Firefox cannot connect to any websites, although other browsers have no trouble doing so..

I had a problem with a Seagate drive and they connectd remotely to my computer. Hundreds of Windows showed up as part of making the conection and FireFox crashed.
I have since:
* Uninstalled Firefox
* Downloaded a new copy (it fwould not work)
* Followed all advice I could find on the Mozilla support site including clearing all history
Still Firefox will not connect to any website. Here is the error message I get:
Unable to connect:
Firefox can't establish a connection to the server at nytimes.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.

Firefox 6 won't settle down as the next release Firefox 7 is already planned to be released later this month.
You shouldn't be using Firefox 5 because it doesn't have the patch to disable the DigiNotar certificates that was the reason for Firefox 6.0.2. 
Using unsupported Firefox versions is at your own risk and makes you vulnerable to attacks.

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 won't connect to any website, but other browsers will.

When I enter something in the URL bar -- google.com, localhost, http://127.0.0.1/ an IP address, there's a split second flash, then the bar becomes empty again and nothing has happened. It looks like Firefox isn't even trying to connect to the internet.
Yesterday, all was well when I was running FF on Windows 7. After the upgrade to Windows 8 Pro, Firefox failed. I upgraded again to Windows 8.1, hoping for the best, but it's the same problem.
I have walked through the firewall issue, several times (the only one running is Windows' built-in firewall). I eventually uninstalled Firefox, including all my custom settings, and reinstalled from scratch, twice. And even this pure, clean version of Firefox will not connect to the internet.
I'm a computer-literate web developer and would be happy to look at log files, or run some tool (Fiddler?) to see what's happening at a low level, if only I knew where to look.

Others with similar problems please look at the article
* [[Firefox can't load websites but other browsers can]]
MM..,
mm... That just about sums up my thought on reading your question. Rather odd this one. I will list some brief ideas and number them to make them easier to refer to or comment on.
Obviously this does not affect all Firefox 27 on Windows 8. It must be something fairly specific to your setup. I have no idea what your problem is and you have tried some of the obvious troubleshooting steps.
Rather a general shotgun approach but the best I can do is suggest this list
# Clean Install Presumably you will have tried deleting the program path files in order to get a clean install. [[Troubleshoot and diagnose Firefox problems#w_5-reinstall-firefox]]_5-reinstall-firefox (See also note about ESR install)
# Firefox SafeMode will also have been tried [[Troubleshoot Firefox issues using Safe Mode]] Remembering to disable or uninstall plugins, safemode does not do that.
# Try a new clean additional test Profile. [[Use the Profile Manager to create and remove Firefox profiles#w_creating-a-profile]]_creating-a-profile
#Windows Safe Mode
# Install and try Firefox ESR http://www.mozilla.org/en-US/firefox/organizations/
#* As a developer you are probably interested in using that anyhow. Either a customised install as an additional browser http://kb.mozillazine.org/Testing_pre-release_versions#Installing_multiple_versions Or use the unofficial Firefox portable. http://portableapps.com/apps/internet/firefox-portable-esr
#* Helps rule out: Firefox code or feature regressions, Corrupted program files
#* Should quickly enable you to see a working Firefox again
# Run scans for malware problems with multiple tools
#* [[Troubleshoot Firefox issues caused by malware]]
# Is it only network problems ? Confirm you are you able to open local html files on the same partition ?
# Firefox's Network Console should throw light on the situation. There is also the Firefox Error Console and Profiler (Profiler is now built in)

Firefox won't load any websites but other browsers connect with no problem. error message: connection has timed out. deleting browsing history did not work.

I also tries removing firefox and reinstalling it - still did not work.
I checked - the firewall wasn't blocking firefox , so it's not that.
As far as I could find my antivirus (AVG) also was not causing the problem.
I'm at a complete loss - any ideas what has gone wrong?

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.
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}

My Firefox won't load any websites, but other web browsers will. I have tried following the proxy help to fix this, with no luck. What can I do next?

Any website I try to visit using Firefox won't load, it just keeps saying that it is unable to connect. I tried other web browsers, and they work no problem. I tried following the proxy steps provided, but did not help.

Did you check your security software (firewall)?
A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, 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.
See [[Server not found]] and [[Firewalls]] and http://kb.mozillazine.org/Firewalls
If you use a Firefox 4 beta release then you should create a new profile exclusively for the 4.0 beta version and create a desktop shortcut with -P "profile" appended to the target to launch that profile.

