next to "Clear Virtual Data") -> '''Advanced Settings''', and turned off "'''Enable Virtualization'''".
Until ZA get a fix for this, either we turn it off or clear virtual data every few moves...
Working fine.
Best regards

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.