Firefox can not browse to any website. my other browsers still work.

I'm running Firefox 6.0.2 and everypage that I try to browse to gets the same response. Unable to Connect. I've tried starting Firefox in safe mode and get the same error. I can use other browsers, and I'm using windows explorer to send this help message.

Firefox cannot load a specific website but other programs can

I have a rare problem with firefox (3.6.18 at the moment)
I have to work with a modified mantis bug tracker and the site wont load (the tab says "Loading..." and the bottom status bar says "waiting yourdomain.com...")
I can reproduce this and seems to be related to the cookies: I have a page with a big image still loading, I submit a form from this page and that is were the problem happens.
From here no page from this bug tracker will load.
This only happens to me with firefox and not with other browsers.
If I clear the cookies, the site will load again.
Hope you can help me
Thanks, Fernando.

Firefox will not open any webpages, but other browsers work. How can I fix it?

Firefox will not load any web pages. I recently ran a registry cleaner/virus scan on my computer and now Firefox 5 will not load ''any''webpages. It displays a "Problems Loading Page" error message. Other browsers still work. I tried uninstalling and re-installing firefox, even restoring to a previous restore point, but nothing seems to work. How can I fix this?

Firefox takes a very long time to open and cannot connect to any website

After updating to Firefox 3.6 and attempting to follow the link to update Flash player (the link was broken), Firefox began to work VERY slowly. I closed the browser and, when I tried to open it again, it took in excess of 30 minutes to open, which it finally did. However, while it was initially able to open some websites (google.com), it reached the point of being unable to open anything at all.

You could try to disable this feature for now by toggling this pref on the about:config page:
*devtools.debugger.source-maps-enabled = false

Firefox cannot open/reload any websites after resuming from a system standby. I have to close the current window and start a new session, then it works again

I am using Firefox v 13.0.1 (Mozilla Firefox for Ubuntu canonical 1.0) on Ubuntu 12.04 LTS. Whenever my system resumes from standby I am not able to open/load any webpages in the Firefox session that was already running before the standby. I don't get any error message, but the page doesn't load at all. If I close the session and start a new one everything works fine.

Not necessarily: rv:1.9.2.8 indicates a Firefox 3.6.8 version

Firefox cannot load a certain website, but other people I have talked to can access that same website.

I was at a chat site today, when it suddenly went blank. I tried to go back to that chat site, but I get the problem loading page error, that says Firefox can't establish a connection to the server at that site. I have asked a few people on my messenger if they can get to that site, and they can. Why can't I?

Other things that need your attention:
Your More system details list list shows two old Flash plugins.
# Shockwave Flash 10.0 r32
# Shockwave Flash 9.0 r124
Update the [[Managing the Flash plugin|Flash]] plugin to the latest version.
*http://kb.mozillazine.org/Flash
*http://www.adobe.com/software/flash/about/
You can find the old Flash 9.0 plugin file NPSWF32.DLL in the plugins folder within the Firefox program folder (C:\Program Files\Mozilla Firefox\plugins\) and remove that file. 
Also remove the flashplayer.xpt file in the components folder, if it is there.

Since firefox 31 my firefox has not been loading pages but other browsers do what is doing on?

I copied and pasted raw data from my firefox:

hello sammboi101, normally such issues are caused by a firewall/security software which doesn't recognize & therefore blocks new firefox versions: [[Fix problems connecting to websites after updating Firefox]]

Firefox cannot connect to the internet...i can get on with int. explorer

I always use Firefox as my browser...may be 4.0...recently, I get a message that firefox cannot connect to the internet. I do have an internet connection, since I can connect with internet explorer...any suggestions?

For possible causes see [[Firefox cannot load websites but other programs can]].

Firefox cannot connect to internet, although internet explorer will, this problem just starter today, any ideas of what I should dpo

Everytime I try to use firefox I get a message saying Firefox cannot connect to the internet. It was working fine yesterday. I can connect without any problems using Internet Explorer, so I know it is not my internet connection?

Thanks, for responding.
I did a hard reset of the linksys router. I changed the name of the wireless network. I did this using the PC that is wired to the router. The PC continues to work just fine.
The G4 continues to be able to log-in in the wireless network, but there is no internet connection with the G4. Under Network Status, the G4 says "Airport is connected to the network. Airport has a self-assigned IP address and may not be able to connect to the internet" Is this something I should try to fix?
Thanks!
